From b533f658a98325d0e47b36113bd9f5bcc046fdae Mon Sep 17 00:00:00 2001 From: Mario Smarduch Date: Wed, 19 Mar 2014 10:24:26 -0700 Subject: fix return check for KVM_GET_DIRTY_LOG ioctl Fix return condition check from kvm_vm_ioctl(s, KVM_GET_DIRTY_LOG, &d) to handle internal failures or no support for memory slot dirty bitmap. Otherwise the ioctl succeeds and continues with migration.
