Since I am kind of an idiot and don't know what I am doing...I am having
trouble with getting network stats to work in Python. I have everything
correct...but I am just not sure exactly what it is looking for. I get this
error:
libvir: Xen error : invalid argument in xenHypervisorDomainInterfaceStats:
invalid path, should be vif<domid>.<n>.
I guess I just need some kind of example to work from on this.

As described in the error message, try setting the path to something
like "vif1.0" where 1 is the domain ID and 0 is the interface number.
You can enumerate interfaces available by dumping the domain XML.

virt-p2v converts physical machines to virtual machines. Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.

When I pull out network stats...it just gives me a tuple. Is there any
documentation on what this is actually displaying so I can format
accordingly?

I'm assuming this is the python bindings, in which case the tuple has
these fields:
http://libvir.org/html/libvirt-libvirt.html#virDomainInterfaceStatsStruct
rx = receive, tx = transmit
A value of -1 in any field means no data is available.

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