How is this different from bug 803186, is the only difference in removing virsh migrate-setmaxdowntime command from the loop? This is very likely a dup of that bug but I'll wait for the additional info before closing it. I report it because the bug 803186 is reported on rhel 6.2 but I can only reproduce this bug on rhel6.3, and on rhel6.2 concurrent migration will not cause virsh command hang It's a race so you were not probably lucky enough to hit it on rhel6.2. I wasn't able to reproduce this bug even on rhel6.3 (until I saw the backtrace and logs). *** This bug has been marked as a duplicate of bug 803186 *** Please have a look at bug 803186 comment 17 |
