RN31200 - Installing virtualbox on ReadyNas 6.5.0

[enxer]

I just recently purchased a 312 and I've been following JMehring's post: https://community.netgear.com/t5/Community-Add-ons/Virtualbox-on-OS6-NAS/td-p/902756 and I get stuck on installing virtualbox (I am using the newest from virtualbox.org ( virtualbox-5.1_5.1.0-108711~Debian~wheezy_amd64.deb):

# Get the latest from virtualbox.org (debian build)
dpkg -i virtualbox-4.3_4.3.4-91027~Debian~wheezy_amd64.deb

/etc/init.d/vboxdrv setup

modprobe vboxdrv
modinfo misc/vboxdrv.ko

This is what the installer throws:

root@NAS:/data/Virtualbox# /sbin/vboxconfig
/sbin/modprobe: invalid option -- 'c'
BusyBox v1.22.1 (Debian 1:1.22.0-4) multi-call binary.

Usage: modprobe [-alrqvsDb] MODULE [symbol=value]...

        -a      Load multiple MODULEs
        -l      List (MODULE is a pattern)
        -r      Remove MODULE (stacks) or do autoclean
        -q      Quiet
        -v      Verbose
        -s      Log to syslog
        -D      Show dependencies
        -b      Apply blacklist to module names too

vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.

There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

I get the modprobe error (this modprobe has no config dump option) but -failed to install vboxdrv? oh Really? - running modprobe -l I get this (all the complied kernel modules I built earlier):

dmesg complains:

My srcs (both link to /data/Virtualbox/linux-4.1.21-197-x86_64 folder):

root@NAS:/data/Virtualbox# ls  /usr/src/
linux  linux-4.1.21-197-x86_64  vboxhost-5.1.0

and my uname info:

root@NAS:/data/Virtualbox# uname -r
4.1.21.x86_64.1
root@NAS:/data/Virtualbox# uname -a
Linux NAS 4.1.21.x86_64.1 #1 SMP Wed Jun 1 16:52:57 PDT 2016 x86_64 GNU/Linux

How can I get /sbin/vboxconfig to complete successfully?

Sorry for not getting back to you until now - I saw your post but two active kids kept me busy from repling to these threads I've made.

So I posted over in virtualbox and they reiterrated that my headers I built were not matching the running ones dispite the uname -r matching so I scraped everything, purged all modules and /usr/src and reviewed the orginal url  that this author got. I pulled a similar name down that matched my readynas os 6.5.1 and made them. Additionally I added the debian repository for virtualbox wheezy and I installed dkms which monitors for kernel header changes and compiles based on the kernel modules in the system. This got me to be able to install 4.3.8 which is happily running my Windows 7 32bit (I have atom processor (non-VT-x)) running Passwordstate for the house quite well.

I hope my post helps someone out!

Hello enxer,

I suggest you contact the developer of this app you are trying to install. This is not listed and was not submitted to Netgear yet.

Welcome to the community!

Trying the same thing here, and also having issues with module magics, though it's possibly something else I'm doing wrong.

Out of interest, you've mentioned directory showing some additional number in it (197):

linux-4.1.21-197-x86_64

The kernel dir I have out of the latest zip here:

http://www.downloads.netgear.com/files/GPL/ReadyNASOS_V6.5.1_WW_src.zip

just has a directory called:

linux-4.1.21-x86_64

With this kernel:

head -4 /usr/src/linux/Makefile
 VERSION = 4
PATCHLEVEL = 1
SUBLEVEL = 21
EXTRAVERSION =
NAME = Series 4800

Where'd you get the kernel sources with this extra number in the directory name?

As for my lack of success, I'm not even able to

sudo cp .config .config-old
sudo cp arch/x86/configs/defconfig.x86 .config
sudo make clean
sudo make ARCH=x86_64
sudo make modules_install ARCH=x86_64

then 

sudo modprobe configs
# modprobe: can't load module configs (kernel/kernel/configs.ko): invalid module format

So I'm expecting anything the VirtualBox installer is trying to build will fail with mismatches also.

sudo modinfo configs
vermagic:       4.1.21.x86_64.1 SMP mod_unload modversions
 
uname -r
4.1.21.x86_64.1

Seems... Odd to me.

ReadyNAS 6.5.1

Actually sorted this out in the end.

On a hunch I'd got the wrong config, I had a look around and realised there's a special config file for the readynas setup...

#Normal
#sudo cp arch/x86/configs/defconfig.x86 .config
#ReadyNAS
sudo cp arch/x86/configs/readynas_defconfig .config

Give this a shot and see if it works.  You may need to do a clean out first (of /lib/modules & kernel build dir).

Have written up a full description based on a number of great forum posts.
