HI,

I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information.

Here is my simple code:

#!/usr/local/bin/python

import

libvirt

import

sys

conn = libvirt.openReadOnly(

None)

conn == None:

print 'Failed to open connection to the hypervisor'

sys.exit(

try

domIds = conn.listDomainsID()

for id in domIds:

dom0 = conn.lookupByID(id)

dom0.info()

print "Domain 0: id %d running %s" % (dom0.ID(), dom0.OSType())

print dom0.info()

except:

print 'Failed to find the main domain'

sys.exit(

)

The output is :

Domain 0: id 2 running hvm
[1, 131072L, 131072L, 1, 14921710000000L]
Domain 0: id 3 running hvm
[1, 131072L, 131072L, 1, 30880000000L]

Here I am not able to understand these values are represent what type of information, which value is representing what resource of host machine.Could you please help me to understand how I could find out CPU,VM ,memory related information seperately through python binding?.

I didn't find Python binding Reference in the Libvirt site.Could you help me by providing the Reference link for Python binding?

Thanks in Advance!!
