Question - if oVirt goes down... do the ovirt-nodes and VMs remain up?

Keith, how would you set yourself up with these specs:

2 host servers (quad-core xeons with 32gigs of ram)

Starting to think there is no way to achieve HA with this setup? oVirt requires a dedicated machine?

Thank you!


PS. Could oVirt be integrated into ovirt-node on every server?

Hi Alan,

I have oVirt running in a VM off my Desktop (Fedora 17 w/ KVM & Virt-Manager) off my iSCSI NAS.

I've attached Server #1 as my first host (it's running ovirt-node).

In the process of setting up my storage domains. I have a few questions to the experts out there:

1) How do I add my CD .ISOs to setup new VMs? Create iSCSI storage domain? But then how do I copy my ISOs to it?
Create an ISO storage domain and use the ovirt-iso-uploader to add your ISOs and .vfd files into that domain.

2) Can I run my oVirt VM from ovirt-node machine, without running it in oVirt (ie. setup iSCSI in virt-manager (as it is now) and run oVirt from virt-manager... then I can manage my hosts through that ovirt VM?
Huh?  You could run the oVirt Manager from a VM managed by virt-manager... yes.  Running the oVirt manager inside a VM on a hypervisor (ie. ovirt-node) controlled by that same manager isn't supported AFAIK because the mgr. could get fenced. 

To summarize, you can pretty much run the oVirt manager on any supported OS as long as that OS instance isn't running on a hypervisor (ie. ovirt-node) controlled by *that* manager.

If you haven't noticed the vocabulary to describe the various components can get a little confusing. ;) 

Not sure if I'm making myself clear... but I'm making progress. I think as long as you are not managing your oVirt vm through oVirt itself, the solution should work fine! Just trying to see if I can get that done on an ovirt-node machine...

Thank you,

What you're saying is that I should just run it seperatly and not manage it with itself (oVirt)? keep it on my shared storage so that I can run it off any of the 2 servers? But not manage it with oVirt (itself). I think I'm starting to get it now...
I really appreciate your help!

Nic, how did you make out with this?  I'm looking to do the same thing and am wondering if there is any risk in running the engine on a VM managed by the same engine, as you were suggesting before.  Did you give this a shot?

Itamar, why did you steer Nic away from this?
