Comment 29 for bug 1439280

But that makes no sense. If you were changing

# While earlier versions could support NUMA reporting and
# NUMA placement, not until 1.2.7 was there the ability
# to pin guest nodes to host nodes, so mandate that. Without
# this the scheduler cannot make guaranteed decisions, as the
# guest placement may not match what was requested
MIN_LIBVIRT_NUMA_VERSION = (1, 2, 7)

I could see that helping but MIN_LIBVIRT_BLOCKCOMMIT_RELATIVE_VERSION ?
