Bug description:
I use eucalyptus software (1.6.2) on debian squeeze with kvm 0.12.4+dfsg-1.
Kernel 2.6.32-3-amd64. After a few days machines crash. There are no logs in
host system. Guest is the same kernel and OS as host. The kvm process use 100%
of cpu time. I can not even ping the guest. Here is the log from virtual
machine:
