From 70fedd76d9fe4900651f3360725fb511a19d03d5 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 14 Jul 2010 13:36:49 -0600 Subject: kvm: Don't walk memory_size == 0 slots in kvm_client_migration_log If we've unregistered a memory area, we should avoid calling qemu_get_ram_ptr() on the left over phys_offset cruft in the slot array. Now that we support removing ramblocks, the phys_offset ram_addr_t can go away and cause a lookup fault and abort.
