Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Thomas Tuttle (thomastuttle) Assigned to: Nobody/Anonymous (nobody) Summary: Guest clock runs at 2x host clock Initial Comment: (This question was already mentioned on the mailing list <http://sourceforge.net/mailarchive/message.php?msg_id=38063609> but, as far as I can tell, a solution was not found.)

For example, if I run `sleep 10', it only sleeps for 5 real seconds. And `watch -n 0.1 date' clearly shows the clock running faster than normal. As you can see, I've properly set rtc/max-user-freq to 1024 on the host before I started the virtual machine. I've tried passing `notsc' and/or `clock=pit' to the (64-bit) guest kernel, but that doesn't help. I am going to try rebooting my machine with only one core enabled, to see if perhaps that fixes the problem. (It's just a hunch, but it's worth a shot.)
