[ale] VMs sharing native GPU

[Kyle Brieden]

KVM/QEMU and Xen both support PCI Passthrough, but it's been my 
understanding that PCI Passthrough assigns that resource directly to the 
guest/DomU.  Nothing, not even the hypervisor/Dom0 has access to it 
anymore.  I don't think it'll be possible to "share" a PCI device like 
that with multiple VMs running at the same time.
