Any suggestions how vmware or other virtualised environments do this, or is this even possible ? Any pointers to the code is appreciated. (Sorry no locking/synchronisation solutions pls).
I am not 100% sure, but either virtualization use LDT, or utilize shadow page in certain ways. So the idea is, each process/thread has their own "page table descriptor", therefore each of them has separate protection mapping. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
