[ovirt-users] Setting up all-in-one

Tue Jul 29 02:22:44 UTC 2014

Hi folks,

I'm new to the project, so please pardon my ignorance.

I came to oVirt by way of looking for a suitable KVM/libvirt-based IaaS 
stack to supersede my old Ubuntu 12.04 setup, that I've been running 
since KVM came to Ubuntu-town.

I've looked & tried a number of solutions - Eucalyptus, Enomalism, 
OpenStack - but most proved too cumbersome or admin-heavy for us.

A while back I set up oVirt on CentOS (whatever was stable at the time), 
but had to shelve the project for a while, because... reasons. Fired it 
back up again & did all the requisite updates/upgrades to bring the host 
up to snuff.

Unfortunately oVirt did not work as well, so I tried removing/purging it 
from the host & reinstalling it - both the 3.4.* stable & 3.5 beta - but 
both get hit up by the same issue when running the engine-setup.

Details follow -

I've had a dig around & from what I can tell this (possibly) related to 
bugs that would've been patched in the stable release (& beta?) that 
I've installed, but the issue persists.

I'm not certain where the issue could be coming in (lower-level/OS 
dependency maybe?), or if I've missed something.
I've flushed & reloaded the full stack already, with the same outcome. 
Next I'll have to wipe the OS & start again, with no guarantee this 
issue won't reoccur.

My next step would simply be to try out the oVirt live image.
Does the image provide an option to install to the host? (looking at the 
live node installers, it seems likely)

Are these images *purely* for PoC/demo/testing (i.e. highly unstable), 
or would it be stable enough for in-house (Docker) prototyping before 
deploying to a hosted/stable/production environment?

Cheers
