This is tracked in the following bz:

IIUC it should not do anything to the engine vm or the ha daemons.

Re: [ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

Would like to get this issue settled before I move on… Should I expect to see 
the hosted engine VM showing up in the “VMs” node, or is it a “hidden” VM 
because of it’s special status?

Also, I see that I can change the name of the 1st host if I select it in the 
“Hosts” node, and choose “Edit”… Would it cause any problem if I rename it 
there (how would that effect the engine VM, if at all?)

Also, just noticed that I’m getting the message “The Hosted Engine Storage 
Domain isn’t Active” in the Events pane, but I do not see that domain anywhere 
now in the Storage node in the Datacenter… What must I do to activate this?

So when exactly did you changed the hostname?
And what did you pass to the hosted engine install as answers? perhaps
share the setup log under /var/log/ovirt-hosted-engine-ha

You have to have a data center active, and only after that you would be
able to see your engine VM.  This is a must. First your hosted_storage will
be imported into the setup automatically followed by the engine vm import.

no. We don't mess with that. The hostname is static in the engine.

Re: [ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

I meant “ovirt-node-01” below, not “ovirt-host-01”… so the sentence should have 
read:

‘I would expect that the last entry would be for “ovirt-node-01”, not 
“ovirt-engine-01”…’

Sorry for any confusion...

Re: [ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

Hi Roy,

I did not ever change the engine name… When I deployed it with ‘hosted-engine 
—setup’ I gave it its’ own hostname/IP, assuming it would need one that’s 
different from any of the virtualization hosts. So the virt hosts have names / 
IPs as follows:

ovirt-node-01   xxx.yyy.zzz.91
ovirt-node-02   xxx.yyy.zzz.92
ovirt-node-03   xxx.yyy.zzz.93

…and the engine VM has the hostname / IP as follows:

ovirt-engine-01   xxx.yyy.zzz.95

The engine setup log can be viewed at: http://ur1.ca/od171

I clicked on the “Data Centers” node on the left nav of webadmin, and I see 
that the “Default” DC (the only one I have) has a status of “Uninitialized”… 
Not sure how to initialize it (there’s no menu option for that on the node…)

Thanks,
Will

Think I found the issue… Something caused the glusterd service on ovirt-host-03 
to segfault… Restarted it, and then went ahead and configured a GlusterFS 
storage domain for Data, which worked, and now the DC status is “Up"… Funny

[ovirt-users] Hosted engine vs. hypervisor hosts naming on hyperconverged setup

[Will Dennis]

Hi all,

I have a hyperconverged setup where I have a hosted engine that runs on one of 
three hosts, which are named “ovirt-node-[01,02,03]” —

[root@ovirt-node-01 ~]# hosted-engine --vm-status | grep -e "Hostname" -e 
"Engine"
Hostname   : ovirt-node-01
Engine status  : {"health": "good", "vm": "up", "detail": 
"up"}
Hostname   : ovirt-node-02
Engine status  : {"reason": "vm not running on this host", 
"health": "bad", "vm": "down", "detail": "unknown"}
Hostname   : ovirt-node-03
Engine status  : {"reason": "vm not running on this host", 
"health": "bad", "vm": "down", "detail": "unknown”}

When I deployed the hosted engine, I gave it a separate hostname/IP, as I 
expected it would need it (hostname = “ovirt-engine-01”) 

However, when I look at the hosts in the oVirt web admin screen, I see that the 
first host has the name “ovirt-engine-01” whereas it has the hostname of 
“ovirt-node-01”

I also notice that even though the 1st host is showing the number of VM’s 
running as “1”, when I click on the “VMs” node, there are no VMs showing.

Not sure of what “should be”, but, would expect that the first host would have 
a name equal to its DNS hostname (like the other two do), and that in VMs I 
would see the engine VM. But is that not how a hosted engine setup works?

And if not, if the engine VM migrates over to another host, will that host gain 
the name "“ovirt-engine-01”?

I ask this now because I want to set up a storage domain on these hosts using 
GlusterFS, and I have to select a host to base the connection on. In the “Use 
Host” dropbox, I currently see the values:

ovirt-node-03
ovirt-node-02
ovirt-engine-01

I would expect that the last entry would be for “ovirt-host-01”, not 
“ovirt-engine-01”… 

I don’t want to set up the storage domain until I figure this out, so as to 
prevent potential breakage...

Thanks,
Will
