[gentoo-user] Re: GUI-less (non-dbus) virt-manager (to run Tails in Gentoo)

[Miroslav Rovis]

This email will be about some good results that I have obtained in this
non-dbus virt-manager matter, and at least one snag left to solve...

I have made a lot of progress in using non-dbus virt-manager recently.

I hope some readers might be interested in these not very usual, except
in Gentoo, feats.

Let me remind you:

The above is still the case. And so is the below.

This is what I thought that I needed to do at the onset:

But there is now the better debian than the systemDestructed Debian,
which is Devuan, and there is now Heads (based on Devuan) instead of
Tails (based on Debian):

https://heads.dyne.org/about.html
or
http://fz474h2o46o2u7xj.onion/about.html

And, as far as Tails, I can use it, although as of this time still only
in pure Qemu (just a little is still missing for full Libvirt deployment
under sound control of grsecurity RBAC policies... more below about
that):
https://www.croatiafidelis.hr/foss/cap/cap-161015-qemu-devuan/qemu-devuan-10.php
(and the successive page)

This was wrong, that's for developers

But I first need to complete setting up the grsecurity RBAC policies for
Libvirt:

Libvirt virtualization policies
https://forums.grsecurity.net/viewtopic.php?f=5&t=4675

which I might be at an end of (that took time! but it feels
rewarding)...

All of that I have successfully managed to do without dbus...

Or d-bus, like in the comparison table of init systems:

https://wiki.gentoo.org/wiki/Comparison_of_init_systems

Which I hope is slowly spreading from Gentoo into other true-unix FOSS,
the sans-dbus OpenRC...

But I would need time to see, say, how far Devuan has reached in
implementing OpenRC, as they planned...

(I'm not a dev, I'm only yet struggling to become a good
tester for projects that I believe in...)

I have also hit a snag... see the last post at:

Whonix on Gentoo issues
https://forums.whonix.org/t/whonix-on-gentoo-issues/3188/17
where find (pasting:

(virt-viewer:9916): GSpice-CRITICAL **: egl init failed: cannot create
EGL context

and more. That's basically, my virt-manager, virt-viewer and spice, and
spice-gtk and xf86-video-qxl have some issues, and when virt-viewer
starts, the spice client can't get the egl context, which I have come to
understand is the... keyboard and the mouse...

In slow time, if anybody has any advice about this matter, I'll be
greatful!
