Hi,

I had additional questions(I re-read the Assign_hardware...), and I don't
quite follow it completely. The config given is for dom0, it doesn't have
any information as to what domU will get access to this pci device? Do I
need to change config in domU as well, document doesn't say anything about
it. Furthermore, in the document I see references to "xm
pci-list-assignable-devices" cli's, however, XCP comes with xe tool-stack,
does it come with similar pci commands? I am yet to install XCP, but wanted
to check.

Thanks
