Cuda + Virtualization

If I were to install ESX would my xp virtual machines be able to access the GPU?

no, they would not

Are there any plans for this to be supported in the future?

Not in the short term.

Check XEN and HYPER-V

It might be possible. Check out the e-mail thread below – the thread gets interesting towards the end

Look @ the Hyper-V along with the operating systems mentioned above.

Note Hyper-V also supports Linux as a Guest OS (so says my memory). Check the microsoft site
