Thanks for replying.
However, my attempts got bogged down at:
virt-install playing poorly with grsecurity-hardened
https://forums.grsecurity.net/viewtopic.php?f=3&t=4609
(maybe some of grsecurity users among you Devuan can tell why such poor
play of virt=install with a (heavily) grsecurity-hardened kernel?... The
grsecurity-hardened Devuan is what I plan to try and achieve also with
DEvuan once I finally install it... But read my apologies at the end of
this email...)
Notice there a link to Gentoo Bugzilla to see why I was trying to see if
virt-install could do for me:
=sys-kernel/hardened-sources-4.7.6: Kernel panic when starting KVM
guests
https://bugs.gentoo.org/show_bug.cgi?id=597554
It's likely a use-after-free condition, according to PaX Team:

Thank you!
While I think the conversion to turn a Devuan guest is very likely much
more complex than a regular install, none of it can I still attempt to
do yet...
This has cost me a lot of time, and I got nowhere.
I did have a much nicer try with Devuan-based Refracta which I was so
glad about:
Devuan image in Qemu

Thanks again, and;-) sorry I work so slow...!
Just so you know, grsecurity is included by default in the kernel 4.x of
ascii :)
Cheers,
Aitor.
