Thirteen test files this branch adds call BAIL_OUT at fifty-one places:
an extraction that stopped matching, a fixture that is not there, a
harness that wrote no log. prove stops every remaining file on a
bail-out, not only the file that called it, so one of them hides the
results of every test that would have run after it. die is just as loud
and costs only its own file.
Fifteen comments the branch added also carried the incident rather than
the constraint. Three pasted an error transcript, five traced a failure
from a macro or a missing file out to a node that never boots, and the
rest counted call sites, package sizes or dracut build numbers. Each now
states the one fact the reader cannot re-derive from the code.

A node whose vmstorage is a libvirt storage pool (dir://, nfs:// or lvm://) got a <disk>
element with no bus attribute. libvirt then chose the controller from the name of the
device alone, so the disk of a riscv64 node worked only while its volume was named sd*.
build_diskstruct in xCAT-server/lib/xcat/plugins/kvm.pm matched the pool entry, a hash
reference, against /^vd/, /^hd/ and /^sd/. A reference in a match is its address as a
string, so no branch ran and the bus was never set. The name of the device is in the
device field of that entry.
The three tests now read that field. The bus each one sets is the bus libvirt gives an
hd*, sd* or vd* name, so no domain changes: a riscv64 node keeps the sd* name its volume
has, and keeps the scsi controller the riscv64 virt machine provides. libvirt stores the
domain built before this change with bus="scsi" on that disk, which is what the domain
built after it states.
kvm_diskstruct_bus.t drives build_diskstruct in a scratch package, with a stub storage
pool in place of the one routine that reaches libvirt, and asserts the bus of an hd*, an
sd* and a vd* volume. It also asserts that a riscv64 node keeps the sd* name of its
volume. Four of its seven assertions fail without this change.
