This update has broken my existing Windows XP Guests.
The machines bluescreen on boot with a 0x0000007E in ACPI.SYS.

Manually reverting to the previous bios.bin from commit 01afdadc92e71e29700e64f3a5f42c1c543e3cf9
dated Aug-7 allows them to boot normally.

The VM's were created many moons ago using qemu-kvm which I upgraded to qemu vanilla yesterday.

I used to boot them with qemu -net nic,model=virtio -net tap,ifname=tap0,script= -drive 
file=/tracks/nobackup/xp_office.qcow2,cache=unsafe -m 512 -localtime
And now I just add the -enable-kvm to the existing command line.

Host is a core2duo running a 64 bit vanilla 3.7-rc6 kernel and a 32 bit debian userspace.

Not a huge issue and certainly not urgent, but one I'd like to nail down before I go migrating my 
production boxes from qemu-kvm to qemu vanilla.
