Hello Anthony,
Perhaps you could try running with xend instead of the xl toolstack ?
Since you have also changed the hypervisor version to 4.1.1, i think you were
previously using xend instead of xl ?
So in theory it could also be a problem in the xl toolstack causing the extra
qemu processes when building the domain.
