While investigating the problems with my Cosmology VMs I discovered that they were all Docker-related.

So what is it and how do you use this Docker? I d/l and installed it but Cosmo is still as slow as a dog.

VMs are always slow it seems (I have a Rosetta VM running for more than two days and the VM itself reports that it hasn't run 12 minutes yet...),
but the name of the app is: camb_boinc2docker (vbox64_mt), so something tells me that Docker is involved.
Installing it solved for me -for Cosmology@Home- the VM Hypervisor sh!t that accompanies vbox apps...
If you check the output of a completed WU you'll see Docker files and settings getting mentioned several times.

BTW: the Cosmology VMs run pretty fast (4 min. on a Ryzen 3 3100 under Linux, 25 min. on a Linux AM1 system, 34 min. on a Windows AM1 system) when compared to Rosetta Python ones (I have two of 3 days and counting -and already over time 20 hours, respectively 1 day)....

We're doing great at Cosmology at the moment! We'll pass LinusTechTips_Team in Cosmology@Home marathon-wise on 27/11/2021 15:00 (CET) (https://formula-boinc.org/projets.py?lang=&prj=12&year=2021) and, since they do not participate in this sprint (https://formula-boinc.org/sprint.py?sprint=22&lang=&year=2021), we close the gap with LinusTechTips_Team (https://formula-boinc.org/index.py?lang=&team=3&year=2021) with an additional 10 or 12 points. Meisterkuehler.de Team and Crunching@EVGA arent sitting on their hands though, and passed us again after being overtaken.

This -in a part of the Stderr output message- is what makes me think Docker is needed

The computer in question ran 317 VM tasks during the sprint, of which only two errored out.
