[one-users] Moving away from vmware, here are my modifications

[Ruben S. Montero]

Hi Tiago

THANK YOU VERY MUCH for your great feedback and for this patch. We
want to put the vmware driver functionality on a level with the Xen an
KVM ones for the next releases, so this is very timely....

Thanks again for your contribution!

Cheers

Ruben
