Hash: SHA1
Package: libvirt-bin
Version: 0.6.1-1
Severity: important
I labeled this patch important because after upgrading you are unable to
start any virtual machine that has a kernel compiled for 64-bit. So it
will bring down any set of virtual machines using this package, kvm, and
64 bit kernels.
The patch is located here:
http://permalink.gmane.org/gmane.comp.emulators.libvirt/12544
Debian only applied the first patch, and not the second as well.
As you can see libvirt only detects the 686 for the kvm, and not the
x86_64.
Here is some output from my server:
root at physical-1:/var/nfs/kvm# kvm -cpu '?'

x86 486
