any random name. It has to be resolvable to an IP address
using DNS, and it is best if you give the fully-qualified

network is actually a separate physical network, or is done
using tunneling, etc. For performance reasons, it's
recommended to use a separate network, of course.
The <option>-b</option> option specifies the default bridge

The <option>-t</option> allows to set the hypervisor type of
the cluster. Available hypervisor types are: xen-3.0, fake and
<filename>/srv/ganeti/iso/hvm-install.iso</filename> because
instances created by the experimental HVM support require them.

+ This volume group must have the same name on all nodes.
