[Users] ovirt engine in high availability
by Gianluca Cecchi 12 Mar '14

12 Mar '14

Hello, I have made a base testing environment putting engine in HA. I think it could complement self hosted engine. As this could be of interest for enterprise based installations, I used CentOS 6.5 as OS environment for engine. Even if in upcoming RH EL 7 it seems corosync will substitute cman, in this 6.5 test I have used cman/pacemaker with pcs commands. The engine servers are two vSphere VMs, so I tested the configuration both without stonith and with vSphere CLi sdk and fence_vmware fenging agent. Also, as this kind of environment could be suitable for DR too, I set up the filesystem resource with drbd in active/passive. There are many possible configurations; to stick with similar environment as the standalone engine, I configured the whole stack of resources in one group, also with the nfs share for the default ISO-DOMAIN. Actually in this kind of environment it would be preferable to have a dedicated nfs resource on another ip so that it doesn't influence the ovirt-engine resource that is more critical. In the same way one could choose to put the PostgreSQL resource as a separate one, optimizing and balancing nodes' utilization. At the moment I successfully tested on ovirt-engine-3.3.3-2.el6.noarch and I have not yet configured any hypervisor hosts. I will do next days. I plan to test also upgrades to 3.3.4 and 3.4.0, to see if maintenance activity would reveal too complex and be a show stopper. In the mean time what I tested to be transparent with a client session connected to webadmin portal is: - relocation of resources - power off of the passive node - power off of the master node With transparent I mean that in the same browser window the user gets the login page (the same as when it goes timeout) and after login it gets the same situation as before. Obviously the PostgreSQL rdbms has stopped (or crashed in third case) and so problems could arise as if you stopped your db or powered off your server in single server environment. If there is interest I can post my configuration steps into a wiki page on oVirt web site (after learning the formatting syntax... ;-).. the page name could be something like "clustered_engine". In the mean time if you have any scenario I can test to verify consistency you are welcome. Gianluca

[Users] Foreman and oVirt 3.4 fails
by Andrew Lau 11 Mar '14

11 Mar '14

Hi, Is anyone using Foreman with oVirt 3.4? Post upgrade, I appear to be having some issues with Foreman reporting " undefined method `text' for nil:NilClass" I'm not sure if this ends up being a Foreman issue or oVirt, or it could just be my install gone bad.. however last time it was the oVirt API had been updated which caused issues with Foreman so I thought I'd post here first. Thanks, Andrew

[Users] Confused about Gluster usage
by Martijn Grendelman 11 Mar '14

11 Mar '14

Hi, I have been running oVirt 3.3.3 with a single node in a NFS type data center. Now, I would like to set up a second node. Both nodes have plenty of storage, but they're only connected to each other over 1 Gbit. I'm running nodes on CentOS 6.5. What I would like to accomplish is: * use a Gluster-backed DATA domain on my existing NFS datacenter * load balancing by even spread of VMs over the two nodes * leveraging the speed of local storage, so running a VM over NFS to the other node is undesireable So I was thinking I want the storage to be replicated, so that I can take a node down for maintenance without having to migrate all the storage to another node. I was thinking: GlusterFS. But I am confused on how to set it up. I understand I cannot use the libgfapi native integration due to dependency problems on CentOS. I have set up a replicated Gluster volume manually. How can I use my two nodes with this Gluster volume? What are the necessary steps? I did try a couple of things; most notably I was able to create a 2nd data center with POSIX storage, and mount the Gluster volume there, but that doesn't work for the first node. Alternatively, it would also be fine to migrate all existing VMs to the POSIX datacenter and then move the existing node from the old NFS data center to the new POSIX data center. Is that possible without exporting/importing all the VMs? Cheers, Martijn.

[Users] ovf image for hosted engine
by Jason Brooks 11 Mar '14

11 Mar '14

Hey all, The hosted engine may be installed from pxe, cdrom or disk. The disk format must be an OVF image, right? Any suggestions on how to create an ovf image? Poking around, I see mentions of tools to convert from ovf, but not to ovf, at least not within the KVM/libvirt world. I know that this format is used within oVirt, but I don't understand how to go from the *.ovf file in the export domain + the disk image file or files to a single disk image. Do these have to be zipped together? Is there some utility for that, or guidance on how it comes together? My cdrom and pxe hosted engine installs have been spotty -- some crashes, some unresponsiveness from pxe and from the cd install -- so I'd like to know how to take the disk route... Thanks, Jason
