Internal Engine Error while adding a new (distribute glusterfs) Storage Domain
by Konstantinos Christidis 14 Jul '15

14 Jul '15

Hello, I created (through oVirt web) a GlusterFS distributed volume with four bricks. When I try to add a New Domain - GlusterFS Data I am getting Error while executing action Add Storage Connection: Internal Engine Error and Error validating master storage domain: ('MD read error',) Full logs engine.log - https://paste.kde.org/pefcwndgc/zamd2o/raw vdsm.log - https://paste.kde.org/pxf91znwq/6mhrg3/raw Gluster info/options - https://paste.kde.org/pjfauvisg/grfrvj/raw (oVirt3.6/Centos7) ps: My installation seems to work only with replica-3 oVirt Optimized volumes. Every other combination fails with the error above. Any help would be appreciated. Thanks, K.

ovirt-Node + hosted engine question
by Alan Murrell 14 Jul '15

14 Jul '15

Hi All. As I was perusing my e-mails from this list earlier today one that caught my attention was one that had to do with ovirt-node and hosted engine. It appeared as though it is possible to install hosted engine on a ovirt-node "host", and indeed, when I installed ovirt-node into a VirtualBox VM to poke around, there is a "hosted engine" option in the menu where you can enter a URL for an ISO/pxe source for OS installtion. I just want to clarify the following questions: 1.) Is it possible to install ovirt-node, and then install a hosted engine? 2.) If the answer to 1.) is "Yes", does it require some sort of NFS-enabled storage, or can you confgiure local storage on ovirt-node and install the engine to there? 3.) Is it possible to create NFS-enabled storage on ovirt-node? 4.) Can you install the hosted engine onto external NFS storage, then move/migrate it to local storage on ovirt-node? I am thinking of a "lab" situation where there is only one server, but gobs of RAM and storage. Running ovirt-node as the "host" would require fewer space resources (not that I would necessarily be hurting for space, but any extra I could squeeze out would not be unwelcome). Thanks! :-) -Alan

This VM is not managed by the engine
by Mark Steele 13 Jul '15

13 Jul '15

I have a VM that was not started and is now showing as running. When I attempt to suspend or stop it in the ovirt-shell, I get the message: status: 400 reason: bad request detail: Cannot hibernate VM. This VM is not managed by the engine. Not sure how the VM was initially created on the ovirt manager. This VM is not needed - how can I 'shutdown' and remove this VM?

Live VM Backups
by Chris Jones - BookIt.com Systems Administrator 10 Jul '15

10 Jul '15

From what I can tell, you can only backup a VM to an export domain if the VM is shut down. Is a live VM backup not possible through oVirt? If not, why not? Most other virtualization tools can handle this. If it is possible, how do I do it through the backup API? api.vms.myvm.export requires it to be shutdown so what would the alternative be? Thanks. -- This email was Virus checked by UTM 9. For issues please contact the Windows Systems Admin.

Unable to shutdown, poweroff or delete a VM

We are running oVirt Version 3.5.0.1-1.el6. I have a VM on one of my hosts that appears to be stuck. The VM shows running, however I am unable to successfully shutdown, powerdown, or otherwise change the status of the VM. It is not pinging. The guest OS is Ubuntu 14.04 and the ovirt agent is installed. I have attempted to stop the vm from the ovirt-shell as well and get the following errors for each command: [oVirt shell (*connected*)]# action vm connect-turbo-stage-03 stop *============================================================== ERROR ===========================================================* * status: 400* * reason: Bad Request* * detail: Unexpected exception* * ================================================================================================================================* [oVirt shell (*connected*)]# remove vm connect-turbo-stage-03 *============================================================== ERROR ===========================================================* * status: 409* * reason: Conflict* * detail: Cannot remove VM.

how to configure virtio-scsi as a default disk interface in userportal/webadmin?

Hi, I was wondering about $SUBJ. Is it governed by interfaces order in osinfo properties? Or somewhere else? I hope that virtio-blk isn't hardcoded... Best regards, David Jaša

Re: [ovirt-users] oVirt 3.5.3 Host Network Interfaces
by Soeren Malchow 07 Jul '15

07 Jul '15

Dear Michael We actually created the ovirtmgmt and the bond manually upfront and then in the ³Setup Hosts Network² we basically did this again (including setting the IP address), regarding the bonding in the gluster network we did not have a problem, you just drag one interface onto the other and then select the bonding mode, where you can also go for bonding mode TLB or ALB if you choose ³custom² or just LACP if you have switches that support this. Step by Step: - set the engine to maintenance and shut it down - configure the bond on the 2 nics for the ovirtmgmt bridge ( em1+em2 -> bond0 -> ovirtmgmt ) - configure the IP on the bridge - reboot the server and see whethter it comes up correctly - remove maintenance and let engine start - Set up the ovirtmgmt in hosts networks but do not forget to set IP and Gateway as well. Though it should work without this hassle (if the bonding mode on the switch and server is compatible) but this way it is easy to get server and switch in the same mode and working without having to do anything in ovirt first. Hope that helps Regards Soeren On 02/07/15 00:31, "users-bounces(a)ovirt.org on behalf of Prof. Dr. Michael Schefczyk" <users-bounces(a)ovirt.org on behalf of michael(a)schefczyk.net> wrote: >Dear All, > >Having set up a Centos 7 server with Gluster, oVirt 3.5.3 and hosted >engine according to >https://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/, >I was hoping that the NIC management and particularly NIC bond/bridge >capabilities would have improved a bit.

Metadata error on hosted engine (fresh install)
by Matteo 06 Jul '15

06 Jul '15

Hi all, I've activated oVirt 3.5 with the hosted engine setup using CentOS 7 as host and CentOS 6 as engine OS. The storage for the hosted engine is iSCSI. The setup went smooth, I've some vm running on top of it without many issues. Right now I've some issue with hosted engine metadata: if I try to add an additional node, at the end of the deploy sequence it fails with error: Failed to execute stage 'Setup validation': Metadata version 9 from host 5 too new for this agent (highest compatible version: 1) On the first host, "hosted-engine --check-liveliness" confirms that the engine is up (Hosted Engine is up!) , but "hosted-engine --vm-status" fails with a python exception: Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 116, in <module> if not status_checker.print_status(): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 59, in print_status all_host_stats = ha_cli.get_all_host_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 155, in get_all_host_stats return self.get_all_stats(self.StatModes.HOST) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 102, in get_all_stats stats = self._parse_stats(stats, mode) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 141, in _parse_stats md = metadata.parse_metadata_to_dict(host_id, data) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/metadata.py", line 147, in parse_metadata_to_dict constants.METADATA_FEATURE_VERSION)) ovirt_hosted_engine_ha.lib.exceptions.FatalMetadataError: Metadata version 9 from host 5 too new for this agent (highest compatible version: 1) looking into metadata file, which is really a block device (via some symlinks), I see a lot of binary data after plain ascii text. Dumping this device results into a 134MB file. ( if someome is curious, the dump is here: https://cloud.brancaleoni.com/index.php/s/4Lx3M5PXkqhO80N ) Reading other posts where the setup was over nfs was suggested to truncate the file, but this is a device file and I'm not sure what to do. Any hint on where I can look at ? Thanks, Matteo

GlusterFS Hyperconvergence
by Tiemen Ruiten 06 Jul '15

06 Jul '15

Hello, I'm in the planning stage of setting up a new oVirt cluster, where I would prefer to use the local disks of the hypervisors for a GlusterFS storage domain. What is the current recommendation (for version 3.5.x)? I found this presentation which seems to suggest that it's possbile with some caveats: http://www.ovirt.org/images/6/6c/2015-ovirt-glusterfs-hyperconvergence.pdf And a few open bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1177791 https://bugzilla.redhat.com/show_bug.cgi?id=1177775 https://bugzilla.redhat.com/show_bug.cgi?id=1177773 What I can't find is current information on if this setup is already possible with 3.5.x or it's better to wait for 3.6. Could someone enlighten me? -- Tiemen Ruiten Systems Engineer R&D Media
