I don't know what the problem is, but this suggests it lies within
pygrub. Try running pygrub separately to see what happens, i.e.:

# /usr/lib/xen-4.4/bin/pygrub /dev/host-disk2-vg/guest-disk

pygrub copies the kernel and initramfs out of the guest disk to
somewhere else so it really might be running out of space somewhere
in the host. I forget where it writes it to though, it's been a
while.

Cheers,
Andy
