Re: [ovirt-users] hosted-engine --deploy Failed

[Joe DiTommasso]

I was having the same issue. I've blown away my logs, but VDSM was failing
to start up after attempting to configure vswitch filtering. Have switched
to oVirt Node, which seems to be working.

Re: [ovirt-users] Add nodes to single-node hyperconverged cluster

[Joe DiTommasso]

Thanks! I realized yesterday that I've got a few hosts I was in the process
of decommissioning that I can temporarily use for this. So my new plan is
to build a 3-node cluster with junk hosts and cycle in the good ones.

[ovirt-users] Add nodes to single-node hyperconverged cluster

[Joe DiTommasso]

Hi, I'm currently running an out-of-date (3.6) 3-node oVirt cluster, using
NFS storage. I'd like to upgrade to the latest release and move to a
hyperconverged setup, but I've only got the three hosts to play with. I'm
currently thinking of pulling one node from my current cluster, rebuilding
it to start a new cluster, and then migrating VMs/physical hosts over to
the new cluster. Is that something that would seem feasible? I've read the
documentation on setting up a hyperconverged cluster, but didn't see
anything about adding new hosts after cluster deployment.Thanks!

Re: [ovirt-users] Dumb question: exclamation mark next to VM?

[Joe DiTommasso]

If you mouse over the exclamation mark, you should get a tooltip that tells
you what it's complaining about. I've got it on pretty much all my VMs,
it's an issue with the timezone for me.
