I did reproduce this on qemu 1.0.1.
What would you like me to test next? I've got both VM hosts currently running
3.17-rc4, so I'll know tomorrow if that works.
I've been looking into this off-and-on for a while now, and this time around I
may have found other folks experiencing the same issue:
https://issues.apache.org/jira/browse/CLOUDSTACK-6788
That one's a little empty on the details (do y'all know more about to whom that
bug was "known" than I do?), but
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1297218
sees similar symptoms due to running NTP on the host. I may try disabling that
after the current round of testing-3.17-rc4 finishes up.
