AFAIK paravirtualising Ubuntu is troublesome and requires a little work 
a the moment (a kernel patch and so on), so we did a quick test 
para-virtualising the standard "Oracle Enterprise Linux 5 64-bit" 
provided by Oracle, on top of Oracle-vm and running the same benchmarks.
Results were sligthly better but still far from our expectations. Disk 
writes around 10-15 MB/s.
My doubt is: should we expect much better results (and by consequence, 
there is a big misconfiguration/mistake somewhere in our stack) or these 
results are typical and unexceptional for this kind of systems?
