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
