Description Maciej Malesa 2013-09-13 15:24:41 UTC

Description of problem:
When I try to clone a VM from snapshot the UI shows blank modal window and it stays blank forever. In engine.log there are messages like those:

2013-09-13 17:12:14,710 ERROR [org.ovirt.engine.core.bll.GetVmConfigurationBySnapshotQuery] (ajp--127.0.0.1-8702-16) Query GetVmConfigurationBySnapshotQuery failed. Exception message is Element type "openstack" must be followed by either attribute specifications, ">" or "/>".

I use GlusterFS as the base for POSIX Storage Domain.

Version-Release number of selected component (if applicable):
oVirt 3.3.0 release 3.el6
glusterfs 3.4.0 release 8.el6

How reproducible:


Steps to Reproduce:
1. Create VM using Posix Storage Domain based on GlusterFS
2. Create snapshot of this VM (with or without 'save memory' checked)
3. Clone VM from the snapshot

Actual results:
UI modal window stays blank forever. Engine.log filled with messages like:
2013-09-13 17:12:29,162 ERROR [org.ovirt.engine.core.bll.GetVmConfigurationBySnapshotQuery] (ajp--127.0.0.1-8702-13) Query GetVmConfigurationBySnapshotQuery failed. Exception message is Element type "openstack" must be followed by either attribute specifications, ">" or "/>".

Expected results:
Showing modal window that allows to enter new name for a VM and successfully create VM from snapshot.

Comment 1 Maciej Malesa 2013-09-14 01:13:48 UTC

I also tried to delete snapshots that may not be used and failed. I stopped the VM and issued snapshot delete. OVirt failed with the message that it failed to do so.
From this point I am unable to create snapshot.

I attached engine.log(In reply to Maciej Malesa from comment #0)

Comment 3 Maciej Malesa 2013-09-14 11:37:11 UTC

Now I created snapshot from a different, running VM (without 'save memory'). It said: "Failed to create live snapshot 'test1' for VM 'report2-sl'. VM restart is recommended". 
After that there was a message in UI that creation of the snapshot was completed with a green mark: "Snapshot 'test1' creation for VM 'report2-sl' has been completed.". The snapshot was not visible right after the creation, but the "Clone" option became available (even though that there were no snapshots visible). I refreshed the administration panel and it became visible after that.

The cloning from this snapshot results the same as before (engine.log.2.txt attached).

Then I stopped the VM and clicked 'Delete' button with the newly created snapshot selected. It was deleted successfully (at least there was no error in the UI and engine.log).

This VM had preallocated disk. When I created the snapshot from the VM that had tiny-provisioned disk and deleting it afterwards resulted in the BROKEN state of the snapshot (this should be included in the first engine.log - 2013-09-14 02:55:07,651).

Comment 5 Nir Soffer 2013-09-25 21:00:37 UTC

Please specify ovirt, vdsm and glusterfs versions and software used on the machine running ovirt engine and host.

Comment 6 Maciej Malesa 2013-09-26 13:58:43 UTC

Hi.
Ovirt-engine:
Version     : 3.3.0
Release     : 4.el6 (I upgraded from 3.el6 and still the same)

vdsm:
Version     : 4.12.1
Release     : 2.el6

Version     : 3.4.0
Release     : 8.el6

Today we had a network outage that resulted in lack of network connection between all parts of ovirt gluster (ovirt-engine, vdsm-nodes and gluster-nodes). Gluster Storage (POSIX) after everything went back to normal, is in 'Unknown' state. I cannot activate it now because of the errors in SPM election (every Host has mounted glusterfs share):

Therefore I am unable to test snapshots.

Comment 7 Maciej Malesa 2013-09-26 14:53:59 UTC

OK. The problems with Storage domain and gluster are now resolved and I can test snapshot creations. 

The error with storage domain was the split-brain situation on one of gluster ids files. Thanks to samppah on #ovirt i was able to fix the problem.

Comment 8 Allon Mureinik 2013-09-29 07:25:45 UTC

Sounds like a malformed OVF in the database.

Are you using OpenStack in any way?

can you please run the following query on the database and attach the result?
SELECT vm_configuration FROM snapshots WHERE description = '<name of your snapshot>'

Comment 9 Maciej Malesa 2013-10-01 10:04:18 UTC

Hi.

No, I am not using openstack in any way.

The result of the SQL query You provided is:

Comment 10 Allon Mureinik 2013-10-01 16:39:47 UTC

OK, here's the problem:

When writing the SpecParams to the OVF the values are not escaped:
<SpecParams><vmPayload><file><openstack/latest/meta_data.json>ewogICJsYXVuY2hfaW5kZXgiIDogIjAiLAogICJhdmFpbGFiaWxpdHlfem9uZSIgOiAibm92YSIs

Notice the string "</openstack/latest/user_data></file><volId>config-2</volId>" which is illegal inside an XML file.

Michal, do you have any insight on this?
Seems unrelated to the storage used here.

Comment 11 Michal Skrivanek 2013-10-01 16:52:18 UTC

yeah, we should check the ovf code...

And snaphots are still buggy. When I click 'clone' for a given snapshot it opens a new modal window and hangs indicating loading some content.

Comment 14 Omer Frenkel 2013-10-27 10:36:51 UTC

This issue has been fixed by the fix for bug 997910
seems this fix missed 3.3.0.1 but it should be in oVirt 3.3.1

but issue will continue if trying to use existing snapshots with broken ovf data
i will send a patch to fix upgrade of existing "bad" snapshots

Comment 15 Michal Skrivanek 2013-11-12 08:16:35 UTC

decreasing prio since the original problem is already fixed

Comment 16 Sandro Bonazzola 2013-11-28 15:33:44 UTC

Re-targeting to 3.3.3 since the bug is not resolved in 3.3.2 beta and is not blocking 3.3.2 release tracker (bug #1027349)

Comment 17 Sandro Bonazzola 2014-01-22 11:29:01 UTC

Re targeting to 3.3.4 as not blocking 3.3.3 release.

Comment 18 Omer Frenkel 2014-02-17 08:12:33 UTC

closing, since the issue can only happen on 3.3.0,
when taking live snapshot for vm that was run with cloud init (or first run for linux vm), this was fixed in 3.3.1.
fixing upgrade to these doesnt seem to be worth the trouble.

a simple work-around for existing 'bad' snapshots is to remove the wrong xml part from the snapshots table.

please re-open if you think we do need to fix it.
