A bit confused with "free Linux/Ubuntu VMs".<br>
Do you mean you looking for VM image ( to directly run your tests )<br>
or an emulator to create VMs locally and play around.<br>
<br>
For the first, I have not tried with. Probably vmware images can be found at :<br>
<a href="http://www.osboxes.org/vmware-images/" rel="noreferrer" target="_blank">http://www.osboxes.org/vmware-<wbr>images/</a><br>
<br>
But, if you are looking for emulators, I would say Xen and Virtualbox.<br>
I use them for most of my development for linux kernel related work<br>
items. To start with, I would suggest you to start with Virtualbox.<br>
Its easy to begin w.r.t. configuration, installation and other items.<br>
