[Bug 1307473] Re: guest hang due to missing clock interrupt

[Mike Lowe]

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
