The basic requirement in the guest to do what you describe is that
it has hotplug capability and has the driver for the device you want
to assign to it.  All the rest of the requirements are on the host sw
and hw (linux+kvm capable of device assignment, which latest should be,
and hw VT-d or AMD IOMMU).
