Running VirtualBox VM host on ReadyNAS Pro

for some reason the vboxdrv.ko file disappears all the time..

It happened to me too.

I redownloaded the .ko files and inserted them into the kernel (you need to insert vboxdrv.ko before vboxnetflt.ko):

insmod vboxdrv.ko
insmod vboxnetflt.ko

I also updated to Raidiator T43 (you can probably just upgrade to 4.2.4 now that it's been released).

If you look very carefully, you can see in my screenshot above that there is an error message:

WARNING: The compilation of the vboxdrv.ko module failed during the installation for some reason.  Starting a VM will not be possible.  Please consult the User Manual for build instructions.

Obviously, we can see the VM is actually running, so I don't quite know what to make of the error.

The screen shots show a "Live CD" of Ubuntu 8.10 (everything working, albeit a bit sluggish --- only 1 GB RAM on the Pro). I also did not install the VBoxGuestAdditions_2.1.0.iso yet. Next, I performed the actual HD install of Ubuntu --- again, everything worked as expected.

I'll check my notes at home tonight to see if I've neglected to add any other pertinent details.
