I continued runnign previous kernel (3.1.9...) and a w7 spiced guest.
This morning after reboot it seems w7 guest doesn't start anymore.
It remains in the black screen with w7 logo that flash a little and
remains there with 100% cpu consumption...
ALso trying to rstart with old kernel after this the w7 guest blocks
its startup...

Any suggestion or other guys encountering such a problem?
