I have occasionally seen "Job Unmanageable" messages, but they usually occurred when there were reboots before the VBox app had time to close the jobs and settle down. Hopefully, I won't find new ones occurring. I believe that the current BOINC package includes VBox 6.1.12, so hopefully a downgrade to a Vbox 5 version won't be necessary. Let's hope it all continues well.

I downloaded/updated VirtualBox to 6.1.26 and that appears to have solved my problem. You are certainly correct about needing all pointers to be consistent. And thank you for the correction on Hyper-V.

I have used preferences to play with the number of available threads and the percentage of processing time. At the moment (and for the last 2 months or so) I have ended up with 8 CPU threads plus a GPU running at 45%. This has the largest proportion of processing power that has provided stable temps across all projects and has not evidenced any issues, at least as far as I have noticed while monitoring production across projects. Raising the runtime percentage consistently leads to temperature elevations in Rosetta and WCG. I assume they pound the processor which causes the problem. This is my first AMD build so it's all new to me but I have already spent my time limit on trouble shooting the temps issue and my current solution seems to have been working for the last 6 months. Should I notice it failing, I'll revisit the issue. This is a secondary app on the box so as long as it works reliably and consistently, it's not worth another 6-10 hours for an improved resolution.

Thanks for your help in getting LHC and Cosmology@Home back up and running. They can now rejoin Einstein, Rosetta and Climate (when they have processing). At least I can get a few more results for those projects.

I'll try the download from VirtualBox but I haven't had good luck with those installs when I have tried in the past. BOINC doesn't seem to know how to communicate with it.

On the CPU throttling, I found that some projects (Rosetta, particularly) were causing my CPU to heat to close to maximum acceptable temperature which was unacceptable to me and this has been my solution for the last few months. I should probably revisit my cooling design, but have not had another round of time for that. It's been working fine for the last few months (since May, I believe).

I'm running Win11 on an AMD processor. I believe Hyper-V is Intel specific and I never install anything but what is in the Boinc releases and all has worked fine for about a decade.

I'm not sure quite what is going on but I just installed the new BOINC 7.16.20 package with VBox 6.1.12. After the combined install I am getting task failures after 17 secs. The job log for on task is below. Several tasks seem to have the same error message set. Am I right that the VBox didn't install correctly? Or is there some other issue with the BOINC package?

I'm running Windows 11 on an AMD based, home-built system. System is several months old and stable. As is the Windows 11 install. Virtual tasks were running successfully
until the new BOINC package was loaded. I run a few different projects and no virtual tasks are running successfully.

Any thoughts?
