1) Message boards : Number crunching : VirtualBox needed?
Message 46156
Posted 3 Feb 2022 by OliverF 		Hi all,
I am running two Linux boxes (Gentoo) and since recent they seemed fairly happy to pull native tasks. Lately I get the message in the log that VirtualBox would not be installled (LHC and Rosetta by the way)
I installed VirtualBox, VBoxManager starts up fine, boinc user added to the vboxusers group. Alas, I still get that error message.
How does BOINC decide if it thinkx vbox is there or not? Where can I find more detailed logs to check and troubleshoot that?

Any help much appreciated.

Thanks,
Oliver

That is a great checklist, just what I was looking for....

I got stuck already on the VT-X check, but I have contacted the developers of the tool already. VT-X is enabled in BIOS and running a Xeon E5 2620v4 I would tend to think I get two green checks, but I don't.
Should I get any updates, I'll let you know here.

The BOINC installer I believe also checked that, I seem to recall that I got two messages in the process that virtualization was a) supported and b) enabled.

Of course I still read through the rest of your checklist, now I have one, quite general, question....

Does it make sense to try all that on a box with 8Gig of RAM?

It feels as if it is generally quite fruitless to try with that amout of RAM, specifically if you try running other projects/stuff on the box as well.
I have a Windows Home Server 2011 OS on the box, and though that is based on Server 2008 R2, it comes with a - quite annoying - 8Gig RAM limitation.

Best Regards,
Oliver
