Find your vm's IP with virsh and

Basically use virsh commands to get the VMs' MAC address first and then use arp to get the IPs.

$ virsh domiflist $DOM
$ arp -i $BRIDGE

For example:

$ virsh list --all
 Id    Name                           State
----------------------------------------------------
 2     suse_13_2                      running

$ virsh domiflist suse_13_2
Interface  Type       Source     Model       MAC

$ arp -i virbr0
