Hello,I am hacking on a Mini-OS that is able to run as domain 0 and is able to start a guest (another Mini-OS for now). I was able to get a memory allocated to the guest and am now trying to build its pagetable and after that copy the kernel to the right places. The problem is: Given a machine frame number from a memory frame of the guest, how do I conceptionally map this into dom0's address space? I followed the code path from xc_map_foreign_range to some obscure pagetable updates in the Linux kernel, but am still unable to make heads or tails of it. Any help is appreciated. Regards, Julian _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
