I have installed and configured VyOS as a VM on my Hyper-V host. It had configured firewall rules and Nat rules on 2 ethernet interfaces eth0 and eth1.
I have made a live migration of this VM between hosts, and now after rebooting this VM i lost configuration for my ethernet interfaces.
Command show interfaces now results with eth2 and eth3 interfaces without any configurations there.
How to “repair” this, and how to prevent this occure in future when moving running VyOS machine between host in a pool.
