This system does not use Partition Firmware.  KVM uses SLOF.

The error is a Program Exception 700, which is an illegal instruction.  The 
address of the instruction in SRR0 is 0.  Code is attempting to execute at that
address.

That exception is caused by a VSX exception (f40 at SRR0) in the release
13 of grub package. A new package (14) was released friday and fixes
that problem.

grub is fixed in the ISO but in order to use this new version another
package, debian-installer, needed to be rebuilt.

SO it looks like some patches were not forward-ported to grub-installer
in 15.10

FYI: Another dup was LTC bug 116767, which was mirrored to LP 1375216.
