Hi,
I'm currently planning to setup
a libvirt-vm to use as ovirt-engine.
OS in the vm would be EL 6.5
Does anybody have any experience with
such a setup?
I'd also like to know if such a setup
could be easily ported to the upcoming
self-hosted engine feature or if a physical
setup could get ported better?
Thanks for any input!

Basically there should be no problem to install RHEVM on virtual machine so it should work
ok.
Also there is no difference between migrating existing RHEVM that runs on physical machine
or on virtual machine.
You need to backup your existing DB and restore it on engine vm. See the following wiki
page for detailed explanation:
http://www.ovirt.org/Migrate_to_Hosted_Engine
Thanks,
Leonid.

Hi Leonid,
thanks for pointing that out.
Actually, I was already aware of the wiki page
but it just mentions Fedora so I was curious
if someone did this on EL 6 ?
Maybe someone else can add his own experience.
If not, I will update the wiki with my own findings
when I start experimenting with it.

I recently used that procedure for a centos install and it worked for
me. We used a slightly different backup but in essence it is correct.
Backup pki stuff, backup database en restore pki and restore database
with the script in /usr/share/ovirt-engine/dbscripts.

Did you have problems with engine-backup? Or had other reasons to not use it?
Thanks!

I currently need to move an AIO configuration from AMD hardware to Intel
I7 hardware. The engine-backup WIKI discusses backups, but not
restores. I am a bit concerned about using engine-backup to restore an
AIO configuration to a different system as another WIKI page with
step-by-step instructions to do what engine-backup does for you,
mentions you have to do some extra steps if you are changing hostnames
as the hostname of the ovirt-engine is embedded in the database.
There really needs to be some work done in Ovirt on making it easier to
import existing disk images and just generally moving things around
without having to bounce off an NFS server.
Should I do a BZ on that?

I didn't try that. In principle it can. Note that it will only backup/restore
the engine - not local storage domains (ISO or data), VM images, etc.
If you try that, please report back. Thanks!

Note that you do not need to have the hostname equal to the "fqdn" input
during engine-setup - this last one just needs to be dns-resolvable and
point to the machine intended.
Also, there is another utility to do that, called ovirt-engine-rename -

Sorry for going slightly off topic, but how is everyone's hosted engine
deployment going? Are you restricted to NFS?
I tried the migration procedure last month and it worked.. but had quite a
lot of issues so I ended up reverting back. I didn't open any bugs in the
assumption it was in super alpha stage.

Andrew, in general I get positive feedbacks from RHEL users. For Fedora
and other distros, this should be in a better situation in the following
1-2 weeks when we'll have 3.4 beta available.
I'd love to get your feedback on it.
I tried the migration procedure last month and it worked.. but had
quite a
lot of issues so I ended up reverting back. I didn't open any bugs in the
assumption it was in super alpha stage.
Next time please open bugs... That's the best way to improve the project,
regardless of the version state. If unsure, you can always try irc / this list
first to see if this is a known issue and if there are workarounds.

I missed your NFS question, sorry;
Yes. Currently we have NFS limitation and we will do our best to see
if SAN can be added. Note that time is not on our side for 3.4.

Hi,
so just for clarification:
self hosted engine is just supported via NFS-backed Datacenter, once it
is released?
I didn't saw that mentioned on the wiki page of the feature or anywhere
else, can someone update the documentation accordingly?
(I would do it myself if I'd knew exactly what the limitations are).

Hi Sven,
please take a look at: http://www.ovirt.org/Features/Self_Hosted_Engine#Limitations
This is there for quite some time.
May I ask which page are you using?
Doron
4:38 p.m.
Hi Doron,
I'm very sorry, I just didn't see it.
The page is very long, so maybe we can
divide this page into several sub pages for
better readability?
Thanks for pointing me in the right direction!
And a question:
"Only one VM is deployed and managed by HA daemons (support for
additional VMs to be added at a later stage)."
What does that mean? The ability to self-host multiple engines
at a time, or a different HA-Setup with two active/active or
active/passive vms?
Something else?

Hi Doron,
I'm very sorry, I just didn't see it.
Not a problem. I agree this page can
be improved.
For this is the reason I created the simplified
http://www.ovirt.org/Hosted_Engine_Howto
As you can see it provides the basic installation
flows and explanations.
The page is very long, so maybe we can
divide this page into several sub pages for
better readability?
Sure.
Would you like to try and we'll help?
Thanks for pointing me in the right direction!

The idea is to allow other types of HA VMs, running something
else. for example, let's define a profile of a VM running a DB.
This means we may need to monitor other resources than we would
do for hosted engine VM. So this requires some more work...

Andrew, in general I get positive feedbacks from RHEL users. For
Fedora and other distros, this should be in a better situation in the
following
1-2 weeks when we'll have 3.4 beta available.
I'd love to get your feedback on it.
I missed your NFS question, sorry;
Yes. Currently we have NFS limitation and we will do our best to see if SAN can be added.
Note that time is not on our side for 3.4.
Is there support for glusterfs with
libgfapi?

Next time please open bugs... That's the best way to improve the
project, regardless of the version state. If unsure, you can always
try irc / this list first to see if this is a known issue and if there
are workarounds.
Sorry about that, I thought it was still very dev style I didn't want to flood bzs
with things that are already being worked on.

Is there support for glusterfs with libgfapi?
Currently not sue to some gluster issues we had.
Adding Sahina to shed some more light (if needed).

Yes. Currently we have NFS limitation and we will do our best to see

worth mentioning you can use hosted engine on an iscsi/FC cluster - just
the hosted engine VM needs to be on NFS

Awesome!
Is it worth while trying it now, or should I wait for 3.4 beta?

well, we'd love input as early as possible - maybe with the 3.4 alpha
which should be out any day now.

Can engine-backup be used to move an AIO

I didn't try that. In principle it can. Note that it
will only
backup/restore
the engine - not local storage domains (ISO or data), VM
images, etc.
If you try that, please report back. Thanks!
I currently need to move an AIO configuration from
AMD hardware to Intel
I7 hardware. The engine-backup WIKI discusses
backups, but not
restores. I am a bit concerned about using
engine-backup to restore an
AIO configuration to a different system as another
WIKI page with
step-by-step instructions to do what engine-backup
does for you,
mentions you have to do some extra steps if you are
changing hostnames
as the hostname of the ovirt-engine is embedded in
the database.
Changing the hostname is specifically not in the scope
of engine-backup.
Note that you do not need to have the hostname equal to
the "fqdn" input
during engine-setup - this last one just needs to be
dns-resolvable and
point to the machine intended.
Also, there is another utility to do that, called
ovirt-engine-rename -
see this for details and implications:
http://www.ovirt.org/Changing___Engine_Hostname
<http://www.ovirt.org/Changing_Engine_Hostname>
There really needs to be some work done in Ovirt on
making it easier to
import existing disk images and just generally
moving things around
without having to bounce off an NFS server.
Should I do a BZ on that?
Not sure what you mean exactly, but you are always
welcome to open BZs on
bugs/RFEs...

Andrew, in general I get positive feedbacks from RHEL users.
For Fedora
and other distros, this should be in a better situation in
the following
1-2 weeks when we'll have 3.4 beta available.

I tried the migration procedure last month and it
worked.. but had quite a

Hi Leonid,
thanks for pointing that out.
Actually, I was already aware of the wiki page
but it just mentions Fedora so I was curious
if someone did this on EL 6 ?
Maybe someone else can add his own experience.
If not, I will update the wiki with my own findings
when I start experimenting with it.

Basically there should be no problem to install RHEVM on virtual
machine so it should work ok.
Also there is no difference between migrating existing RHEVM that runs on physical
machine or on virtual machine.
You need to backup your existing DB and restore it on engine vm. See the following wiki
page for detailed explanation:
