[one-users] Dynamic resource reallocation

[Antonio Carlos Salzvedel Furtado Junior]

Thanks for replying.

That's bad. I've been reading about the libvirt API, and I found out that
it does support dynamic resource reallocation.
I took a look at the libvirt driver for OpenNebula, but I think the
reallocation can't be done over OpenNebula.
Maybe I could work with libvirt somehow..
