Ideally you'd not, you'd use vdsClient.
You can use --readonly if you're happy with read only
We really want to make sure that only vdsm is talking to libvirt otherwise we can get
ourselves into trouble.
If you *really* need to connect with libvirt have a look in this directory on the node
/etc/pki/vdsm/keys/

I need to start ovirt-engine, so I need more then -r.

Understand.

Thanks, I found that same password via google, but I can't find the
username. I have tried a bunch I thought it might by, but get
authentication failed with everything I have tried.

So ovirt-engine is a VM on the node?

iirc it's vdsm@rhevh

Yes, I have a cluster of 20 nodes and don't want to have a static server
for ovirt-engine.

Thanks, that worked with: "virsh -c qemu:///system list", I also found
that on a node I could use "virsh -c qemu+tcp:///system list" and it
worked without a username/password.

Yes, I have a cluster of 20 nodes and don't want to have a static
server
for ovirt-engine.
So the engine is a VM in that same cluster, along with the VMs it manages?
What do you use for storage?

Yes, the only thing I have not been able to figure out is how to let the
ovirt-engine know that ovirt-engine is running. :) I thought that it would
see via libvirt, but it does not. I also tried setting it in the db, but
it keeps getting cleared. Any idea on how to let ovirt-engine know that a
host has been started manually?

Seriously, not a good idea. The Engine is supposed to be looking at the setup, and not be
in the setup, where it may be affected by the problems that might occur to the setup.
I'm pretty sure there's lots of though being devoted to removing this limitation,
but when we say it's a bad idea, it really is, it's not like we simply want you to
run an extra machine

That's easier than block storage, but still, what happens if the host where the engine
was running failed - who would update VM statuses and restart the HA VMs?

Doron - this reminds me of the all-in-one discussion. what was the
resolution on flagging the node as a node running an engine VM (even
without engine knowing about its own VM)

Hmm, find it hard to believe that people are not going to want to run
management on the cluster.
That's easier than block storage, but still, what happens if the
host where the engine was running failed - who would update VM statuses and restart the HA
VMs?
Don't I also run into similar problems if my dedicated host where the
engine was running fails?
