Attaching to the virtual console/keyboard/mouse of kvm instance using a unix/socket

Attaching to the virtual console/keyboard/mouse of kvm instance using a unix/socket

[Thomas Glanzmann]

Hello,
is it possible to connect to the virtual monitor/keyboard/mouse of
an already running kvm instance using a socket when started without an
x-window system and _not_ using vnc? I have something in the back of my
head using libvirt but I am unable to find it.

Well -- if you're not doing anything graphical, you could use the new 
ncurses display mode. Set your scripts up to allocate a new PTY each 
time, connect those PTYs to screen, and you're golden. If your needs are 
simpler, something similar could be done using serial console support.

While libvirt doesn't currently know anything about serial console 
configuration or ncurses display / PTY support, it's just waiting on 
someone with time to implement it -- might eventually be me, if nobody 
else gets there first.
