What performance penalty I should expect from the I/O under domU ?
Does it matter to the I/O if the CPU has hardware virtualization ?

no, HVM capabilities let you run non-modified guests, but doesn't do a thing (yet) for paravirtualized guests.

IOW, if you can run something without HVM, having it won't make a difference.
You mean the the HVM will not boost a modified linux kernel ( with xen ) ?
