[SOLVED] Live migration bug during upgrade to PVE 7.3

[bfwdd]

Hi,

we're are having a serious issues with live migration during upgrade to PVE 7.3
Our cluster is a 15 node cluster with external Ceph storage (no HA configured)

Since 4 years we are updating our cluster with an ansible script: (Upgrade packages on host, migrate vms to spare host, reboot and migrate back)

But today all VMs (2x Debian Linux & 2x WIN2012) got stuck with this error:
2022-11-24 15:58:13 start migrate command to tcp:10.40.0.66:60000
2022-11-24 15:58:14 migration active, transferred 52.5 MiB of 8.0 GiB VM-state, 6.4 GiB/s
2022-11-24 15:58:15 average migration speed: 4.0 GiB/s - downtime 119 ms
2022-11-24 15:58:15 migration status: completed
RTNETLINK answers: Operation not supported
2022-11-24 15:58:15 ERROR: tunnel replied 'ERR: resume failed - command '/sbin/bridge fdb append 5E:3C:C0:F3:E0:37 dev tap409i1 master static' failed: exit code 255' to command 'resume 409'
2022-11-24 15:58:19 ERROR: migration finished with problems (duration 00:00:12)
TASK ERROR: migration problems

VM on new host is paused and resume task is failing:

RTNETLINK answers: Operation not supported
TASK ERROR: command '/sbin/bridge fdb append 6A:41:31:8F:4C:18 dev tap409i0 master static' failed: exit code 255

I had to unlock vm, kill the kvm process on both hosts and start them again.

We are using OVSBridge.


I hope somebody can help

Kind regards,
Konrad

do you have same problem if you try to start the vm on the 7.3 node ?

This bug was already fixed
https://git.proxmox.com/?p=pve-common.git;a=commit;h=99fc81231e09febc4ed9bdbae8a87eca73b0dc3e

but I think it's not released in the pve-common package

Can you please try libpve-common-perl in version 7.3-1? Just uploaded to the pvetest repository.
