CC'd to the mailing list, in case someone knows the answer

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

Guests are unaware of the network configuration in the host, e.g. the
bridge name. You should make sure the correct bridge name is set in 
the OVF file. virt_v2v script will handle that for you if you remove
the comments from the config file network section.
