1. Ok, thanks.
2. I didn't understand how the PCI probing of a HVM is being done, if no new files were introduced to the hvm source tree (vmx). would you be kind to explain?
The README states that we get 4 modules by doing so, that are needed to be loaded in a certain way (platform-pci first), so I guess that should be done in dom0. It's kind of hard to know what to do If you don't know the architecture.
Thanks,
Eric.

I'm not sure. I think they are probably Stevens patches from before they
were merged into xen-unstable.

There is a README in the unmodified_drivers subdirectory which explains
what you need to do.
It is basically the same as for building any out of tree driver:
cd unmodified_drivers/linux-2.6
sh mkbuildtree i386
make -C /path/to/kernel/source M=$(pwd) modules modules_install
The kernel source is usually pointed to by /lib/modules/$(uname
-r)/build if you have the relevant kernel-headers package installed or
if you built the kernel yourself.
Ian.
