On Ralph@Home project i'm trying to download some VirtualBox wus, but i receive this error:

VirtualBox jobs require hardware acceleration support. Your processor does not support the required instruction set.

I wrote in their forum, but i know that they do not read, so i write here.

- I have a Ryzen5 5500U, that supports virtualization.
- I see "virtualization enabled" in cpu properties (Task Manager\Performance tab).
- I run correctly some VMs in my VirtualBox (for some testing purpose).
- I have no MS Hyper-V installed

It's a boinc server problem?

I think it is a bios setting. I am struggling to remember what it is. There was one I had to tick that was obvious to get LHC tasks to run. Something else I wanted needed me to find something more obscure setting which was different from what the error message told me was different. (I think the error message told me what it was for an Intel chipset whereas my MB and CPU are AMD. I eventually found it after googling the equivalent for AMD.

Edit: Just signed up but currently no tasks ready to send so can't tell what will happen with my box.

OK, 4.3GB vdi now downloading. Will be back from work around six to see if it is running or not. On bored band, it will take a while to download!

I think it is a bios setting.

No. Bios settings is ok, virtualization enabled

- I have no MS Hyper-V installed

Maybe, after some hours of work, i find the solution (and, maybe, this help others with the same problem).

I installed MS Hyper-V over 1 year ago (for some tests) and, at the end, i removed it from control panel/programs and features/turn windows feature on or off.
Today, using command

systeminfo

from PS, i see the message "A hypervisor has been detected. Features required for Hyper-V will not be displayed"
That's stange!
So i used the command

Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor

Nothing to do, still the same error.
I disabled Secure Boot from bios, restart the pc and re-used the command above and also another command

DISM /Online /Disable-Feature:Microsoft-Hyper-V

I restarted again the pc and the message in boinc manager has gone.

Waiting for work to see if it's solved (maybe i'll try with lhc@home)

OK task is running. My host machine is Ubuntu so anything I have done to get it everything working may not be relevant.

And at 46% complete, the task says, Postponed:VM job unmanageable, restarting later.

Have posted on Ralph@home asking how I can encourage the task to restart.

The task will automatically restart after the end of the 86400 s break.
It will also restart after a BOINC client restart (if no other task has a higher priority).


Ralph uses vboxwrapper 26202, right?
That (Windows-)version is built against Microsoft's .com interface which is known to occasionally show the postpone issue.

Recent vboxwrapper versions do not use the .com interface any more.
Hence, the project developers should be asked to use the most recent vboxwrapper (currently 26206):

Have posted on Ralph@home asking how I can encourage the task to restart.

Restarting client appeared to get the task to complete successfully, at least according to the task page. However it went in a couple of minutes or less from 46 to 100%.
