FQDN or fully qualified domain name means that you have to reserve in your DNS a name
corresponding to IP received by HE VM from DHCP.
IP address should be reserved for the VM at DHCP.
I advise not to use manual IP to FQDN at your host, as this will lead to many confusions,
especially when you'll have more than a single host machine, but you always can
configure at your /etc/hosts file the FQDN corresponding to IP address given to HE VM.
Thanks in advance.
Best regards,
Nikolai

Hi
Now I am trying to confirm KVM's HA with ovirt, and doing the walk through as the
following guide.
http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/
During the VM setting, FQDN is asked, what FQDN means about? Does it mean the hostname of
VM host? In my case, it is compute2-2.
The following is my hosts file, my VM host and storage is 10.0.0.92.
And I am trying to assign 10.0.0.95 to the hosted VM.
---
[root@compute2-2 ~]# cat /etc/hosts
10.0.0.93 compute2-2 nfs2-2
10.0.0.95 ovrit-test
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
----
Also how I can remove the VM I installed, as for when I try to do hosted-engine --deploy,
it shows
---
[root@compute2-2 ~]# hosted-engine --deploy [ INFO ] Stage: Initializing

Hey All,
I think I have found a bug in oVirt 3.4.4. We just bought a new server that
supports the Conroe CPU model, and I am trying to install Server 2012 R2
without luck. I keep getting error code 0x000000C4. The problem is while
Windows is still to load into its pre-installation environment it cashes
and then immediately resets. This is a continuous loop. I have found a way
to install Server 2012 R2. Move the cluster away from the Conroe Family (in
my case Penryn). Thanks for all you do.

Is there a way to force oVirt to place a host into maintenance mode
automatically when a problem occurs? The problem we have is separate
networks for everything:
2 public nics which are bonded active/backup for internet access
4 bonded gigabit nics for our Gluster network
1 IPMI
The ipmi is on a completely different network, not attached to anything else
other than a VPN.
///
Our cluster servers shared Gluster & hypervisor on the same hosts, which
works great however, all are 1U servers so we don't have room for another
NIC to dedicate to just an ipmi network connection in addition to the ipmi
card itself. Even if the PSU on a host fails, then the ipmi power management
is useless anyhow and the VM's on that host will not be moved.
I've tested putting a host into maintenance mode with running VM's and it
will auto-migrate the VM's without issue. Is there a way to make oVirt just
force a host into maintenance mode if there's some sort of problem or some
other fencing mechanism that will allow the VM's to be migrated to another
host?

Of course if you need to troubshoot the system, and the vm is not
running, there is no problem to access the lv directly.
Even then, you should *not* activate all lvs in a vg using
vgchange -a y
But activate only the lv you want to access using
lvchange -a y

This not the output of lvs, these are the symlinks to the active lvs.
Can you share the lvs output before and after the vm is stopped?
No, since the vm does not start!

I'm not sure what you mean. Can you share the output of lvdisplay before
and after the operation?
Already is not present, I have removed this problem disk

Did you update lvm cache using "pvscan --cache"?
No. I should after each operation with disks, do in the console "pvscan -
cache"?

What do you mean by that?
This is first problem! Second problem - don't start the vm.

Is the volume preallocated or thin provisioned?
All my disks - prelocated.
Preallocated volumes are extended when you modify the volume size in
engine ui (as you described). Thin provisioned volumes are extended
only when the available space is bellow a threshold, so the lv
size will not change after you modify the volume size.

Do you mean that now everything works?
The VM it has been removed, since for a week I could not start it!
Now all works on others VM. But there were 2 problems! My problem to
understand, that I have made not so or it is a problem oVirt.
I wish to use oVirt, but is not assured of it because of these problems!

Lost you here.
It agree, a head around ))
