Remote migrate error - Insecure dependency in unlink

[jkatz]

I'm trying to migrate a vm from one cluster to another. The call gets accepted and a 'Migrate' task gets created on the source. It does error out with 'Error: migration problems' A qmtunnel does get created on the target cluster. It spins for a moment and then stops with status=ok.

I checked the task log in the source and get this message:

2024-10-21 20:52:51 Setting up tunnel for '/run/qemu-server/101.migrate'
2024-10-21 20:52:51 ERROR: online migrate failure - failed to write forwarding command - Insecure dependency in unlink while running with -T switch at /usr/share/perl5/PVE/Tunnel.pm line 214, <GEN9693> line 5.
2024-10-21 20:52:51 aborting phase 2 - cleanup resources

If I try it with the VM powered off, then the error message is: 'Error: migration aborted'. Same log entry.

Any idea where to go from here?

Thanks,
jonathan

Hi,
thank you for the report! This should be fixed in git: https://git.proxmox.com/?p=qemu-server.git;a=commit;h=ea4c1ccb2ccc1e2a83f2bd6f28759b76faa19b23
but is not part of any released package yet.

A workaround should be using the CLI command via qm remote-migrate directly.

@fiona did this patch not make it into v1.0.1? or am I experiencing a new issue?

Hi @b3nw ,
the fix was applied long ago. It does not depend on the PDM version, but the Proxmox VE version. Make sure your qemu-server package version is at least 8.2.5 on the source node of the migration. You can check with pveversion -v for example.

If the version is new enough, please share more details about your issue, i.e. full task log, versions from source and target node, VM configuration.
