I've managed to pick up a 4-core VM on both a Windows 10 and an Alma 9 Linux box. Both are being held back because of a running 4-core -dev task.

Stop that kind of comments!
You have been told the facts.
Blaming people here for things you don't understand or accept is not respectful nor does it solve your complaint.

I have nvme SSDs, nothing specical just what came in the Lenovo from the factory, its like the OEM version of the 980 PRO. It could be, however, after startup they don't normally all finish/start at the same time?

Apologies, I forgot to reply.
That was indeed the problem. Thanks.

VirtualBox apps keep complex configuration problems away from volunteers who can't deal with them.
All because you didn't install (and configure) a local CVMFS client.
Perhaps the solution is not to require oddball filesystems and configurations from the users? To my knowledge no other project requires this junk. Or if they do, they handle it well like Rosetta so I don't notice it.
As for my errors on windows, I had about 8 tasks fail on lasts nights reboot at roughly 10 hours per task already run. Just like I said. 80 core * hours lost.
None of those things are *required*. They're a choice we the users make to run the native application instead of the Virtualbox one. While I have a number of errors in my history I also accept that the vast majority are my own fault, usually from playing around trying to make things work "better" but instead making them worse.
As for your errors on Windows, just because a work unit has clocked up any amount of time (wall-clock time) while active doesn't mean it's been using the CPU for that same time. They're tracked separately for a reason.

new new tasks since last night :-(sorry, should read "NO new tasks ..."
Tja, I was waiting to see if Daniele's multi-core workflow would spawn new jobs, in case my old one was holding it back. Turned out not to happen, so I'm submitting smaller job batches until we work out how to get the multi-core jobs into the system. There may be intermittent disruptions over the next few days if my sleep cycle disagrees with the job queues' needs for attention.

This morning CMS is running OK for me. I re-started CMS about 1 hour ago, it's working fine now :-)

Can this problem with getting a proxy credential from LHC be avoided by installing a local proxy server?
If so, how would one go about this in Linux?
In this case, the two meanings of the word "proxy" are quite different. The proxy credential is an authorisation to connect to the service; the (squid) proxy server is a caching server that saves requested files so that they don't need to be transported again if re-requested.

within the past hour, my hosts have started producing tasks which finish after some 25 minutes.
Seems that no jobs are available again :-(
here an example:
https://lhcathome.cern.ch/lhcathome/result.php?resultid=406083580
Edit: the automatic stop of tasks distribution worked this time, with the server status page showing "0" unsent tasks :-)
Yes, I caught up on that last night, missed it yesterday.

Still not fixed.
I'll remind Laurence of this -- my current job does show output for all other Alt-Fn (n=1-6).. Also the running.log isn't being refreshed in the "show graphics" web page.

Seem to have sorted it, adding an override file didn't seem to work but after some searching here editing this file /etc/systemd/system/multi-user.target.wants/boinc-client.service and changing ProtectSystem=strict to full seems to have fixed it, ill keep an eye on outputs.

I have reset the project and cleared out any old entry on Vbox and the units still instantly fail, honastatly with CMS and Theory failing on Linux for me and now this I am tempted to give up on the project :(
Example task https://lhcathome.cern.ch/lhcathome/result.php?resultid=405102137
Looks like the key points are :
VBoxManage.exe: error: Cannot close medium 'E:\Boinc\data\projects\lhcathome.cern.ch_lhcathome\CMS_2022_09_07_prod.vdi' because it has 1 child media
