Hi guys, I will finish school in like a month and I am planning on building a new computer afterwards, based on a Ryzen 7 1700X. Currently I am using Windows 10 as my OS but I am not really liking it, so my plan is to switch to a Linux distibution such as Linux Mint. The only problem with that are the games (and some other programs). Maybe you watched the WAN-Show where Luke said the he was planning to build a machine to run Linux and Windows and kinda stream the game running on Windows to the other platform.
(I hope you understand me.) That's also what I roughly had in mind: My idea was using KVM (Kernel-based Virtual Machine) to run Windows, because I don't know if running it on a usual VM would bottleneck it. So I wanted to ask you guys if you have any experience with that or some other ideas. You have the right idea to start with but it's just the beginning, there will be many obstacles to overcome. With trial and error you will figure it out. So yeah, let Linux use some onboard graphics card and leave the dedicated video card unused so that KVM can use it. But for gaming, I would forget the number of cores and focus on single core performance. With games in mind, Intel and NVIDIA perform better on Linux (with proprietary drivers) and you won't even need to virtualize Windows.
For those that fail (and there really aren't many today if you know what you're doing) forbid that Linux touches the dedicated card, meaning avoid to load drivers. This can be done with some easy blacklisting in the Grub boot entries. And finally, after configuring passthrough and all that jazz, let the Windows drivers take hold of that video card. If the host claims it, then the KVM guest won't be able to access it directly. And I understand why you would want to avoid dual-boot.
It's just much more comfortable to double click on your desktop and launch Windows as a slave, like it's supposed to be play, then close it, while the Linux God watches over everything. Not to mention whatever you have open in the background will still be there and you can continue where you left off. There were some interesting and in-depth experiments on reddit. Look for KVM and passthrough stuff around there. And since you didn't buy anything yet, and want to run Linux don't just be set on some hardware and then figure out how to make it work.
You have the chance to inform yourself better and choose hardware that gets along well with your new OS. Don't miss that chance, you'll be sorry later. Get your eyes on every benchmark you can find (of course, done on the Linux platform). Edit: I have added some info in the beginning of this post.
Thanks a lot for this answer @slicknux You exactly understood what my mindset is The reason I thought going with AMD for the CPU would be a good idea were the more cores you get, while not paying ridiculous amounts of money. And the 1700X apparently doesn't perform to bad in games. For the GPU I planned on using a NVIDIA card anyways. I am also looking for some reports about virtualization on Ryzen right now, reading about people that managed to do it with HyperX for example: Didn't find anything about UnRAID yet. Also I will definetly keep informing myself and post my results.
This topic is always interesting to me. Currently I dual boot windows/Ubuntu 16.04 at home and I like to live in Linux for the most part, but I find myself switching to Windows to play certain games. The idea of a Passthrough is pretty darn close to what I'd be looking for but still doesn't completely scratch the Linux Gaming itch. What i'd REALLY like is for Vulkan (or OpenGL) to really take off and start to make gaming on Linux a true competitor. Windows cornering the market with DirectX is just depressing. If I didn't game on my PC I wouldn't be running Windows at all anymore.
Good luck with this KVM project. I'm really interested to see how it turns out!

OpenGL has really progressed over the past few years, especially with SteamOS and Valve streamlining it. We've been seeing more and more games come compatible on Linux, albeit some ports don't utilize OpenGL well. I personally do not run Windows at all. I abandoned ship after Windows 8.1 crapped out on me 2 years ago, and have been running Ubuntu ever since, and I've gotta say, I'm glad I made the switch.
The only downside is that about 30% of my steam library is unavailable, but most of these games are really old and outdated. The new(-ish) games such as Saints Row and CS:GO run pretty well. I am really impressed with Valve, and how optimized their games are on Linux.
I see no difference between CS:GO operating on Windows and it operating on Linux on the same settings.

I'm unaware of how well Ryzen handles passthrough, but this explains the basics of setting up GPU passthrough for gaming. WARNING: GPU passthrough and VAC: Competitive gamers playing on servers protected by may want to think twice before setting something like this up as their primary gaming machine, as VAC will refuse to run if it detects it’s in a VM (much like some malware). However most of the VAC games should run on Linux. I thought about GPU passthrough again that night and I figured, that with UnRAID, I would need 3 discrete GPUs, since Ryzen doesn't have a IGPU? Anyways, the approach of using something like VmWare + passthrough seems to be the better way to go.
I will now look up, which of my programs are incomatible with Linux and shre the information in a future post. I personally do not run Windows at all.

Right now I am not sure if I want to try gaming on Linux or if I want all my games on WIndows. The problem is, if I plan on gaming on Linux, it gets the better GPU (I can't afford 2 top-of-the-lines) so if a new game comes out that doesn't run on Linux, I can't play it with the worse GPU. Right now I am not sure if I want to try gaming on Linux or if I want all my games on WIndows.
The problem is, if I plan on gaming on Linux, it gets the better GPU (I can't afford 2 top-of-the-lines) so if a new game comes out that doesn't run on Linux, I can't play it with the worse GPU. Using the better GPU in a virtual machine via passthrough doesn't make it permantanly attached to it, so if it comes to that you could still switch it back and forth. But to be frank it's probably a better idea to just try and see if what you're looking for works well or has a decent alternative under Linux. Nowdays many games on Steam have Linux ports or can just run well via Wine. Those are the parts I am planning to use right now (may change due to research etc): CPU: CPU Cooler: Motherboard: Memory: (not sure about that one, may change; also I want that much memory for emulating Android devices and such) Storage: (for Linux) (for Windows, already own that one) Video Card: (already own that one) Case: (may change, just like it because it's something special) Power Supply: note: Pricing in Germany (/europe) is ridiculous: In the USA you can get those parts for about 2200$, in Germany you have to pay 2400€ (which would be around 2575 USD).
After thinking about CPU options, I still want to stick with the Ryzen 7 1700X. The reasons for that are:. I prefer the additional cores of the Ryzen 7 lineup over the i7-7700K, because I plan to run multiple VMs without one of them suffering from to little CPU time. I don't mind the little fps decrease with Ryzen due to its lower clock speed (regularly up to about 4.1 GHz) compared to the i7-7700K (regularly up to 4.5 GHz), since it does not to be to bad.
Speding 80$ extra for the 1800X over the 1700X seems not worth to me, because you can manually overclock the 1700X to about the same speed. Sure, you will lose AMDs Precision Boost abilities but whatever, my cooling should be good enough. PCs:-. AM4 1700 build. AMD Ryzen 1700 w/ Wraith Spire cooler @3.75 1.269V - ASrock AB350M Pro 4 - 16GB Corsair Vengeance 3000Mhz RAM @3066Mhz - Crucial M500 M.2 SSD 240GB - Zotac GTX 1050 mini - 2TB HDD - Thermaltake Core V21 - EVGA Supernova P2 850W Platinum PSU - Pioneer BD writer in external USB 3.0 5.25 chassis. Just had a quick look, and at first glance all I can see is the PSU is waay overkill, just changed that to an 850W tier 1 PSU Will have another look and see if I think anything could be better, but for the most part looks OK. But if you're goign to overclock anyway, just get the 1700, not the 1700x as there's no point, save yourself the $20 or whatever for something else.
I thought the same about the PSU, but somehow a calculater got me to that high wattage. I guess it calculated the overclock wrong. Can you really overclock a 1700 to the same clock as the 1700X?
I thought it would be limited due to a lower TDP.
About Google Compute Engine What is Google Compute Engine? What can it do? Google Compute Engine is an Infrastructure-as-a-Service product offering flexible, self-managed virtual machines hosted on Google's infrastructure. Google Compute Engine includes Linux and Windows based virtual machines running on KVM, local and durable storage options, and a simple REST based API for configuration and control. The service integrates with Cloud platform technologies such as, and to extend beyond the basic computational capability to create more complex and sophisticated applications. What is a virtual CPU in Google Compute Engine?
For the n1 series of, a virtual CPU is implemented as a single hardware hyper-thread on a 2.6 GHz Intel Xeon E5 (Sandy Bridge), 2.5 GHz Intel Xeon E5 v2 (Ivy Bridge), 2.3 GHz Intel Xeon E5 v3 (Haswell), 2.2 GHz Intel Xeon E5 v4 (Broadwell), or 2.0 GHz Intel (Skylake) platform.

These accounts can be used to authorize Google Compute Engine to act on the behalf of the user to access non-sensitive information. A service account is never used to access user-information. Service accounts simplify the process of authenticating from Google Compute Engine to other services by handling the authorization process for the user.
Google offers many types of service accounts, but commonly, users will want to use. How do I create a service account? Compute Engine creates a service account automatically when you create a new instance and for that instance. Projects What are projects?
A is a container for all Google Compute Engine resources. Each project is a totally compartmentalized world; projects do not share resources, can have different owners and users, are billed separately, and are no more accessible to each other than your home computer is accessible to your neighbor's computer. How can I create a project?. to your Google account. If you don't already have one,. When prompted, select an existing project or create a new project. Important: The name you use must be between 4 and 30 characters.
When you type the name, the form will suggest a project ID, which you can edit. The project ID you use must be between 6 and 30 characters, with a lowercase letter as the first character. You can use a dash, lowercase letter, or digit for the remaining characters, but the last character cannot be a dash. Also, you should be aware that some resource identifiers (such as project IDs) might be retained beyond the life of your project.
For this reason, avoid storing sensitive information in resource identifiers.see naming guidelines. Follow the prompts to set up billing. If you are new to Google Cloud Platform, you have credit to pay for your instances. What is the difference between a project number and a project ID?
Every project can be identified in two ways: the project number or the project ID. The project number is automatically created when you create the project, whereas the project ID is created by you, or whoever created the project. The project ID is optional for many services, but is required by Google Compute Engine.

What are Preemptible VM instances, and how are Preemptible instances different than normal instances? Preemptible instances are instances that you can create and run at a much lower price than normal instances, but might terminate if Compute Engine requires access to those resources for other tasks. For more information, see How can I send outbound emails from a Google Compute Engine instance?
Generally, Google Compute Engine blocks outbound traffic through these. However, you can set up a mail gateway through Google using SMTP. For more information, read. There was a host error with my virtual machine and it was restarted.
What happened? A host error means that there was a hardware or software issue on the physical machine hosting your virtual machine that caused your virtual machine to crash. When Compute Engine detects such an event, we add a compute.instances.hostError entry to your operations log. If your virtual machine is set to automatically restart, which is the default, Google will also restart your virtual machine on a different physical machine. In general, physical hardware failures and software failures can happen from time-to-time, but are rare occurrences. To protect your applications and services from potentially disruptive system events like these, make sure you and.

Persistent disks How do I choose the right size for my persistent disk? Persistent disk performance scales with the size of the persistent disk. Use the to help decide what size disk works for you. If you're not sure, read the documentation to. What steps does Google take to protect my data? Can I attach my persistent disk to more than one instance?
You can attach a persistent disk to multiple instances only if the disk is in read-only mode. Disks in read-write mode can be attached only to a single instance.
You cannot attach a persistent disk in both read-write mode and read-only mode at the same time. When should I use persistent disks versus Google Cloud Storage? Both persistent disks and Google Cloud Storage can both be used to store files but are very different offerings. Google Cloud Storage is a massive file container, designed to store extremely large amounts of relatively static data which can be accessed globally, including from Compute Engine virtual machine instances. The following chart provides some information about the characteristic specialties of each offering and what they are best used for.
Hello World, USB devices are more and more present and in use within organizations. Nowadays, plugging in a usb device on a physical computer running Windows or Linux is a breeze. This operation has becomed quite common. Time to time, when working with virtual machines, you might need to present a USB device inside the virtual machine. With virtualization software such as Vmware or MS Virtual pc, you could connect an USB device to the host machine and make it available as a USB device inside the virtual machine. All major virtualization software providers are offering this USB pass-through capability.
I was wondering if Proxmox VE would be offering such capabilities. After some research, I found out that the Linux virtualization solution “KVM” was providing the usb pass-through capabilities. Proxmox ve is based on KVM technology thus there is a chance that this function is integrated within the Proxmox VE solution. After some tests, I was kind of frustrated by the results. Yes, KVM/Proxmox VE support usb pass-through but with some important limitations (for me at least).
Configuring USB Pass-through in Proxmox VE (out-of-the-box solution) I have made some tests in my test environment. The server was runnning Proxmox VE 1.8. There no options available within the web gui to configure usb pass-through so far. You will need to perform some configuration actions from the command line.
I’ve mainly tests usb pass-through against Windows KVM guests virtual machines. I’ve not test the feature against Linux but I’m assuming that the procedure should be similar. So, you wanna use USB devices within your virtual machine. Just perform the following steps: Step 1: Plug your USB device on the Proxmox VE host Step 2: We need to find out the Vendor/Device ID of the usb device you are about to present to a virtual machine. To find this information, you will simply type the following command from the console (or you can use a ssh session) lsusb The screenshot below shows the results returned by the command. In my situation, I have plugged a Kingston USB Device with the following numbering.
13fe:3600 Click to Enlarge picture Step 3: configure the virtual machine to use the USB Device In this step, you have to tell your virtual machine that a usb port is available. To change this, you would simply issue the following command qm set -hostusb 13fe:3600. This command will add a line at the end of the configuration file for the Virtual machine.
You can run this when the machine is turned on or turned off. However, in order to have the changes applied, you will need to stop and then restart the virtual machines. Note: You can edit the configuration file of the virtual machines and manually add the information related to the usb port.
The config file of the virtual machines are all located in the following directory /etc/qemu-server. You can open it and edit it as needed. For example, if you want to enable usb support, you would edit the confiugration file and add the following information: hostusb:xxxx:xxxx. Click to Enlarge picture Step 4: Boot your virtual machine and check that the USB device is present The following screenshot show you the the USB device is indeed presented to the virtual machine. Click to Enlarge picture Step 5: Enabling automount feature (optional) With the current configuration, the virtual machine will only recognize the usb device that you have defined in your configuration file. Groovy for domain specific languages pdf free download.
Moreover, the settings will be persistent. Based on some KVM documentation, it’s possible to configure a simili automount feature. Janome mbx software. In order words, the virtual machine can detect when the usb device is plugged in and removed. To configure this option, you simply need to specify the Vendor ID and no device ID. In other words, instead of typing qm set -hostusb xxxx:yyyy, you would type something like qm set -hostusb 13fe:. Using this notation, you will be able to have your virtual machine detecting when the usb device is plugged in or not. Some Limitations 1. No Migration of Virtual machine configured to use usb ports Based on the qm manual documentation (on the proxmox ve wiki), when you enable the hostusb option, you will basically grant direct access to the host hardware and thus make migration of virtual machines not possible.
If you have to use this option, keep that in mind. No concurrent access to the use usb ports In other words, this means that only one virtual machine at a time will have access to the usb device. If you have 2 virtual machines configured to use the usb port, both machine will see the device (within Windows Explorer) but only one will have the ownership of the device. Thus, only this virtual machine will be able to use the usb device. Supported Windows Operating System Family So far, we have seen that the usb pass-through is available and seems to work. However, you have to know that this functionality is working (and quite well actually) only with the following operating systems:. Windows XP (32/64 bit). Windows 2003 (32/64 bit).
Linuxdistribution (I’ve not test it yet but we assume that this is working) I’ve tried to perform the same configuration on a Windows 2008 R2 virtual machine and the results were not really satisfactory. The usb port is detected by the virtual machine but the usb device is never mounted in the virtual machine. I’ve got this error message: The device cannot start. (see screenshot below) Click to Enlarge picture This is for me a important limitations. If you are mainly working with “legacy” version of Windows Operating system, you are fine and you can use the out-of-the-box solution provided here.
If you are like me, you are exclusively working with Windows 2008 R2 (and coming new versions) and you cannot use this tip. To overcome this limitation, you can always try to use another option: USB over IP technology USB over IP Approach Usb over IP technology basically allows you to connect a usb device on a host machine and share it through your IP network.
Because the usb pass-through feature is not yet “ready to use”, Proxmox VE wiki web site is describing a way to implement USB over IP based on an partially free software. I have not tested it yet but if you are interested, you can have a detailed step by step procedure I’ve been testing another usb over IP option: the open source. I have downloaded and installed the software on a physical linux machine and start playing around with this utility. The tool is working as expected against windows 2003 operating systems. But again, big disappointment when trying from the Windows 2008 or later operating systems: it simply fails. Funny enough, the error message I’m receiving is exactly the same device cannot start.
USBIP project could provide a really interesting open source alternative for USB over IP technology. I hope that the project team will continue their work and make available soon a working and stable version of the software that will be compatible with Windows 2008 R2operating system.
Final Notes I’m kinda frustated now because yes, Proxmox VE can “out-of-the-box” use usb pass-through capabilities but only against Windows 2003 operating system. If you try with Windows 2008 and later, the usb device will not be accessible within your virtual machine. At the moment of writing, the only real alternative would be to use usb over IP technology. USBIP project could have been the way to go but the software is not really working with WIndows 2008 operating system Family. If you really need usb pass-through technology (whatever the operating system), you will need to invest some money and read provided by the Proxmox VE team Till next time See ya Sources:.
