Installed Whonix (188.8.131.52.1) in KVM on debian 8.5 following https://www.whonix.org/wiki/KVM quite closely. But after starting the Whonix gateway and running whonix check I get the error:
[quote]PVClock Test Result:
Unwanted PVClock kvm-clock acpi_pm detected! Using this PVClock together with whonix is recommended against, because it conflicts with Whonix’s TimwAnc design .
If you know what you are doing, feel free to disable this check. Create a file /etc/whonix.d/50_whonixcheck_user.conf and add:
- If you are using KVM, you probably did not follow Whonix’s KVM instructions. 
The Gateway does indeed has kvm-time installed/active and no timesync installed. The Workstation does has timesync and it works as was used to with VirtualBox.
Wondering what went wrong with the install and how this problem can be fixed in a safe/secure manner. KVM-time instead of the normal timesync seems to be a serious risk for anonymity (linking host time to Gateway).
