[Xen-devel] how to determine whether 2 virtual guests are on the same physical machine
Hi folks, I wanna find out the most convenient way for the following question: ***Give me any two virtual guests, are they on the same physical machine?*** I guess there must be some common variables that guests within one physical host are sharing, but as far as I know, xenstore cannot give me feasible answer(I have checked all the entries in xenstore, NONE is unique among physical hosts). So I am trying to look for some pointers, like page table beginning address, dom0 net_device pointer, but seems they are not accessible from vm guests. My question is : are there any system unique pointers that guests could get access to? Thanks, -Jian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
