Hello everyone,
from time to time I have to pause some Windows machines (hibernate, free resources). If the pause is longer than 48 h Windows refuses to sync the time via NTP in the default settings. Is there a way to force this outside the VM? With Linux there was a solution by reading the hardware clock. I have not found anything for Windows. The documentation of the qemu agent has some switches, but I could not find out how to activate them (build or config)
If there is a general solution (also for Linux) would also be helpful.

Thanks a lot
