I've noticed that in my FreeBSD there is /dev/vboxdrv (not vboxdrv0)
driver..
Probably different kernel module versions.?

Why do you use 2 controllers? I'm almost sure you can plug the ISO file
to SATA controller
Have you tried booting the machine only with CD attached?

For me it works without any issues.
The thing is that I am using VirtualBox 4.2.4 (it works well on my
environment, under 9.1-PRERELEASE amd64).
I'd recommend you to upgrade to 4.2.4

Ok, that should be supporting virtualization well ;)
Let me know about the results.
