Bug Description

Calling iscsi ibft a 'virtual' thing is a bit questionable.

That said, I was looking at ibft using qemu and ipxe. The cloud images do not have the iscsi_ibft module included, so you can't read the information out of /sys/firmware/ibft until you have it.

Given a iscsi target at 192.168.1.131::3260:1:mytest (format is described at http://etherboot.org/wiki/sanboot/iscsi_boot) with a cloud image populated (or other bootable data) you can boot from that via:

qemu-system-x86_64 -enable-kvm -m 1024 -curses \
   -kernel /usr/lib/ipxe/ipxe.lkrn -append 'dhcp && sanboot iscsi:192.168.1.131::3260:1:mytest'

The ipxe.lkrn file is in the 'ipxe' package, and tested above on wily.

If the open-iscsi package is installed in the image and the modules available, in the initramfs you can then do:

(initramfs) modprobe iscsi_ibft
[ 11.444414] iBFT detected.
(initramfs) cat /sys/firmware/ibft/target0/nic-assoc
0
(initramfs) cat /sys/firmware/ibft/target0/target-name
mytest
(initramfs) cat /sys/firmware/ibft/target0/port
3260
(initramfs) cat /sys/firmware/ibft/ethernet0/mac
52:54:00:12:34:56
(initramfs) for x in /sys/class/net/*/address; do echo $x; cat $x; done
/sys/class/net/eth0/address
52:54:00:12:34:56
/sys/class/net/lo/address
00:00:00:00:00:00

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-wily' to 'verification-done-wily'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
