Server's unresponsive to the external world. It isn't dead, on two
occasions, when it happened at times like Sunday and 1am in the night,
I could afford to wait it out and see that it eventually does recover
from whatever it was.
It's almost definitely related to disk i/o due to the VM guest
fighting over the disks where their virtual disk-files are. However,
the hard part is figuring out the exact factors, I know CPU isn't an
issue having set up scripts to log top output when load goes above 5.
