New network card "Device instance id" after VM restore

[n1kt0]

Hei!

Problem.
After the old server died, I restored the virtual machine, but the network didn't work!
It turned out the machine's old network card had disappeared and a new one had appeared.

Since the IP address was set manually, the network didn't work.

Old "Red Hat VirtIO Ethernet Adapter"
PCI\VEN_1AF4&DEV_1000&SUBSYS_00011AF4&REV_00\5&97B8697&0&9008F0

Device instance id: 5&97B8697&0&9008F0

New "Red Hat VirtIO Ethernet Adapter #2"
PCI\VEN_1AF4&DEV_1000&SUBSYS_00011AF4&REV_00\5&2490727A&0&9008F0

Device instance id: 5&2490727A&0&9008F0

Question: Is it possible to return the old card and lock it so that the ID is always 5&97B8697&0&9008F0?

Hi,
please share the output of pveversion -v and qm config ID with the numerical ID of your VM as well as the config inside the backup, i.e. Show Configuration button when selecting the backup.
