Is there any chance that you can try upstream qemu-kvm? I tried running qemu-kvm from git but it exhibited the same problem as 12.x that I tried before, BSODing once in a while, running kernel 2.6.34.1. sample BSOD failure details: These two with Realtec nic and qemu cpu 0x00000019 (0x0000000000000020, 0xfffff88007e65970, 0xfffff88007e65990, 0x000000000502040f) 0x00000019 (0x0000000000000020, 0xfffff88007a414c0, 0xfffff88007a414e0, 0x000000000502044c) These are with e1000 and -cpu host 0x0000003b (0x00000000c0000005, 0xfffff80001c5d842, 0xfffffa60093ddb70, 0x0000000000000000) 0x0000003b (0x00000000c0000005, 0xfffff80001cb8842, 0xfffffa600c94ab70, 0x0000000000000000) 0x0000000a (0x0000000000000080, 0x000000000000000c, 0x0000000000000001, 0xfffff80001cadefd) I'll see if I can analyze minidumps later. In addition to these there have been as many reboots that have been only logged as 'disruptive shutdown'. Right now I'm running the problematic guest under Xen 3.2.1-something from Debian to see if it works better. -- Harri.
