I remember I did try, but couldn't get '-usbdevice tablet' to work. Otherwise, I mostly managed to get the mouse working in my tentatives: Devuan image in Qemu https://www.CroatiaFidelis.hr/foss/cap/cap-161015-qemu-devuan/ But I never managed to solve the networking, with stock Devuan in VM that is, in all my tries above! (BTW, I'm stealing time from urgent obligations that I have now, bear with me if I don't reply soon to further discussion.) Not with stock Devuan in VM, but yes, I did solve in with Refracta, I even posted on Refracta forums, from within Refracta in VM: http://refracta.freeforums.org/refractasnapshot-10-0-0-arrived-t615-20.html#p5885 Here's the screencast and the network trace of that which was, for me, a huge success story (I was so happy when I made it!): https://www.CroatiaFidelis.hr/foss/cap/cap-161015-qemu-devuan/#No5 I'm now regularly using Refracta as rescue CD, of course, not from VM. I boot it from USB stick, load it in RAM, and I clone my systems (because I build Gentoo, and will eventually install and build Devuan, in Air-Gapped, and clone my systems btwn two, one Air-Gapped, the other online, same-model-hardware machines: very secure!), and I do other stuff.

I do have a network bridge set up, like this: https://wiki.gentoo.org/index.php?title=Network_bridge&oldid=613162 ( that's with my updates, the references there to: https://wiki.gentoo.org/wiki/Netifrc/Brctl_Migration and other stuff, are correctly set, IMO. BTW the bridge and things can be set the new, better way, from sysfs, without brctl, in Devuan as well, can it? ) [I do have a network bridge set up] for that purpose, and it works with Refracta, but I don't know how to get stock Devuan to use it for networking. > > HTH, > > Joel > > > NETWORKING DOESN'T WORK > > ----------------------- > > This is usually discovered as an apt-get install or apt-get upgrade > > failure.

I'll bear it in mind when I need it in the future. Just, you're right, no Schmoog the Schmoogle, thanx a bunch for the world's top spying agency, friends of all the Stasi's of the world, who made all their moneys snitching on everybody! No way!
