From: Kevin Locke <kevin@kevinlocke.name> The comment that

For instance, qemu-ga doesn't support guest time synchronization on Windows guests, but Linux ones.

Was correct at the time, but has since been addressed by qemu/qemu@105fad6bb22, which added support for set-time without a time argument, as used by `virsh domtime --sync` by libvirt-guests.sh. I can confirm that `virsh domtime --sync` works correctly on a Windows 10 guest, as does `SYNC_TIME=1`. (Note that there can be a significant delay between when the command completes and when the guest time finishes synchronizing due to QEMU GA calling `w32tm` with `/nowait`, which complicates testing.)
