For populating memory, qemu should probably refill the mapcache on demand. It ought to be catching page faults on access to the mapcache anyway (easy, just need a SIGSEGV handler). If it detects a mapcache access it should first attempt to refill that mapcache entry and if that fails then do something appropriate (crash the domain?). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
