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

Also how I can remove the VM I installed, as for when I try to do hosted-engine 
--deploy, it shows

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 0x00C4. 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

Re: [ovirt-users] FQDN for vm creating with hosted-engine

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.

Do you refer to the following:

Please provide the FQDN for the engine you would like to use.
This needs to match the FQDN that you will use for the engine 
installation within the VM.
Note: This will be the FQDN of the VM you are now going to 
create,
it should not point to the base host or to any other existing 
machine.
Engine FQDN: 

?

We recently changed this text to be so, due to [3]. If you still do
not find it easy to understand, please suggest better wording. Thanks!

The Engine FQDN is the name that is used by others to refer to the
machine on which the engine runs. In this context it's the name of the
VM.

This does not have to be the hostname of that machine - the output of
the command 'hostname' there. E.g. you might want to have a hostname
'purple.example.com' but connect to it as 'my-engine.example.com'.
You'd probably add to the dns an A and a PTR record for 'purple', and
a CNAME record for 'my-engine'. You should then input at this prompt,
as well as the one during engine-setup inside this vm,
'my-engine.example.com'. See [1] [2] as examples for naming conventions.

[1] https://tools.ietf.org/html/rfc1178 - an rfc from 1990, still mostly
relevant today

[2] http://mnx.io/blog/a-proper-server-naming-scheme/ - some random
document found by searching for 'hostname conventions'

[3] https://bugzilla.redhat.com/show_bug.cgi?id=1069945 :
[TEXT] Add a note explaining better how FQDN will be used

 
 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

Seems like you intend to use ovirt-test for the engine, so enter that.

If you set it up with a previous 'hosted-engine --deploy', you can kill it
with 'hosted-engine --vm-poweroff'. If you created it yourself, best use the
same tool - e.g. if with virsh, use that to kill it. You can always use ps
to find the qemu process of it and kill it with 'kill'.
