Hi, I have Debian 10 VM under oVirt (HP ProLiant), with NextCloud/Collabora docker. VM is connected to external IP via 3rd Ethernet interface on ProLiant server to the switch/external IP link from ISP. VM doesn't have oVirt mgmt interface. Everything worked fine until my last upgrade which broke NextCloud, so I decided to restore recent backup copy, made with "Clone VM" from oVirt GUI. Now problem arises - network interface is not functional anymore at all, no traffic pass by. I deleted it, and created new one via Edit VM, updated /etc/network/interfaces on Debian, problem remains. ip a within VM shows no problems with networking, but even ping gateway IP and 8.8.8.8 doesn't work. I screenshot settings attached. Launching broken VM (which is a source clone of backup) shows no problems. Thanks in advance for any help. Andrei
