{Guide} Create a Gaming Virtual Machine - Page 5

post #41 of 813
Thank you very much for your thorough, helpful answer! thumb.gif

I'm staying with tried and true Sandy Bridge for now: Q67 + i5 2500. Mostly because finding a micro-ATX motherboard with VT-d (for certain) isn't easy. I found the Intel DQ67SW and the Gigabyte GA-Q67M-D2H-B3, as they clearly state the feature as present in their specs page or the manual.

Do you know if the GTX 680 works via IOMMU in Xen? Same question for the 580?

There are patches to enable support, but I am not sure which ones are needed and there are several that have been proposed. I am working (slowly) on getting a patched install .iso for you Nvidia users. Hopefully within a week I will have a more streamlined guide and within a month the patches and scripts will be available as well. ASrock H67 and some Z68/Z77 boards also have it.

I am always glad to help smile.gif

Thanks for the motherboard suggestions. In the end, I bought the Gigabyte Q67.

Regarding the graphics card, I decided to play safe and go with an AMD (ASUS 7970 DCII) after seeing your comment, and given the need for flimsy patches and headaches, with nVidia cards.

It's very kind of you to put the effort into creating a turn-key solution for setting up a gaming VM. Personally, I don't like binary / generic solutions so I don't think I'll use it. I always compile packages from scratch and run hand-optimized kernels (Gentoo Linux distribution)... One has to satisfy their OCD biggrin.gif. Plus, Xen is part of the mainline kernel as of v2.6.39 which is fantastic. That way, we can always run the very latest kernel. I would gladly contribute to your project if there's any way I can help, though.

Yeah that is cool! I almost went the KVM route for this guide (and my home system) but the Xen Hypervisor is a lot more efficient. Look at the CPU score thumbsdownsmileyanim.gif On Xen that would be at least a 7.6 on WEI. I know it's not the best benchmark, but ken does a lot better job with resources. The process looks a lot easier with KVM -- well at least until I get my Xen USB stick working.

Speaking of that, do you know how to get a proper grub2 bootloader on a fredora spin? I assume I would have to modify the plymouth initrd.gz.

What score are you talking about? I'm sorry, I don't follow.

Recently, I read this article and thought Xen was on par with KVM. Have you tried KVM yet, to compare?

Doesn't Fedora 16 already install GRUB 2?

If so, you can perform a regular install of Fedora with the stick as the target. It will create partitions and install GRUB.

Or, install on another media and when you achieved a final version, manually partition the stick, mount them in, say, /mnt/usb, use grub-install on the USB device node (/dev/sdX) like you would on a regular hard disk and then "(cd / && tar cp) | (cd /mnt/usb && tar x)".

I can't go into further details for now as I don't have a proper PC to experiment on while waiting for parts.

I have read articles that also say Xen is a lot slower. There were even some that showed Xen on top. That review is also outdated and is still on Xen 3.x while the current Xen release is 4.1.2 You also have to keep in mind that Xen is a type 1 hypervisor and KVM is a type 2. In general, type 1 are more efficient and give better results when used properly. Xen also does Paravirtual machines better than KVM if I recall. I know that WEI isn't the best benchmark, but it still measures the CPU and all I know is that what I saw was a lower CPU score than mine (using the same processor).

Moving on to Grub2... The problem is that I want the .iso to include the proper boot loader so that anyone can use this technology. I could get it working for myself, but I want it to be ready for anyone to download the .iso, use the utility to put it on a USB stick and just boot it. I Think the key is in the fedora spin's .ks file. There is most likely a way to script it to use a full-featured boot loader in the boot image rather than the stock fedora live version.

I'm not sure about a full listing, but I know that most ASrock 1155 boards offer it. The best way is to download a copy of the manual and just search for VT-d in the PDF.

Great guide! Thanks for all the work putting it together. I'm so close that I can almost taste success, but as of yet I have been unable to get the VM to start with the GPU attached. I'm able to get to the point where 'xm pci-list-assignable-devices' shows the devices I'm wanting to assign to the guest, but every time I try starting the VM I get an error saying "Error: pci: PCI Backend and pci-stub don't own device xxxx:xx:xx.x".

I've tried using both pci-stub and xen-pciback, but am still met with the same error. I can confirm with lspci that they are in fact owned by pci-stub or pciback. Any ideas?

MB: Asus Crosshair Formula V
CPU: FX-8120
dom0 GPU: GTX 280
domU GPU: GTX 590
OS: Fedora 16
Xen: 4.1.2

I've also tried giving the 280 to domU, thinking that there might be issues with dual GPU cards, but I still get the same error.
