It might be caused by the fact that Leap uses SLE12 as a base for

bingo! adding

now, after boot, net's up

Immediately after boot, I can ping outbound.
I can't SSH *to* the machine -- sshd's not starting on boot. I *can*
restart it after boot, and subsequently SSH in. WIll chase that down
... suspect some changed dependency ....
So, appears there IS this default-value change from OS 13.2 -> Leap. If
that's the case, I can't imagine that this won't crop up for others, and
netnaming became standard with OS 13.2, and some netconfigs no doubt
addressed those names.
Is the need for the command-line parameter addition/change documented?
Since Leap now tracks SLES, will the default stay @ netnames = 0,
requiring a spec'n on command line?
Should that setting be taken instead from, e.g., /etc/default/* or
/etc/sysconfig/* ?
Curious, what's TW's default value? Same as 13.2 or same as Leap? Did
*it* change as well?
Again, it worked absolutely fine prior to the upgrade; the script executed,
and the knobs' values were verified to be set.
Likely by ifup scripts instead of wicked.
What is the wicked-native alternative?
That preceding "(null):" is a problem, but iirc is due to the lack of
properly init'd xenstored
wicked and xenstored are unrelated.
Sure.
Still now, after boot
xl list

which leaves me with "why?"

Which one was missing? xencommons.service is supposed to start them all.
Prior to my 'enables', I'd only checked
systemctl list-unit-files

Also found & removed these from the /etc/default/grub
- GRUB_CMDLINE_LINUX_XEN_REPLACE=" (.*) rdloaddriver=xennet
rdloaddriver=xenblk"
+ GRUB_CMDLINE_LINUX_XEN_REPLACE=" (.*) "
This is unrelated I think.
I'm not finding recent docs on rdloaddriver= usage, particularly wrt
=xennet, =xenblk. Something clearly set those ...
Now I've a booted system, with networking, I note on reboot a Xen+EFI
failure:
shutdown -r now
