Install Ubuntu to iSCSI target from USB drive

[nry]

Hi all

Trying to setup my XBMC as diskless with little success so far.

I first tried to hook the drive I wanted to install to then boot from the ISO image.

Code:

sanhook iscsi:10.0.5.10:::9:iqn.2013-05.co.xxx:media1xbmc
sanboot --no-describe --drive 0x81 http://10.0.5.10/ubuntu.iso

This simply results in BusyBox loading, which seems to suggest that the ISO may be corrupt?

Then figured the easiest thing to do would be to boot from the USB drive as I don't plan on installing this very often.

Plugged in USB, set BIOS to boot PXE first with the following script

Code:

sanhook --drive 0x81 iscsi:10.0.5.10:::9:iqn.2013-05.co.xxx:media1xbmc
sanboot --no-describe --drive 0x80

The installer loads but when I come to select the disk to install only my USB drive is there.
I have tried with 'keep-san 1' in my script with no luck here.

Could someone point me in the right direction?
Thanks
