[ovirt-users] An cloud based OVirt Lab for anyone to use and ideally enhance...

[Kyle Bassett]

Hi everyone, I have been playing with latest OVirt the last little while.  I go back with RHEV since the early days when it was in BETA and I was running it in production :} It has certainly come a long, long way...

I see lots of upgrade testing / new feature discussion going on here, I wanted to share it with the community to take advantage of and ideally make it even better.
I plan to integrate this setup with Openstack and add IDM and other features as soon as possible.

If you want to try it out, you don’t need real hardware and still get all the functionally of KVM.
I used Ravello Systems to build it - https://ravellosystems.com - You can utilize the free trial for 2 weeks.

You can find the blueprint here -> https://www.ravellosystems.com/repo/blueprints/64554219

Thanks for helping with the original issues I ran into getting it all working properly.

Here is the description:

A perfect nested lab environment to learn (test upgrades / new features) on OVirt (RHEV) and ManageIQ (Cloudforms) 
I have been testing openstack blueprints from the Ravello REPO quite a bit and saw no-one had build an OVirt setup.
It's been a while since I used OVirt / RHEV (I had been using it since back in the day when when it was BETA!)
I already had an ESXi setup working with ManageIQ / Cloudforms so I figured why not add OVirt / RHEV as well... Openstack will be next...

Here is a blueprint (built on Fedora22) that includes an 2 node OVirt cluster - OVirt Engine Version: 3.5.4.2-1.fc20 (Upstream Redhat Enterprise Virtualization - RHEV)
It also includes a ManageIQ (Upstream Cloudforms) instance to manage / orchestrate the OVirt environment.
Also a Fedora 22 Desktop to use as local management / jumpbox to your environment.

1 OVirt Manager - oVirt Engine Version: 3.5.4.2-1.fc20
2 OVirt KVM Hypervisors
1 Ovirt hypervisor template (used to add more nodes to your cluster)
1 FreeNAS appliance to offer up shared NFS storage for the cluster
1 ManageIQ appliance
1 Fedora 22 Desktop (Configured with VNC access)

Give the services and webui a few minutes to start up after booting.
You will find id/password information in the description of each virtual machine in the Ravello UI. Some vm's required a sshkey.

If you want build you own hypervisor nodes - see some additional steps below (this has already been done on the template I provided).

There’s 2 small issues that you need to work around:

Due to an issue with the the user-mode CPU detection in libvirt, this patch needs to be applied to /usr/share/libvirt/cpu_map.xml. This patch forces the CPU type to be an Opteron G2 independent of the CPUID. To apply this patch, log on to the hypervisor in rescue mode, apply the patch, and then issue the command “persist /usr/share/libvirt/cpu_map.xml”. This needs to be done after step 8 above.

Here is a good blog that details a similar setup for RHEV.

Feel free to ask questions or provide comments

Have fun
