Hi Shimada-san,
This change appears to prevent pci passthrough from working
correctly on an HVM doman on an HP dc7800 in x86_64 mode.
Actually the HVM domain in question fails to boot.
I my test environment is:
hypervisor: xen-unstable.hg cset 19174
(anything after that up until 19210 (tip) doesn't boot on
my machine, I am investigting that issue, which may be related)
tools: xen-unstable.hg cset 19210 (tip)
ioemu-remote: qemu-xen-unstable.git
8c771eb6294afc5b3754a9e3de51568d4e5986c2 (this patch)
I'm happy to look into this, but I am wondering if anyone else
has seen this problem.
