Hello List, Has anyone performed VGA Passthrough with a Radeon 6990 card? Secondary to that, has anyone done a crossfire setup on an HVM DomU? I''d like to run Xen on top of my desktop and put Windows into a VM, shuffling my setup around a little bit, but I''d really like to get the full VGA BIOS support that passthrough offers. Thanks, Andrew Bobulsky

Hello List, I have a system that came with an OEM copy of Windows 8, and I want to virtualize that same copy of Windows on top of Xen. While I''ve done this with retail copies before, that''s just a matter of a license key. BIOS SLICs, while convenient, are likely less straightforward to translate into a VM. Does anyone know if this is possible and/or supported by Xen/QEMU?

Hello List! As I venture a little further down the Xen rabbit hole, I''ve gotten myself wondering: could I script the use of "xm pci-attach" and "xm pci-detach" such that I can shift all of my difficult-to-virtualize PCI devices, such as video card[s], USB controllers, audio devices, and so on, from one running DomU to another? Give myself a button or key

Hi, I am new to Xen and I was wondering if the following construction would be feasible with the current Xen. I would like to put 2/3/4 new computers in my house, mainly for gaming. Instead of buying 2/3/4 different computers, I was thinking of building one computer with a 4/6/8-core CPU, 2/3/4 GPUs, 2/3/4 small SSDs, and attach 2/3/4 monitors to it, 2/3/4 keyboards and 2/3/4 mouses, and run VGA

I guess I have stumbled upon a bug in gplpv drivers. If you try to re-enable an nic adapter after disabling it, it just hides out of blue. And you have to reboot. Latest version of gplpv drivers and Windows 2008 R2 here. Anyone else noticed the same issue? I wonder if this is related to hot-plugging something like

Hello, Like many trying and posting here, I''m new to VGA passthrough. Computer was bought, checking compatibility from http://wiki.xen.org/wiki/VTd_HowTo The hardware is mostly not exactly on the list, but mainly new versions of the same series (I think). IOMMU "seems" to be working (not 100% sure what to check). I used debian/wheezy kernel and xen, dom0 and HVM domu.

Hi, I''m trying to get VGA passthrough to work to an XP x64 guest, and I''m seeing "interesting" things happening. I''m using the kernel and userspace tools from here: http://xen.crc.id.au/support/guides/install/# on Scientific Linux 6. I gave up on trying to get an Nvidia card to work in the guest having read about the extra patches required to get a

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

Hey, Are there any known issues with the Intel''s integrated HD graphics 4000? I just bought a new laptop and have tried everything I can think of to get Xen to load. After choosing Xen in GRUB, it just boots to a black screen. There is no error message , no dmesg output, nothing. I have no idea what is causing this problem. I''ve gotten Xen to install with no problems on another
