I have a similar setup. I solved it by writing a small daemon that syncs
system time from RTC time if the error is larger than 10 seconds. This
guarantees that my VM time will be in sync with the host very fast. If
I'd run ntpd it would take minutes for the resumed VM to notice that
something happened.
