VBoxDrv: Too many CPUs (288) for the GIP (max 256) (#16999)

We are trying to install virtual box on a Hitachi server with 288 cores.
However, on using apt-get to install virtual box we get the following warning/errors:
Code: Select all
[6276452.873981] vboxdrv: module verification failed: signature and/or required key missing - tainting kernel
[6276452.882765] vboxdrv: Found 288 processor cores
[6276452.885176] VBoxDrv: Too many CPUs (288) for the GIP (max 256)
We are unable to proceed from here. Any help is appreciated.
Host OS : Ubuntu 16.04
Code: Select all
$ uname -a
Linux enigma 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04

Thanks in advance!
{edit: added host OS details}

I'm no Linux expert, but AFAIK if you are installing VirtualBox via "apt-get" then you aren't installing VirtualBox at all, you're installing a distro fork, and should ask support questions for it on the Ubuntu forums.

Well, from the downloads page, we followed the instructions to install from apt-get.
From what I understand, the check happens in the source file:
Code: Select all
vbox/src/VBox/HostDrivers/Support/SUPDrvGip.cpp
which means irrespective of the distribution of virtualbox, this is a limitation.
I am interested to know if there is a work around to overcome this limitation.

As you see the MAX amount of CPU cores supported is 256 and if you want this to work you would need to get the DEVs involved. They can be reached via IRC or their mailing list.

I could certainly fix this! Just ship me your system and I will provide the necessary patches.
PS. It *does* run OSX, right? That's the only thing I can compile on. For PowerPC of course...

On a serious note, from what I understand, there are issues with CPU scheduling when the number goes beyond 256 cores.
For now, we are stuck to the option of limiting the cores in the BIOS.
