Hi all,
It's been a while and I have been doing tests in the background.
I found some issues were related to faulty drives, but after removing
them migration issues continued. I had the same issues with PVE 3.2,
nfs, rbd and local storage.
I also noticed that out office production cluster doesn't seem to suffer
this problem (PVE 3.3) .
Today I found this post on the forum:
http://forum.proxmox.com/threads/19733-storage-migration-virtio-failed
Short is that in /usr/share/perl5/PVE/QemuServer.pm
changing:
---
if ($vmiddst == $vmid) {
# switch the disk if source and destination are on the same
guest
vm_mon_cmd($vmid, "block-job-complete", device =>
"drive-$drive");
}
---
with
---
if ($vmiddst == $vmid) {
sleep 10;
# switch the disk if source and destination are on the same
guest
vm_mon_cmd($vmid, "block-job-complete", device =>
"drive-$drive");
}
---
So adding a sleep, seems to have fixed all the migration problems so far
(I continue testing while I write this email).
The problem seems related to performance. The problem-suffering cluster
has 3 nodes each with 1 desktop CPU, 2 GB RAM, 2 relatively old hard
disks (~60MB/s write on NFS). Network is 1x1Gbit on each node, all on
the same HP 1gbit switch.
Although a work-around, maybe putting a sleep 1 could help some users
while not being noticeable for the rest?
Cheers

Just tried moving a VM WS2008R2 with virtio v74 from local storage to
NFS (2 different servers) and RBD, all failed.
Does anyone with PVE 3.3 have working online storage migration with
Windows guests and virtio?
Thanks

I have tried with virtio v74, but it also fails. All failures so far
with WS2012R2, Debian8beta2 works ok. I'm trying with WS2008R2 now.

I think problem is windows virtio v81. Debian 8beta has worked ok; I
will do further tests on monday.

Yes doing it with VM off works, but I can't make it work
with VMs on. It used to work in 3.2 and before, something
must be broken.

In some cases the same, migrating a hard drive from a

I fix this turning off the vm

Hi all,
I tried local to RBD storage migration with VM running,
and it fails like it does with NFS:
transferred: 53687091200 bytes remaining: 0 bytes
total: 53687091200 bytes progression: 100.00 %
Removing all snapshots: 100% complete...done.
image has watchers - not removing
Removing image: 0% complete...failed.
rbd: error: image still has watchers
TASK ERROR: storage migration failed: mirroring error:
VM 103 qmp command 'block-job-complete' failed - The
active block job for device 'drive-virtio0' cannot be
completed
I noticed that during migration HTML5 console's key
drop-down menu doesn't work (VM doesn't receive keys).
