Clocksource: wd-tsc-wd... messages

I am trying to setup OpenWRT on VBox and getting a constant stream of these messages after staring the VM:

clocksource: wd-tsc-wd read-back dealy of 109177ns, clock-skew test skipped!
clocksource: timekeeping watchdog on CPU0: kvm-clock wd-wd read-back delay of 54063ns

I would really appreciate some help in solving this as the messages are making it very hard to do anything. Thanks!
