Hello oVirt folks.
I’m a traitor of the Xen movement and was looking for some good alternatives for XenServer
hypervisors. I was aware of KVM for a long time but I was missing a more professional and
appliance feeling of the product, and oVirt appears to deliver exactly what I’m looking
for.
Don’t get me wrong, I’m not saying that Xen is not good, I’m looking for equal or better
alternatives, but I’m starting to get frustrated with oVirt.
Firstly I’ve tried to install the oVirt Node on a VM in VMware Fusion on my notebook, it
was a no go. For whatever reasons I don’t know vdsmd.service and libvirtd failed to start.
I make sure that I was running with EPT support enabled to achieve nested virtualization,
but as I said: it was a no go.
So I’ve decommissioned a XenServer machine that was in production just to try oVirt. The
hardware is not new, but’s it’s very capable: Dual Xeon E5506 with 48GB of system RAM, but
I can’t get the hosted engine to work, it always insults my hardware: --- Hosted Engine
deployment failed: this system is not reliable, please check the issue,fix and redeploy.
It’s definitely a problem on the storage subsystem, the error is just random, at this
moment I’ve got:
[ ERROR ] Failed to execute stage 'Misc configuration': [-32605] No response for
JSON-RPC StorageDomain.detach request.
But on other tries it came up with something like this:
No response for JSON-RPC Volume.getSize request.
I was thinking that the problem was on the NFSv3 server on our FreeNAS box, so I’ve
changed to an iSCSI backend, but the problem continues. This happens at the very end of
the ovirt-hosted-engine-setup command, which leads me to believe that’s an oVirt issue.
The OVA was already copied and deployed to the storage:

At this point I really don’t know what I should try. And the log file is too verborragic
(hoping this word exists) to look for errors.
Any guidance?
Thanks,
V.
