oVirt 3.5 on Ubuntu? [oVirt Dockerized]

by Moran Goldboim

Deploying oVirt engine has never been so easy. Checkout oVirt dockerized projects on docker hub[1] and github[2]. You can find some overview on oVirt-dockerized blog[3] Please let me know if you find it useful. Cheers, Moran.

Hi, after some reboots one of the nodes is still in the Tasks tab in ovirt-gui with message: "Handling non responsive Host babserv.cls" But this is not true my host is running and green in the gui, even more there several VMs running on it. Are there way to fix it?Some how remove this misleading message from the Tasks Tab?

Re: [ovirt-users] about testing scenario

I am not aware of a "best practice" ntp doc for ovirt. There is plenty of information about this over the net, search e.g. for "time sync in virtual machines" or something like that. AFAIK, one thing you should not do, for the time being at least, is assume that if you keep your hosts' clock synced, the VMs' will be too automatically. > I will need my VMs sincronized in time, and also the engine and the native > hosts. > How do you manage that ? > Is there a ntdp runing on some VM isolated from the ntpd running in the > engine ? I think most people just treat VMs just as physical ones and run their favorite ntp client everywhere, pointing both hosts and guests at their organization's ntp server(s). That one (the organization's ntp server) some people tend to put on physical hardware (not a VM), which I guess makes some sense. Best, -- Didi

NFS Storage: domain locked by NFS-provider?

by shimano

Hi all, I tried to configure NFS Storage Domain with load balance by configuring different IPs on Hosts for the same NFS-hostname and running few NFS servers on those machines (NFS exports from MooseFS cluster). Unfortunatelly after correct add and attach Storage Domain, all Hosts are switching to Non-operational because of problems with access to that Storage Domain. Is oVirt making any locks on NFS SD's metafile?

self hosted storage engine disaster recovery procedure

by Ron V.

Hello, I am getting familiar with oVirt and using the self-hosted engine on an iSCSI SAN and so far everything seems quite impressive. I am trying to document a disaster recovery mecanism using a full OS backup as well as a engine backup as described at http://www.ovirt.org/Ovirt-engine-backup I am unclear however how to prepare the existing iSCSI LUN to receive the data restore. I am able to destroy the engine and the VMs continue to run, however I am unclear how I can free the host lock on that LUN, format it and re-install on it. Is there a howto/document I can refer to in order to do this? I am looking for info as to how I can re-install a functional engine from a backup in the case of data-corruption or any other disaster that could happen on the iSCSI LUN set aside for the engine, and a means to re-install on that LUN should the need be, without having to power down the VMs or worse, power everything down and re-install everything from scratch. How can I boot a CentOS install disk and have the previous's engine LUN as a install target, and then boot that installed OS to restore the engine backup data? Thanks in advance, Ron

iSCSI interface to GlusterFS cluster

by Bill Dossett

--_000_B47F00825D68444ABC03733078275360377B1545013BR1MPN1011MG_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi, Not sure if this can be done using ovirt engine or if I have to do this mor= e at the GlusterFS command level. I have set up a Gluster enabled Cluster with a Volume which is working fine= .... I can mount it using the filesystem thype glusterfs. While I am going to test this with Ovirt and VMs eventually. I am currentl= y exploring using the cluster as an iSCSI target and if that is possible to= configure thru ovirt or if I now need to work more at the Gluster command = level and don't get to use the nice UI to configure this. Any pointers to what I should read next about this would be appreiciated.

Hi Itamar, Still not...it's a bug in the Ovirt 3.5.1 https://bugzilla.redhat.com/show_bug.cgi?id=1208416 https://gerrit.ovirt.org/#/c/39484/ Hope this can be resolved in 3.5.2...but it seems they will resolve it in 3.6...
