Hi Mike,

yes that´s one of the advantages of virtualisation, your guest system is
more or less independent from your physical machine. Yes of course if you
restart your pohysical machine your guest will also be rebooted.

You a connection between host and guest through the network bridges. Your
guest system are indepeendent because the have their own virtual harddisc
and no dierect r/w access to your host os.

What kind of cluster do you want to build?
