Yes, I did note the new Security tab. I do realize you face limited time and resources, yet it is unfortunate Whonix does not have a dedicated VBox maintainer. I say this because the VBox user base is likely much larger than the combined number of KVM and Qubes users, by a significant factor. I also doubt this VBox user base disparity is likely to change any time soon.
I am pretty sure a new VBox topic such as 'Whonix VBox Paravirtualization - Which Acceleration Mode is Optimal? Help Us Test!' is warranted at this point.
I do not want to presume which testing information would prove the most useful for you to make a VBox determination.
However, I imagine you would want VBox users to report:
- Host OS name: Win 10, Gentoo, etc.
- Host OS architecture: 64 or 32 Bit
- Gateway Version - only 11, or better.
- VBox Acceleration Mode Used
- Notable Observations - errors, warnings. slowness, failures, etc.
- Any other 'things' you deem important.
It is probably best to create a short form that users can fill out with the requested information so you don't have to hunt through long text 'essays.'
Once the Gateway performance is understood across a range of systems, then you could open testing up for the Workstation, if desired.
To close, another loop, I am now running Gateway 11 under Acceleration = None.
No errors, no warnings, and apt-get works. However, just after the apt-get scan began, the Gateway reported:
hrtimer: interrupt took xxx ns
I don't know if that is significant, or not.
In any event, the Gateway is operating correctly under Acceleration = None, and if any 'slowness' is in fact occurring, it is imperceptible. Perhaps there is some kind of relevant speed test?
Food for thought.
