only fast enough to host at most one or two virtual machines.
I personally haven't had a chance to play with all of this yet but
Condor is very quickly becoming a VM-friendly tool. Check out this
presentation from Condor Week 2007:
Condor can launch jobs under VMs for you. And as with all Condor
installs you can tell Condor "only run X number of jobs concurrently on
this machine". So you get to tell each machine now many concurrent VM
sessions to allow.
This is something we are actively looking at. In fact we were basically
waiting for this sort of functionality to become available since it
makes the whole business of provisioning the required, compliant
environments for high throughput computing tractable. Very much what the
We have looked at using VMWare as the VM engine, since it has the widest
ability to run almost anything (or what users will want in terms of
OSes) on the widest variety of underlying machines (or most of what we
have to run on.). This having been said I am fairly agnostic, provided
the VM engine offers the required features at a good price, as the
important thing is to facilitate the users.
We've also been doing some work on efficiently provisioning virtual
machines (vmware) to clusters, and so on, although we need to revisit
this work and test against VMWare's own products for provisioning.
