Not sure if this is related but this is what happens on my system when I
try to do a live migration with kvm-88 and the latest kernel 2.6.30
(gentoo 2.6.30-gentoo-r5).

This is the sysexit instruction.
Are you doing cross-vendor migration (AMD->Intel or vice versa)?
This is supported in kvm-88, but not in previous versions. Are you sure the
kvm-88 modules are loaded on the target host, and not the modules that came
with the kernel?
Try 'cat /sys/module/kvm/version'.
Only AMD->AMD, all of them are at kvm-kmod-devel-88
All of them run the userspace with kvm-88
Migration works if I do it with a live cd, but not if I do it with a
running machine.
Each guest only has 1 cpu, 2 nics (I tried both virtio and e1000),
I tried with both 2.6.29 and 2.6.30
2.6.29 was a known working with kvm-84.
