[Xen-devel] Is there anyway to let two hvm Domain share memory?
Hi, everybody: Currently I am thinking on that is there any way to let two different hvm guest domain share the same memory in Xen? If we can do this, It will be a great improve to inter-domain communication on the same physical machine. If you have any suggestions, Please let me know. Thank you in advance. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
