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 for the explanation. Now I understand what FQDN is for Ovirt. Is there any problem
if I do not use the naming convention like aaa.bbb.ccc, but only aaa?
Also I am some confused for the above explanation. Here it said the IP for VM is better
to be got from DHCP rather than manual IP. If so, do this mean I need to change all
/etc/hosts file of all virt nodes to update the IP for the FQDN for engine VM?
What is the confusions if I use manual IP rather than DHCP for engine VM?
Thanks,
Cong

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
---

FQDN convention should be following your organizational domain conventions, as long as
FQDNS reachable via DNS, should work just fine.
Normally from the beginning you don't have to edit manually /etc/hosts at all, once
your HE-VM getting the same IP from reserved range of DHCP IP addresses and DNS has its
FQDN in its records, since your hosts during hosted-engine-deployment will be given
already known FQDN of the HE-VM instead of its IP, then hosts will get to HE-VM via DNS.
Using reserved IP address range advised, as during some time, if you're using IP
addresses from dynamic pool, you'll eventually will loose connectivity to your HE-VM,
as it's IP will be updated after lease time expires or renewed.
For repeated HE installations with same FQDN for the engine desired, to get always the
same IP address for HE-VM, each time you're deploying it, you will have to write down
it's MAC address, so when asked during deployment to provide MAC address for HE-VM,
you'll just write manually the same MAC address (that very MAC address, that is
already matched in reserved DHCP IP<->MAC pair), this will ensure that your HE-VM
will receive then the same IP address from DHCP and will resolve to FQDN in DNS database
records.
Thanks in advance.

Nikolai

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.

No, since the vm does not start!

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

I wish to use oVirt, but is not assured of it because of these problems!
