You might get better results with chrony or RADclock than ntpd.

I expect there's a way for the guest to be notified that it's been
resumed and run a command, you might want to ask here:
http://www.linux-kvm.org/page/Lists%2C_IRC

However, the following suggests NTP with "w32tm /resync" - I expect you
could use that or "net time \\hostname /y" in a recurring at job.
