[Xen-devel] Question regarding to the uniqueness of xen's grant table mechanism

["Lily Huang" <ushuanglily@xxxxxxxxx>]

Hi, I am writing a paper related to Xen. I want to know whether the grant table based memory sharing mechanism is only available on Xen platform. Do other virtual machine systems like VMWare, Disco, or VirtualPC have similar mechanism to share memory across domains?
Also, does HVM support the grant table mechanism?

Thanks,
lily
