CPU time and memory use appear to be tied to the size of 
/var/log/messages.  This really sucked for me when I turned on NFS 
debugging (my F11 workstation's NFS mounted /home keeps hanging) and I 
ended up with several GB of logs.  It looked like kerneloops loaded all 
of its contents into RAM.  IIRC, that problem went away when I forced 
the rotation of my logs.

 From Virtual Machine Manager, double click on your VM.  Click on the 
"Details" tab, select "Sound: ..." and then click the "Remove" button in 
the lower right.  This isn't a regression, AFAIK.  VMs have always had 
exclusive access to sound if you leave that device configured.
