[CentOS-devel] another 6.4 gotcha

something changed in the kvm audio subsystem, so a virt that was 
suspended during shutdown wouldn't resume after reboot. the logs had 
complaints of:

savevm: unsupported version 2 for 'hda-audio' v1
load of migration failed

i poked around on the rh bz site and found a few hits, but they seemed 
to be related to older versions. i forced a clean boot of my vm and it 
was happy.
