[Qemu-devel] [Bug 1318746] [NEW] qemu Windows 7 BSOD when using hv-time

2014-05-12 Thread Maik Broemme
Public bug reported: When I use hv-time sub option and run CPU-Z or 3DMark (Physics Test) the Windows 7 guest stops with BSOD (SYSTEM_SERVICE_EXCEPTION). It can be easily reproduced by running CPU-Z. It will fail every second or third time you execute CPU-Z and fail during PCI detection. If I

2014-02-05 Thread Maik Broemme
Hi, currently VFIO with multi GPU passthrough is working partially and hopefully somebody has a hint about the problem. I'm doing passthrough of an AMD Radeon R9 290X and AMD Radeon 7870 GHz Edition to a single VM. If the VM is running Linux this works quite well with radeon or fglrx driver.

Hi Alex, and what's the problem with q35/pc + vfio-pci (no x-vga). If vfio-pci is the direct replacement for pci-assign it must be a bug in vfio, huh? It's either a bug in vfio or the above configuration issue with the pcieport. I'd appreciate if you could advise how you're configuring
