Summary: guest clock runs 2 times faster than the host clock

Initial Comment:
Host: 
 processor: Intel(R) Core(TM)2 Quad CPU           @ 2.66GHz
 OS       : debian squeeze
 Qemu     : qemu-kvm-88 
 Kernel   : Linux bcv 2.6.35.3 #1 SMP PREEMPT Mon Aug 23 17:55:19 BST 2010 x86_64 GNU/Linux
Guest:
 processsor: Intel core2duo smp 2
 OS        : SUSE linux enterprise 10 64bit

so running a 64 bit OS on 64 bit debian host.

The clock runs double fast than the host OS. This results in guest gaining time and going ahead the host

Message:
Come on, kvm-88 is ancient unsupported development snapshot. It isnt' even
an alpha version.

Please try current code (at least qemu-kvm-0.12.4 as available on
backports.org) and file a new bugreport if the problem is still here.

And if the issue _is_ present in real version, please file a bug in
launchpad.net against qemu project, not here.  This bugtracker is dead.

Thanks.

Message:
Running a 32 bit OS instead of the 64 bit OS maintains time properly. It is
just that running the 64 bit OS inside this qemu-kvm makes the guest to
gain time.
