Dear All,
We've exported some VMs from our old oVirt infrastructure and want to import them into
the new one, but qemu-img appears to be failing. We have mounted an export domain
populated from the old oVirt in the new hosted engine and are using the GUI to import the
VM. Manually running the command sits at 16% CPU, 0% network usage and no progress. It
appears to lock the NFS mount and ls and lsof both hang.
sudo -u vdsm /usr/bin/qemu-img convert -p -t none -T none -f raw <path to source> -O
raw <path to dest>
Conversely a simple cp will work (ruling out file permissions errors):
sudo -u vddm cp <path to source> <path to test>
What might we be doing wrong?
Regards,
Callum

Dear All,
It would seem this is a bug in 4.3.? - As upgrading the old oVirt HE to 4.3 (from
4.2.latest) now means that the export of VMs to export domain no longer works.
Again qemu-img convert is using some cpu, but no network. Progress is 0.

Dear All,
Further to this, I can't migrate a disk to different storage using the GUI. Both disks
are configured identically and on the same physical NFS provider.

to do with moving a disk to/from a share.

Dear Benny,
It would seem that even cloning a VM is failing, creating a VM works on the same storage.
This is the only error i could find:

It's the qemu-img convert for sure that's just failing to do anything, this is the
command from the clone:

gdb has a blank output for this though. This means 4.3.2 is fairly unusable for us, so two
questions, can I downgrade to 4.2, and is there a fix coming in 4.3.3 for this?
Regards,
Callum

gdb has a blank output for this though. This means 4.3.2 is fairly unusable for us, so two

Dear Benny and others,
So it seems I wasn’t being patient with GDB and it does show me some output. This error of
qemu-img convert even is failing and preventing updating ovirt-node version from 4.3.2 to
4.3.3.1. I get a feeling this is an unrelated error, but I thought I’d be complete:
Excuse any typos, im having to type this manually from a remote session, but the error:
[733272.427922] hid-generic 0003:0624:0249.0001: usb_submit_urb(ctrl) failed: -19
If this bug is preventing even a local yum updatei can’t see how it’s any issue other than
somehow involved with the hardware of the hypervisor, our network and storage
configuration must be irrelevant to this fact at this stage?
Regards,
Callum

It's the qemu-img convert for sure that's just failing to do anything, this is the

gdb has a blank output for this though. This means 4.3.2 is fairly unusable for us, so two
questions, can I downgrade to 4.2, and is there a fix coming in 4.3.3 for this?

Callum

It would seem this is a bug in 4.3.? - As upgrading the old oVirt HE to 4.3 (from
4.2.latest) now means that the export of VMs to export domain no longer works.
Again qemu-img convert is using some cpu, but no network. Progress is 0.

Dear All,
We've exported some VMs from our old oVirt infrastructure and want to import them into
the new one, but qemu-img appears to be failing. We have mounted an export domain
populated from the old oVirt in the new hosted engine and are using the GUI to import the
VM. Manually running the command sits at 16% CPU, 0% network usage and no progress. It
appears to lock the NFS mount and ls and lsof both hang.
sudo -u vdsm /usr/bin/qemu-img convert -p -t none -T none -f raw <path to source> -O
raw <path to dest>
Conversely a simple cp will work (ruling out file permissions errors):
sudo -u vddm cp <path to source> <path to test>
What might we be doing wrong?

Sorry, I kind of lost track of what the problem is
The "KeyError: 'appsList'" issue is a known bug[1]
If a manual (not via vdsm) run of qemu-img is actually stuck, then
let's involve the qemu-discuss list, with the version of the relevant
packages (qemu, qemu-img, kernel, your distro) and the output of gdb
commands

Dear Benny,
This is via VDSM, but a manual one fails too.
Background: cloning of an image fails in any context, whether creating from template,
using Clone VM, etc etc. Tested on any 4.3+ on multiple NFS servers etc. Even tried
allowing root access and not, seems to not fix.
gdb is blank and has no relevant output
/var/log/messages
Appear to be getting this regularly ~5mins:

I tried to filter the usual noise out of VDSM.log so hopefully this is the relevant bit
you need - let me know if the full thing would help.

Sorry, I kind of lost track of what the problem is
The "KeyError: 'appsList'" issue is a known bug[1]
If a manual (not via vdsm) run of qemu-img is actually stuck, then
let's involve the qemu-discuss list, with the version of the relevant
packages (qemu, qemu-img, kernel, your distro) and the output of gdb
commands

Dear Benny and others,
So it seems I wasn’t being patient with GDB and it does show me some output. This error of
qemu-img convert even is failing and preventing updating ovirt-node version from 4.3.2 to
4.3.3.1. I get a feeling this is an unrelated error, but I thought I’d be complete:
Excuse any typos, im having to type this manually from a remote session, but the error:
[733272.427922] hid-generic 0003:0624:0249.0001: usb_submit_urb(ctrl) failed: -19
If this bug is preventing even a local yum updatei can’t see how it’s any issue other than
somehow involved with the hardware of the hypervisor, our network and storage
configuration must be irrelevant to this fact at this stage?
Regards,
Callum

gdb has a blank output for this though. This means 4.3.2 is fairly unusable for us, so two
questions, can I downgrade to 4.2, and is there a fix coming in 4.3.3 for this?

Dear All,
Further to this, I can't migrate a disk to different storage using the GUI. Both disks
are configured identically and on the same physical NFS provider.

Dear All,
It would seem this is a bug in 4.3.? - As upgrading the old oVirt HE to 4.3 (from
4.2.latest) now means that the export of VMs to export domain no longer works.
Again qemu-img convert is using some cpu, but no network. Progress is 0.

Dear All,
We've exported some VMs from our old oVirt infrastructure and want to import them into
the new one, but qemu-img appears to be failing. We have mounted an export domain
populated from the old oVirt in the new hosted engine and are using the GUI to import the
VM. Manually running the command sits at 16% CPU, 0% network usage and no progress. It
appears to lock the NFS mount and ls and lsof both hang.
sudo -u vdsm /usr/bin/qemu-img convert -p -t none -T none -f raw <path to source> -O
raw <path to dest>
Conversely a simple cp will work (ruling out file permissions errors):
sudo -u vddm cp <path to source> <path to test>
What might we be doing wrong?

Callum
