I believe I have the same problem, place a guest under any amount of load, let's say 'yum upgrade' and the network stack goes out to lunch for 1-5 seconds. Here is a sample of the ping statistics (host to guest) from doing such an operation on a 3.13.0-30.55 kernel:
213 packets transmitted, 213 received, 0% packet loss, time 211998ms rtt min/avg/max/mdev = 0.136/106.283/2651.359/428.403 ms, pipe 3 And a 3.11.0-19.33 kernel: 62 packets transmitted, 62 received, 0% packet loss, time 61074ms rtt min/avg/max/mdev = 0.189/0.434/1.987/0.228 ms -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307473 Title: guest hang due to missing clock interrupt To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1307473/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
