[ovirt-users] Migrating to a Hosted Engine does not work as expected. Cluster name/id problem?
Hi, I've been trying for sometime to migrate from a bare metal to a hosted engine. Failed about 6-7 times now. Facts: - Ovirt Engine version is 3.4 - 6 hosts on a cluster named MYCLUSTER, Westmere CPU Type - About 50 VM's on MYCLUSTER cluster. - NFS Storage domain - Cluster Default is empty: no hosts, no VM's, only the Blank template (I didn't know I could just rename it when I deployed it) The first times I tried to deploy it, the hosted-engine VM and host ended up in the Default cluster. So I renamed the Default cluster Default1 and then MYCLUSTER to Default using the web gu on the bare metal manager, prior to generating the backup I later restored on the hosted one. This time, the host was correctly added to Default together with the other hosts and VM's, but the hosted engine VM was added to the Default1 cluster. I'm then left with: - a HostedEngine VM which looks down on the engine, even though I'm looking at the web-gui running on it. - a host that shows 1 vm running on it, but have no Vm's listed - trying to do anything with the HostedEngine Vm on the web-gui issues VM is not managed by this engine error - trying to move it to the Default cluster shows the same error I then decided to take a look at the engine DB and tried to alter tables vm_static and vm_dynamic to reflect the correct cluster (vds_group_id) and host configuration, but that did not work (I didn't have a lot of hope anyway). I'm now back to a working bare metal engine. Is there a way to go around this problem? -- Gustavo Campos ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] status of ovirt 3.5.1 with centos 7.1
Hi. I wanted to check on the status of ovirt 3.5.1 with CentOS 7.1. I'm pretty sure the current 3.5.1 engine has problems with CentOS 7.1 (?), but not sure about vdsm? I know that 3.5.2 will resolve issues with engine... (I'm asking because I've kickstarted CentOS 7.1 as a host, and am having a few problems (eg. unable to talk to power management) and want to avoid debugging if it's already known to be broken... :) Thanks!

No, my engine is on CentOS 6 (I installed it with oVirt 3.5.0 when CentOS 7 engine support wasn't ready). Yep .. It's for an idrac7...

It was working perfectly with ovirt-node, but now that I've switched from node to using my own CentOS 7.1 install, the problem was introdued. Hmm, I also have idrac7, but I only need lanplus. It worked okay until I upgraded the hosts to CentOS 7.1 this week. I suspect something changed in the resource agents and either vdsm was sending something slightly wrong that no longer works, or there's a new bug in the resource agents (since vdsm didn't change). -- Chris Adams c...@cmadams.net ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] Hosted-Engine Setup: Failed to setup networks
Hi All,
fixed it, vdsm doesn't like the PREFIX entry in the ifcfg file. After changing
that to NETMASK it worked.

Hi Everyone,
I tried to install oVirt 3.5 - hosted engine and it fails with some VDSM error
while creating the ovirtmgmt bridge. The Host is running CentOS 7 and the
interface I want to use is em1 and it's the parent interface from a vlan.

Is there anything I can do like creating the bridge manually or use older
version of the packages that don't have that issue ?
Thank you,

Re: [ovirt-users] metadata not found
We see this, too. It appeared (if i didnt miss something) either with
el7 + ovirt 3.5 or with ovirt 3.5 no matter if its el6 or 7. Doesnt seem
to have any further impact so far.
