I am really excited to start using this, but I have a couple of
questions
about how to use it exactly. I want to be able to pull a list of stats out
of my Xen machines. I need to get something like network i/o. I just need
to know how much in and out traffic that a specific machine is doing. I am
pretty new to python and to programming in general. I have looked at the
APi and stuff like that, but am a little confused still on how to actually
do this. Mainly I just need to know how to connect to certain things.
You can actually just do this directly with virt-top:
virt-top -csv file.csv
You'll get a new line of stats in the CSV file every (by default) 3
seconds, and if you look at the "Net RXBY" and "Net TXBY" columns for
each domain that will tell you bytes received and bytes sent in that 3
second period. You can also feed the CSV output into a pipe and
process it using another program in real time.

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