I have to manage about farm of 30 virtual machines the farm is hosted on two severs, it consists of windows, linux and solaris OSs. I use VirtualBox for virtualization.

I did all setup manually, if I need to apply changes I again do this manually and this is real hell.

So now I'm looking for a way to automate this. I have a few gold images of OS, if I need to setup new machine I clone it, then I setup new network setting for it manually and setup test demon. if I need to change test environment I have to change gold image, then remove all test machines and clone gold images and again configure network and setup test demon and all I need to do manually.

Can ovirt to help automate this scenarios?

I would say oVirt is part of the solution - the other part is to use configuration management to provision test VMs rather than golden images/templates - updating templates is always going to be manual and cumbersome. There are a few ways to provision VMs - one would be to set up Puppet classes/Chef recipes and provision them using something like Foreman (which integrates nicely with oVirt), another would be to write a Kickstart file which you would pass to an install image to generate a pristine test environment (information here: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/...). If you go the image route, oVirt 3.4 and later has made it easier by implementing template versioning: http://www.ovirt.org/Features/Template_Versions - at boot time you give a template name and version to generate a new VM from a specific version, to update a new version, boot an image off the previous latest, make your required changes, and then save as a new version of the old template. Hope this helps! Cheers, Dave. -- Dave Neary - Community Action and Impact Open Source and Standards, Red Hat - http://community.redhat.com Ph: +33 9 50 71 55 62 / Cell: +33 6 77 01 92 13
