[pve-devel] ahci unmigratable

yes, too late for 1.2.

I don't have tested ahci migration, But I think it should fail at the beginning of phase2, 
when when target vm will start, it will detect that the device is unmigratable.
So with the new migration code, the migration process will just stop and source vm will not be stopped.

I'll do some tests today to be sure.

Seems they already have a working version:

But so far they did not post the complete patch as no RFC.
