'Proxmox - migration fails with exit code 255
Attempting to migrate a container between Proxmox nodes failed saying the following command failed with exit code 255:
TASK ERROR: command '/usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=violet' [email protected] pvecm mtunnel -migration_network 172.20.20.1/16 -get_migration_ip' failed: exit code 255
Running the command manually shows the given error message:
could not get migration ip: multiple, different, IP address configured for network 172.20.20.1/16
Solution 1:[1]
Turns out, I had a second interface on the target host configured on the same network (eno1 had 172.20.0.1 and eno3 had 172.20.20.3, e.g.). Removing/disabling one of these interfaces resolved the issue.
