Running VirtualBox VM host on ReadyNAS Pro
What is VirtualBox?
So, I got bored while laundry was going... and decided to see how well a virtual OS would run on the Pro. My first choice of VM was VirtualBox, just cause I'm familiar with it after using it for ages, plus its open and free :) Eventually, I may look into VMWare as well.
After a bit of messing around, got it installed. Since the system is based off of Debian, was easy to get VirtualBox itself there (deb package). The trickiest part was getting the kernel modules required installed (see end of post).
In the end, I've got Windows 2003 R2 running on my Pro, interacting with it via RDP, and I am happy with the performance. I've added an extra 1GB memory (for a total of 2GB). I assigned 1GB of ram to my virtual OS, which still leaves the default configuration of 1GB for the NAS itself (which is more than enough still, 800MB+ is always cached).
I made a 10GB virtual disk to install the OS on. If I need more space later for extra applications, I can just add another virtual drive to that installation. And since I always like a bit extra security, I went a bit beyond the usual, and also have TrueCrypt running full disk encryption in the virtual OS. So no one can even boot and read the data in that OS without my bootup password.
I don't really have any screenshots to show, just a standard Windows installation. Here is a few of the steps I used while creating the VM on the console:
VirtualBox 3.1 has changed the CLI configuration. Until I update this how-to, please reference this: http://www.uhleeka.com/blog/2009/12/vir ... 9-04-host/
With the OS booted up and just sitting at the desktop, top reports:
Ad-hoc installation of VirtualBox. Should work for RAIDiator 4.2.4. Download links for the kernel modules, for those who don't want to go through the mess of compiling them.

- for some reason the vboxdrv.ko file disappears all the time..
anyway i got a little further:ReadyNAS-Pro:/lib/modules/2.6.27.6.RNx86.2.1/misc# /etc/init.d/vboxdrv start

VBoxHeadless: Tip! Make sure the kernel module is loaded. It may also help to reinstall VirtualBox.
hmmm :(beisser wrote: 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.
-Dave- that did it :) thanx
now installing server 2003 just for fun.. - the insmod-stuff was nmentioned nowhere in chirpas text.. that was the missing link.
- My bad, missed a step in my ad-hoc installation ;) Like I said, it was not tested. This will do the same thing as the insmod steps:
/etc/init.d/vboxdrv start
Haven't rebooted yet to see if that runs on bootup properly. - do you know if there's a php interface or so we can add in a add-on ?
- PHP interface to VirtualBox?
chirpa wrote: PHP interface to VirtualBox?
that would actually rock.. an interface where you can easily create new vms, new disks or modify existing ones.- I do a quick test :
if we want an add-on will all the deb files in it , the size will be 59 MB :(
