[pve-devel] Local Disk Migration and ide controller

[Emmanuel Kasper]

Hi Alexandre

When migrating local disks and ide I get the following error:

drive-ide0: transferred: 52428800 bytes remaining: 0 bytes total:
52428800 bytes progression: 100.00 % busy: 0 ready: 1
all mirroring jobs are ready

TASK ERROR: migration problems

I presume this comes from QemuMigrate.pm

# remove drives referencing the nbd server from source
# otherwise vm_stop might hang later on
foreach my $drive (keys %{$self->{target_drive}}){
		PVE::QemuServer::vm_mon_cmd_nocheck($vmid, "device_del", id => $drive);
}

What should we do with VMs on disks IDE bus ? I can prepare a patch to
catch this before the migration starts or do you see any better option ?

I would like to iron out these kind of errors before putting the Migrate
Local Disks option in the GUI.
