I set up a CentOS 6.4 x64. Fired up a Windows Server 2003 x64 guest and the second I installed the virtio drivers, I got a BSOD with 0x00000007e (a different error, yes, but won't boot until I yank the viostor.sys file). This is on completely different hardware and it's a qcow2 rather than a raw image, so at this point I have to believe that there is something very broken in the virtio drivers. I'm thinking at this time because I need these guests running in a production environment that I'm going to go back to an earlier Debian release. I' m pretty disappointed here. KVM has been rock solid for me for two years, and this is the first trouble I've had. -- Aaron Clausen mightymartianca@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
