name of virtual machine and hostname
by nicola gentile
Good morning,
I would like to ask you an information.
After I have installed ovirt, I have created a pool of vm with name
like centos-?? (from 1 to 20)
and then ovirt generated 20 vm with name centos-1, centos-2, centos-3 etc. etc.
The problem is when the vm starts the hostname is not the same of the
vm name in ovirt but is the same name of the template.
Is it possible to make sure that the name of vm and the hostname is identical?
Best regard
Nicola Gentile

ovirt 3.5 rc2 unable to mount cd on running VM
by Gianluca Cecchi
Hello,
installed a CentOS 6.5 x86_64 vm from iso (create VM and then run once
connecting CD iso).
System reboot several times and power on from web admin gui and all seems
ok.
At a certain point I upload guest-tools iso to my engine for future windows
VMs.
Taken ovirt-guest-tools-3.5_5.iso and try to mount it
In engine the downloaded file seems ok and I can loop mount it for test.
[root@ovirtmgr ~]# mount -o loop ovirt-guest-tools-3.5_5.iso /media

It seems to be a general problem. Tried also to mount the iso of CentOS 6.5
that I used to install the VM itself but I get the same error.
Donna if it is somehow related also with what I previously wrote about cd
and install in 3.5 rc2; see

Am I right that this still involves a full operational e.g. esxi host
to import vmware vms?
There is a huge user demand on a simpler process for just converting and
importing an vmware disk image. This feature will not solve this
use case, will it?

Sizing the master storage domain
by Nicolas Ecarnot
Hi,
I know Itamar explained that the notion of master storage domain will
disappear in some releases.
But now, with a 3.4 I'm installing, I was wondering :
- on my other oVirt setups, I started with one big (iSCSI) LUN, which is
the master, and stored as many VMs I could
- when space came to miss, I added another LUN, the another...
- when I have to do some maintenance (grow, disable, other...) on a LUN,
I can move my VM disks amongst the normal storage domains. When Empty, I
can switch them off, add others, and so on
The only one I can not play with is the master one.
I came to think that I had no benefice storing anything on the master
storage domain, and use only the normal storage domains.
And then, I came to think I had no reason to dedicate a huge LUN for the
master.
Ok, but according to you, what is the minimum reasonable size for a
master storage domain?

GlusterFS Distributed Replicate HA with KeepAlived
by Punit Dambiwal
Hi,
I have 4 node GlusterFS Distributed Replicate volume...the same 4 host node
i am using for compute purpose....now i want to make it HA....so if any
host goes down .....VM will not pause and it will migrate to another
available node...
1. Can any one have any document or reference to do this with keepalived...
2. I have one more node as spare...so if any host goes down and can not
come up again because of any HW failure...i can add it...but i didn't find
any way to add these bricks to volume...??
Thanks,

[Users] connecting to oVirt/RHEV VMs through proxy and the oVirt API
by i iordanov
Hello,
My apologies for cross-posting, but this discussion concerns both mailing
lists, I think.
In Opaque, I recently started setting the proxy property of SpiceSession
from a console file, as is done in remote-viewer, in order to support
installations where the nodes are not "visible" from the point of view of
the client.
However, then I remembered that I have not seen the proxy property being
available through the oVirt/RHEV API. I looked at the latest remote-viewer
code, and I looked through the oVirt/RHEV API documentation, and indeed, I
see no way to get proxy information other than through the console.vv file.
If I am correct, then this means that both Opaque and remote-viewer cannot
connect to VMs behind a proxy unless a console.vv file is used, which also
means that since console.vv files are unobtainable through the User Portal
on mobile devices, mobile devices effectively cannot at all connect to such
VMs if the user is not an Administrator.
Would it be possible to expose the proxy parameter through the API? I
couldn't find a bug opened about this, but it doesn't mean it isn't there
:).
Thanks!

delete snapshots or create a template make a huge impact on VMs on SPM-node
by Ricky Schneberger
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
When we do some tasks in ovirt as delete an snapshot or clone a machine
or just want to make a machine template the impact on VMs residing on
the SPM node is huge. Is there a way to prevent this? This is just
normal tasks and we do this all the time.

[Users] How to See Ovirt Console From a Remote Windows Host
by Jon Forrest
I know that this is simple for some of you, but I also
know from Googling around that lots of people have had
trouble seeing their ovirt console from a remote Windows
host. Below I describe what finally worked for me. I hope
this helps somebody avoid wasting as much time as I did
today.
I'm a fairly experienced VMWare user who's learning ovirt.
I just installed an all-in-one ovirt server and copied a
CentOS 6.5 iso into it. I then tried to boot a new VM
but soon learned that console access is different in ovirt
than on VMWare.
I then spent over an hour trying the various documented
ways to view a remote console using Spice on my Windows 7
desktop. I even tried using a Linux VM to see if the Firefox
plugin for Spice would work. Nothing.
What finally worked was installing the virt-viewer Windows
client (http://virt-manager.org/download/). Then, I opened
the ovirt Administration Portal in Firefox running on my
Windows 7 desktop. I created a new VM and configured it
the way I wanted. Then, from the "Virtual Machines" tab, I started
the new VM. Pretty soon the little console icon turned green so
I clicked on it. I got the prompt from Firefox asking me what
app I wanted to associate with the ".vv" URL that opened when
I clicked on the console icon. I browsed around and selected
\Program Files\VirtViewer\bin\remote-viewer.exe
which is from the virt-viewer client package I installed above.
I told Firefox to always use this app for this kind of file.
This works great! I was able to boot the CentOS system and
install it with no problems.
Good luck!
