[Users] oVirt API Code 500 with Foreman
by Andrew Lau 06 Sep '13

06 Sep '13

Hi, Foreman guys say this is probably an oVirt side issue.. I was successfully able to hook up my foreman server to the oVirt datacenter using the compute resources section. It detected the available datacenters and logged in fine. Logs showed code 200, I can view the VMs available, power them on and shut them down from the foreman UI. But when I go to hosts->New Host and select oVirt I get the error: Error loading virtual machine information: Internal Server Error Logs are showing: Operation FAILED: statementcallback; bad sql grammar select * from (select * from vds groups view where ( vds group id in (select vds groups storage domain.vds group id from vds groups storage domain left outer join storage pool with storage domain on vds groups storage domain.storage pool id=storage pool with storage domain.id where ( storage pool with storage domain.name like '%dc_01%' or storage pool with storage domain.description like '%dc_01%' or storage pool with storage domain.comment like '%dc_01%' ) )) order by name asc ) as t1 offset (1 -1) limit 100; nested exception is org.postgresql.util.psqlexception: error: column storage pool with storage domain.comment does not exist position: 421 Rendered common/500.html.erb (5.2ms) Completed 500 Internal Server Error in 150ms (Views: 6.0ms | ActiveRecord: 0.3ms) CentOS 6.4 - Foreman 1.2 CentOS 6.4 - oVirt 3.3 Nightly Any suggestions?

[Users] Host stuck in unresponsive state
by Frank Wall 04 Sep '13

04 Sep '13

Hi, my all-in-one host is stuck in unresponsive state, no matter what I try. Found this error in my engine.log: 2013-08-31 23:53:59,325 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesVDSCommand] (DefaultQuartzScheduler_Worker-54) Command GetCapabilitiesVDS execution failed. Exception: VDSNetworkException: java.net.ConnectException: Connection refused This message starts to appear when I try to activate the host (from maintenance state). Any idea how to activate the host? Running oVirt 3.3 RC2 on Fedora 19, all-in-one Setup. Thanks - Frank

[Users] EL6 and gluster domain [was Re: oVirt Weekly Meeting Minutes -- 2013-08-28]

For sure it would be impossible to have the new feature "Gluster Storage Domain" in both plain el6 servers configured as ovirt nodes and in ovirt-node iso for EL6. I'm now following this blocker for 3.3 that is strictly connected with this problem https://bugzilla.redhat.com/show_bug.cgi?id=988299 Latest post I read is from yesterday: " Hi. I was wondering if it is possible to include correct version of qemu into ovirt 3.3 repository as it is required for one of ovirt's main new features - Gluster Storage Domain. Is there any release plan for RHEL 6.5? It seems that it will be a long time for having this feature in CentOS (supported by ovirt as I understand).

[Users] How to add internal networks
by Frank Wall 01 Sep '13

01 Sep '13

Hi, I'm using oVirt 3.2 on a single hosts with only one NIC. Currently there is only the ovirtmgmt network configured. But I need to add more networks, especially some internal networks like 192.168.x.y/24 need to be usable for VMs. From the oVirt Admin Portal this does not seem to be possible. It seems I cannot reuse the ovirtmgmt interface for any other network. Is this true? How am I supposed to add several networks in oVirt if I have just one NIC? Thanks - Frank

[Users] Vlan tagging and VM Interfaces
by Andrew Lau 31 Aug '13

31 Aug '13

Hi, I've got a scenario: Router->Node (vlan tag 100, vlan tag 101)->VM Does the node take care of the tagging or will the VM's interface also need to be tagged. Right now the VM's interface is not in a VLAN and it can't connect to the router. Thanks, Andrew

[Users] Ovirt / Gluster topology + DR site
by Steve Dainard 31 Aug '13

31 Aug '13

Hello all, I'm looking for some opinions on our current topology and how a disaster recovery plan would shake out in the real world on an ovirt/gluster clustered system. Please ignore the RH references in the attached diagram, we're still on the fence if we're going with support or not. [image: Inline image 1] The Plan At HQ site: Two Gluster nodes running as replica's. ~4 Virt notes 1 Manager node (likely running on as separate kvm HA VM) Offsite: 1 Gluster node acting as a geo-replication target 1 Virt node 1 Manager in standby (waiting to recover db backup) *Even better would be using both nodes at this site as one striped gluster volume, standby Manager, and Virt nodes to eliminate the standby Manager box, decrease costs and increase virt resources, but I'm not sure this is doable quite yet.* During regular operations we're replicating our gluster storage offsite with geo-replication. In the event of a disaster (for simplicity we'll say the server room becomes unusable) I would want to recover the Manager at the offsite location from a backup, add the geo-replicated gluster storage domain as the normal domain, then start spinning up the business critical VM's. With a router in-place and some external DNS changes we should be able to keep our VPN accessible and all our internal resources available to mobile/home workers, or in this simple case even from our normal office location (already have the site-to-site VPN active). I'm planning on using a vpls solution to extend the VM subnet and storage/virt subnet across both sites so we don't need to worry about dns/IP changes in the middle of recovery. I think the biggest question so far is can we smoothly replace the normal storage domain on ovirt with the geo-replicated storage domain in the DR situation off-site? I've tried to layout most of the high level stuff here so if anyone sees any flaws or potential gotcha's feel free to chime in. I can provide more detail if necessary. Thanks! *Steve *

[Users] oVirt 3.3 fails to find spice-html5
by James A. Peltier 31 Aug '13

i just installed oVirt 3.3 Beta RPMs on a fresh installation of CentOS 6 on my laptop with all patches applied yum -y localinstall http://resources.ovirt.org/releases/3.3/rpm/EL/6/noarch/ovirt-release-el6-8… yum -y localinstall http://www.muug.mb.ca/pub/epel/6/i386/epel-release-6-8.noarch.rpm After editing the /etc/yum.repos.d/el6-ovirt.repo to enable beta and then trying to install oVirt engine it complains about spice-html5 being unavailable. Is this a bug, or is it temporary. -- James A.
