brvirt
displays bridges and enclosed interfaces along with corresponding
KVM Virtual Machines names and virsh domain ids.
It answers one simple question: How to determine which virtual interface belongs to which virtual machine and what bridge it is in?"
The script is compatible with python2.7
and python3+
.
brvirt
usesvirsh
tool to list VM properties and virtual network interfaces. To installvirsh
use:
# on Debian-based distros:
sudo apt-get install libvirt-bin
# on RHEL based:
sudo yum install libvirt
- Apart from virsh, the script relies on tabulate python package to render console tables:
TABULATE_INSTALL=lib-only pip install tabulate
As simple as python brvirt.py
will produce the following output which combines brctl
and virsh domiflist
commands output:
(brvirt) [root@leo ~]# python brvirt.py
