⁠7.3.4. Retrieving Interface Network Addresses

You may find yourself with a virDomain instance, and need the IP addresses of one or more guest domain interfaces. The interfaceAddresses method provides this capability.

Example 7.11. Fetching the IP addresses of all the guest domain network interfaces

# Example-14.py
#!/usr/bin/env python3
import sys
import libvirt

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

domainName = 'CentOS7'
dom = conn.lookupByName(domainName)
if dom == None:
    print('Failed to get the domain object', file=sys.stderr)

ifaces = dom.interfaceAddresses(libvirt.VIR_DOMAIN_INTERFACE_ADDRESSES_SRC_AGENT, 0)

print("The interface IP addresses:")
for (name, val) in ifaces.iteritems():
    if val['addrs']:
        for ipaddr in val['addrs']:
            if ipaddr['type'] == libvirt.VIR_IP_ADDR_TYPE_IPV4:
                print(ipaddr['addr'] + " VIR_IP_ADDR_TYPE_IPV4")
            elif ipaddr['type'] == libvirt.VIR_IP_ADDR_TYPE_IPV6:
                print(ipaddr['addr'] + " VIR_IP_ADDR_TYPE_IPV6")

conn.close()
exit(0)
