Re: [Xen-users] two simple questions...

If you intend to run linux guests, you can run them in PV mode and
share pci/pcie card like you want, provided you have open source

if you run other OS or have binary drivers you have to run in HVM mode
where all pci devices are supposed to be lumped together on intel
platform, while pcie devices on intel and both pci and pcie devices on
AMD can be given out independently.

That's the theory.

In parctice I was unable to get onboard pcie usb3 controller to work
in HVM guest or intel gpu in PV dom0.  I recommend you read up on your
target pci/pcie devices, perhaps someone tried this already.

as far as specs go, it's advisable to dedicate a core per guest plus a
core for dom0. you can have more guests if they are idle of course.
you could get by with little memory too, it really depends on what you
are running. If you are going HVM route you'd need a pretty recent
motherboard and processor though, as it need IOMMU.

btw, if xen doesn't work out for you, you can try other options, e.g.
virtualbox has a pci passthrough module.
