It's definitely some kind of Disk IO problem, I can't even copy a 700MB file
on that guest without waiting a loooong time. Running bonnie on my linux
guest shows considerable slow down in disk performance.
Results after a fresh Reboot of the Host:

After a reboot of the host, they guest are fine again, but for how long...
Any advice or suggestions?
