[Xen-devel] Re: What is more secure? HVM or PV ?

["David Pilger" <pilger.david@xxxxxxxxx>]

Let me rephrase my question -
What are the attack vectors for each architecture?

For PV it's the Paravirtualization API and hypercalls, and for HVM
it's the VMEXIT Parsing / QEMU states and hypercalls...

Are there other attack vectors that may be used to hack from a domU or
HVM into dom0? can we get an obvious conclusion about which
architechture is more secure? PV or HVM?

Thanks,
David.
