Example 4.13. Get the domain info

# Example-50.py
#!/usr/bin/env python3
import sys
import libvirt
from xml.dom import minidom

domName = 'CentOS7'

conn = None
try:
    conn = libvirt.open("qemu:///system")
except libvirt.libvirtError as e:
    print(repr(e), file=sys.stderr)
    exit(1)

dom = None
try:
    dom = conn.lookupByName(domName)
except libvirt.libvirtError as e:
    print(repr(e), file=sys.stderr)
    exit(1)

state, maxmem, mem, cpus, cput = dom.info()
print('The state is ' + str(state))
print('The max memory is ' + str(maxmem))
print('The memory is ' + str(mem))
print('The number of cpus is ' + str(cpus))
print('The cpu time is ' + str(cput))

conn.close()
exit(0)
