Until recently, I was using the VirtIO drivers from RHEV 2.2, which don't suffer from this problem. As of Fedora 16, however, that isn't an option, because they cause the guest to blue-screen early in the boot process. So ... I've been doing some more testing with the following setup: Host: Intel DQ67SW motherboard with Q67 chipset (including IOMMU) BIOS version SWQ6710H.86A.0050.2011.0401.1409 (release date 04/01/2011) Intel Core i7 2600, 4-cores, 8 threads, 3.4 GHz 16GB memory Fedora 15 64-bit, fully updated including updates-testing repo qemu-kvm-0.14.0-8.fc15.x86_64 libvirt-0.8.8-7.fc15.x86_64 kernel-2.6.41.6-1.fc15.x86_64 Guest: Windows 7 Professional 32-bit, fully updated 2 VCPUs 3.5GB memory Red Hat VirtIO Ethernet Adapter driver version 6.0.209.605 (9/20/2010) Red Hat VirtIO SCSI Controller driver version 6.0.0.10 (9/20/2010) (No VirtIO serial ports or channels defined) (The VirtIO drivers are from http://alt.fedoraproject.org/pub/alt /virtio-win/latest/images/.) I have determined that disabling the Intel IOMMU has no effect; the problem still occurs. Perhaps more interestingly, it seems that the problem only occurs when I am using the VirtIO SCSI *and* the VirtIO Ethernet drivers. It seems that the problem does not occur if I only use one of the drivers; an IDE disk with a VirtIO NIC seems to be stable, as does a VirtIO disk with an e1000 NIC. Now to the big question ... what the heck can be done to get this problem f= ixed? I hope that everyone agrees that it's totally unacceptable for a pro= blem like this to sit unfixed for so long. I am more than willing to test = any patches, enable debugging, etc.; just tell me what to do.
