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

[Miroslav Rovis]

I made it!

See:
http://www.croatiafidelis.hr/foss/cap/cap-170113_tails/
or open:
$ <your-browser> \
http://www.croatiafidelis.hr/foss/cap/cap-170113_tails/Screen_170113_2102_g0n_1.webm

(and also Screen_170113_2102_g0n_2.webm and Screen_170113_2102_g0n_3.webm )

But there are stories to tell, along with patches to share, and a place
for a nice bug report, coming.

( only when it's short info, and clear from the title what it's about,
do I top post )
