The host-side console message is "virtio_ioport_write: unexpected address 0x13 value 0x1". Eventually there are overlaps to bug #990364, but I'm not sure. Host machine: 2x Opteron 4238 a 6 cores, 32GB RAM, Linux x86_64 Guest machine(s): Windows 2008 Server R2 x64 I tried different combinations of component versions, but only kernel 2.6.34 could run the guests (but has other difficulties). See testet variants in comment. Run arguments are attached. Minidump follows immediately. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1014681/+subscriptions
