# About brvirt
`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?"**
# Requirements
The script is compatible with `python2.7` and `python3+`.
- `brvirt` uses `virsh` tool to list VM properties and virtual network interfaces. To install `virsh` 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](https://bitbucket.org/astanin/python-tabulate) python package to render console tables:
```shell
TABULATE_INSTALL=lib-only pip install tabulate
```
# Usage
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
