Re: [Condor-users] Condor in virtualized environment

[Steven Timm <timm@xxxxxxxx>]

Look in the presentations of Condor Week 2010. There are a couple worked
examples, both of which used VirtualBox, I believe.  Also one from earlier
that ran COLinux on top of Windows without benefit of hypervisor.

Fermilab has done a lot with Xen hypervisors but the kernels with Xen
hypervisors built in don't always play nice with all the latest and 
greatest graphics cards.  not the choice for an opportunistic student lab.

I was wondering whether anybody had a Condor use case where a solution to this cross-platform requirement had been addressed?

The machine would then look transparently like Windows to the student, whilst maintaining the capability to run Linux jobs via Condor under the hood.  However, I don't know how to achieve this kind of looped-back desktop virtualization!
