lost ticks in linux: msg#00167

Subject: lost ticks in linux

Hi all,

Just recently started playing with kvm and used my
linux image which was previously running with
vmplayer. From what I can tell so far kvm runs
noticeably faster compared to vmplayer on the same
image.

The only issue I've seen so far is with the timer - I
get lost ticks, which was not a problem with vmplayer:

...
TSC appears to be running slowly. Marking it unstable.
Time: acpi_pm clocksource has been installed.
...

I don't have this problem if I run it without loading
kvm-intel.

Also would appreciate suggestions about the kernel
config inside KVM - CPU etc.

My CPU Core Duo E6600 btw.

Thanks,
Emil
