Sorry, my fault.
Full URL is:

https://bugzilla.redhat.com/show_bug.cgi?id=492688

Problem is described there but for the lazy i copy-paste it here:

Virtual machine gets stuck after migration. One CPU is 100% load, other one
idles. The virtual machine could be pinged, ssh-login is not always possible.
If stopped on migration target and continued on migration-source the virtual
machine recovers after some time without load.

Version-Release number of selected component (if applicable):

kvm-84-1.el5.x86_64.rpm
kvm-kmod-84-1.el5.x86_64.rpm
qemu-0.9.1-11.el5.x86_64.rpm
qemu-img-0.9.1-11.el5.x86_64.rpm

kvm and kvm-kmod compiled from sourceforge sources and installed from built
rpm, qemu and qemu-img are from EPEL-repository

How reproducible:

Start a kvm-virtual-machine on host A, start a kvm-virtual-machine with the
same parameters on host B in incoming-Mode. Migrate the virtual-machine from
host A to host B. Watch the kvm-process go to 100% after migration finishs.
Maybe you have to wait up to 5 seconds or apply a ls or such in the virtual
machine. After stopping virtual machine on host B and continuing virtual
machine on host A the virtual machine recovers
