Hi Alejandro,

I've been doing tests to compare the performance isolation between
para-virtualized and full-virtualized guests using Intel VT. First of
all we performed tests over 2 VM's (paravirtualized guest). Some bench
stressing memory and disk were done measured by xenmon and virt-top.
These two measure tools helped to determine CPU allocations, blocked
and waited times, and everything worked fine.

I think this is really interesting research. Can you give us some more insight into
your testing methodology?

Are you familiar with the work at Clarkson University regarding performance isolation?
