You need to setup a serial console in order to provide the boot log. The
following wiki page should contain all the information needed in order
to set it up:

No, but the Xen PVH ABI is still not set in stone, so backwards/forwards
compatibility is not guaranteed. Either 3.17 or 3.18 should work fine.

I don't have any performance figures yet. PVH is very experimental and
the focus right now is to make it stable and implement the missing features.
