no reboot is required for guest networking, neither
host nor guest side

which is expected, as Linux-VServer uses IP isolation
instead of virtual network stacks (which you can get
by utilizing the network namespaces), so the guest
will always see a subset (according to the assigned
IPs) of the host devices and IPs

with this config, if you start the guest, util-vserver
will (according to your config) create an alias
'dummy0:virt0' with the ip 10.0.0.2/8 and assign that
address to your guest
