[Xen-devel] hvm_domain_use_pirq() breaks device passthru on xen-4.1

[Wei Huang <wei.huang2@xxxxxxx>]

Hi Stefano,

The recent patch you put into xen-4.1-testing.hg broke device passthru 
on Windows. I bisected the changesets and it turned out to be 23092. The 
NIC can't get the IP address correctly. Changset 23091 worked fine.
Regarding your patch, do we need to differentiate pv-on-hvm guests from 
others? The Windows VM I used is unmodified. I think 
hvm_domain_use_pirq() returned an incorrect answer for such guests.
Thanks,
-Wei
