# Troubleshooting

## Network Issues
To be able to debug early network issues in the boot process the 2 test VMs lxdev04 and lxdev05 have network port mirroring enabled.

I.e. lxdev04 has a second interface that mirrors the primary interface of lxdev05 and lxdev05 has a second interface that mirrors the primary interface of lxdev04.

Bring the device up without IP address:

```
ip link set dev ens192 up
ip addr flush dev ens192
```
and then use `tcpdump -i ens192 ...`
