Haiku from real hardware to Virtualbox

Hi,
I’d like to clone my Haiku installation from a partition on my hard disk to a Virtual disk.

Since there is no USB support in Haiku with virtualbox, i’ve found a workaround: i made a raw image of Haiku partition and then i converted this raw image in a bootable iso (i can also use this iso to clone Haiku with my personal settings and personal data on my others PCs), and i’ve used this ISO as Bootable CDROM inside VirtualBox, but Haiku hang at the rocket icon. With “on screen debug” I can read these errors:

runtime_loader: /boot/system/bin/sh: Troubles reading ELF header
error starting "/bin/sh" error = -2147478782

And above i can read:

Could not load kernel add-on "/boot/system/add-ons/kernel/drivers/dev/disk/usb/usb/usb_disk": Not an executable
Could not load kernel add-on "/boot/system/add-ons/kernel/drivers/dev/disk/usb/usb/usb_floppy": Not an executable
Could not load kernel add-on "/boot/system/add-ons/kernel/drivers/dev/disk/virtual/nbd": Not an executable

But on VBox there is no USB device attached. But in any way… There’s a way to solve this boot issue?

Thanks in advance.
