[Users] virtualized engine / port to self-hosted engine
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! -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

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. ----- Original Message ----- From: "Sven Kieske" <S.Kieske@mittwald.de> To: users@ovirt.org Sent: Monday, January 6, 2014 12:47:23 PM Subject: [Users] virtualized engine / port to self-hosted engine Hi, I'm currently planning to setup a libvirt-vm to use as ovirt-engine.

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. Am 06.01.2014 11:58, schrieb Leonid Natapov:

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! -- Didi

Can engine-backup be used to move an AIO configuration from one host to another? 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!

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

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
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? Am 09.01.2014 15:24, schrieb Doron Fediuck:

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!
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?
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...

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
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...
Best regards, -- Didi
Sorry for going slightly off topic, but how is everyone's hosted engine deployment going? Are you restricted to NFS?
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?
Currently not sue to some gluster issues we had. Adding Sahina to shed some more light (if needed).
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.
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.

Can engine-backup be used to move an AIO configuration from one host to another?
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.

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

I did a migration from existing RHEVM to hosted engine vm. Both were on RHEL 6.5 ) ----- Original Message ----- From: "Sven Kieske" <S.Kieske@mittwald.de> To: "Leonid Natapov" <lnatapov@redhat.com> Cc: users@ovirt.org Sent: Monday, January 6, 2014 2:53:06 PM Subject: Re: [Users] virtualized engine / port to self-hosted engine 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. Am 06.01.2014 11:58, schrieb Leonid Natapov:
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
