One work around would be to pass through a dedicated NIC. Somehow Windows "looses" the DNS server, or access to it. This is most likely a networking issue with the bridge, though I haven't figured out what exactly. I) Youtube video stops after a few seconds, hangs for a while, and continues, just to stop again after a few seconds. Everything except the following two issues work as if I was running Windows directly on the hardware.

I use a SAMBA share under Linux to copy files between the two.Ĭan you confirm your Windows 7 installation behaves as native?ĩ5% yes.
Right now I switch from one to the other via KVM button and the input selector on my screen, but if I have to go forth and back a lot I run a remote desktop in Windows to connect to my Linux dom0, or vice versa.

I could hook up two screens, keyboards and mice and two people would be able to use it at the same time, with full video acceleration on both. I've written a how-to for Linux Mint 13/14, which should likewise work with Ubuntu 12.04 and 12.10. If your hardware doesn't meet the above, either replace the incompatible part, or forget the whole thing! It is MUCH easier if you have two graphics cards, or a CPU internal GPU (like on most new Intel desktop CPUs) and a discrete graphics card for passthrough.One will serve Linux, the other your Windows guest. The newer Xen 4.2 hypervisor supposedly improves graphics cards compatibility, though I haven't tried it. There are some more Nvidia graphics adapters that work, but first check the links above if it's listed. In general, most modern AMD (ATI) graphics cards will work, but it's best to check here and Some Nvidia graphics adapters are also supported, namely the Quadro series of "Multi-OS" capable cards starting with the Quadro 2000 model upwards (the Quadro 600 for example isn't specified as "Multi-OS"). A graphics card that supports VGA passthrough. In some cases there is no way going back to the earlier BIOS that does support it. I'm not joking here, one BIOS release may support VT-d, the next one doesn't.
See the Wikipedia link above, as well as and. CPU with VT-d (Intel) or AMD-Vi (AMD) support. My goal was to get fast switching on 2 desktops, the way you would have 2 full OSes booted simultaneously.Ĭan you confirm your Windows 7 installation behaves as native? What about other peripherals? Scanner, printer, gamepad, etc.? I know that to get it working you need hardware that supports both VT-x and VT-d. I once tried to setup a xen virtualization with Linux as Host and Win7 as guest with VGA passthrough, because I believed that I can get 99%+ native performace.Īt the time tough it was very new and undocumented, so I gave up on it.
