That sounds like the normal behavior for Virtual Box projects. You can set Max # cpus to get a lower cpu count per task and try Max # Jobs to limit running tasks. You can also control the behavior using app_config.xml method.

Virtual Box tasks run at normal priority and require a bit of time to shut down / save the running VM state. I just exit Boinc Manager and have it kill the processes. Give it a minute or two and then reboot or shut down.

Do you have any other projects that use Virtual Box and are working on that machine?
6.1 series of VirtualBox is the only one supported per the VirtualBox website.
You can try uninstalling and reinstalling or move to the 6.1 version. Try opening VirtualBox and watching the start up of the Theory task. It may give some clues also.

I am just tagging in that I am successfully running CMS tasks.
Four concurrent CMS tasks at a time. No other projects running. No app_config.xml for this project

I have local preferences set to Use at most 50% of the CPUS and 100% of CPU time.

Network is unrestricted

Disk is 100 GB for Boinc
Memory is 85% in use and not in use. Page/swap is 75% limit

Boinc is 7.16.11 and VirtualBox is 6.1.16

Check your project preferences. That error message is showing you have Theory checked and Atlas unchecked. Something may have borked.

Go to your LCH@home preferences. At the bottom is "Max # CPUs", set that to 1 and your Atlas tasks will use one core after you get new ones. You can also max # of jobs, if necessary.
This can be controlled app_config.xml but I had trouble with Atlas, the number of cores and the assigned memory in the past. I think you have to have the cores and memory requirement in the config. There should be posts in the Atlas forum section. I don't know what the current memory requirement formula is.

Maybe a 'tool tip' could be added to the preference "Run native if available?" to explain it's usage. It really is confusing for anyone not well versed in this project.
Maybe change to "Run LINUX native if available?" or give it a mouse over explanation, if possible?

Hyper-V is Microsoft's version of a virtual machine or hypervisor.

I don't think that is the problem here as the computer is showing "Microsoft Windows 8.1

You can try Google Translate for language.

When logged into the LHC website, you click on your name on the upper right side. This takes you to Your Account. LHC@Home Preferences shows what tasks you have selected to run here. I have Theory and Atlas selected. I don't think CMS is working, right now.

Virtual Box related tasks run at a higher priority than normal BOINC task and can slow your computer, no response.

It looks like you are just getting Theory tasks. Try posting in the forum for those tasks. There may be someone that know what your error messages means.

'app_config.xml' is a file you create that helps control the applications in BOINC for each project. It is a bit complicated.

Did everything run okay before adding the LHC project? I looked at a few of your tasks and it may be you're running out of memory for the virtual machine tasks.
Are you only running Theory tasks at LHC?

What do you have set for your preferences and what projects and applications are you running?

Looks like you have 4 cores / 8 with hyperthreading and 8Gb ram.

You can try looking in the Theory forum for ideas but setting your computer preferences to use less than 100% of the number of processors would be a start. You might need to set up an 'app_config.xml' to control this project and it's applications.

Yeti's checklist for Virtual Box may help sort it out also.

You have your computers hidden so we can't look at your setup and see things like how much memory you have, number of cores and software versions.
Can you post some of you info? Are you running any other BOINC projects or just LHC? What work units are you running at LHC? Are your preferences default or did you change them?

You can also try looking at Yeti's Checklist in Number Crunching.

You mention upgrading your processors. How old were your motherboards and what speed RAM is supported. You may see a slight performance upgrade depending on your memory speeds. Have you taken a look at that?

I guess, just turn off Atlas for a few days. Maybe something is messed up and it has to wait until it gets looked at early next week. Are the other tasks running okay for you? It is just Atlas being a problem?

I am not familiar with how Virtual Box uses memory but I don't think it can page it out on the Host OS and requires real ram. Have you worked through Yeti's checklist in the Number Crunching forum? I would try to get one VB related task going and opt out of the other in this project until you get it sorted out. You do need to leave enough memory for the OS. I have mine set to 75% in use and 90% idle with 16Gb installed. You might be able to run two concurrent, eight core Atlas tasks but it doesn't leave much room.

You seem to have memory related errors on a bunch of your recent Atlas tasks.

Are you running low on memory in Host OS or are you hitting a memory limit in your Preferences?
