Running VirtualBox VM host on ReadyNAS Pro

Edit: It seems Netgear has made some mistake or I'm just tired... the new GPL source supplied contains kernel version 2.6.37.5.RNx86_64.2.2 but the kernel that's included in 4.2.16 is version 2.6.37.5.RNx86_64.2.1

I don't know how you come to that conclusion. The GPL sources I'm using contain a kernel that identifies itself as "2.6.37.5.RNx86_64.2.1" - as can be checked by

cd linux-2.6.37.5/arch/x86/configs
grep "RNx86" *

Should list defconfig.smp with a CONFIG_LOCALVERSION string of ".RNx86_64.2.1"

Netgear have not only provided us with a GPL source that doesn't match the one they used to build the actual 4.2.16 release but they also have an incomplete kernel source lacking patches needed to compile! Both drivers/target/target_core_iblock.c and drivers/target/target_core_pscsi.c and has references to an undecleard pointer, 'blkdev_get_by_path'

I just compiled the kernel for the fun of it. Those two files you name aren't built here at all so that has to be related to a problem with your kernel config. Also the kernel is built without problems for me.

I'm going to try and patch the source now but I fear I might break Frontview by replacing the firmware kernel by my own build.

No need to worry, you simply can't replace the kernel. The worst thing that'll happen is that your modules will fail to load.

So I think we're out of luck (to get VirtualBox back any easy way) until Netgear realizes their mistake and re-releases the GPL source they really did use when they built 4.2.16.

Well, I don't know who's to blame here and I'm not going to judge either. All I can say is that it works for me using the GPL source archive I downloaded. Which may be a different one than the one you downloaded but I don't know that either. I do know, however, that the md5sum of my GPL sources archive matches the MD5 given at the download page for 4.2.16 GPL sources.
