Description Markus Armbruster 2007-01-31 03:02:11 EST

Description of problem:
The PV framebuffer doesn't work on shadow translate mode, because it doesn't
translate gpfn to mfn.  Upstream doesn't need that translation, because the
hypervisor accepts gpfns in 3.0.4.

How reproducible:
always

Steps to Reproduce:
1. Make sure pvfb is enabled (it is by default)
2. Start the pv domain, e.g. with xm create DOMNAME
  
Actual results:
pvfb backend daemon dies during startup.

Expected results:
pvfb backend process runs.
