I can't understand why clock in guest OS (Windows 2003) goes very slow.

Host OS: Debian GNU/Linux Etch x86_64 (kernel
Host CPU: something like Intel Core Duo
$ cat /proc/cpuinfo
processor       : 0 # and 1 too
vendor_id       : GenuineIntel
cpu family      : 15
model           : 6
model name      :               Intel(R) Pentium(R) D CPU 2.80GHz
stepping        : 4

qemu version: snapshot 24.01.2008, compiled with GCC 4 for target x86_64-softmmu

"Stable" version in Debian Etch is 8.2 works not very stable - but clock get lost only sometimes, when host CPU is busy. Snapshot works more stable - clock is constantly slow, even M$ NTP server (Windows Time) can't help.

I can't find, how to debug this problem.
