(In reply to Orit Wasserman from comment #6) > Can you try to reproduce with the latest rhel7 qemu version (1.5.3)? Re-test the bug on the following version with the same steps in comment 0 and the command line in comment 5. Still can reproduce. Tried about 10 times, reproduced 3 times, guest always stuck on some point although the migration completes. qemu-kvm-1.5.3-24.el7.x86_64 kernel-3.10.0-63.el7.x86_64 Does it happen without XBZRLE? (In reply to Orit Wasserman from comment #8) > Does it happen without XBZRLE? I just retest again on the following version with same steps in comment 0: (1) with xbzrle: tried about 12 times, reproduced twice. (2) without xbzrle: tried about 12 times. can NOT reproduce.
