Pre/Post-Migration Hookscripts - any status updates?

[lclements0]

Looking through the forums here, it looks like some commit work took place to enable pre/post-migration hookscripts some time back in late 2022. Looking at a recent PVE 8.2 installation, however, it appears that these hooks are still not present in the QemuMigration.pm or CLI qm source files on the hosts.

Are there plans to finish and integrate this work at some point in the near future?

I've got a need to be notified when migrations occur across a PVE datacenter I help manage, and am looking at options that don't involve consistently patching after updating the underlying PVE install.

Thanks!

You should be able to do this via the start hookscript by checking the PVE_MIGRATED_FROM environment variable. It is set when the started VM has been migrated from another node.

Hey Shanreich,

This works well on machines that are started/booted, but doesn't (for obvious reasons) trigger on an offline migration, for instance.

When building a system that integrates with the Proxmox API to gather status details on the VM's themselves, maintaining the Proxmox node correctly in the remote application avoids having to do looped lookups for the VM on a failure.

Having a hook that kicks off during an online/offline migration would be a huge help.
