Operating Systems Solaris Virtual Terminal (Console) showing non-global zone? Post 303037503 by LonnieTC on Saturday 3rd of August 2019 09:47:30 AM

Hello Hicksd8,

Thanks so much for your reply and let me give a little more information as I am a bit new to the Unix (Solaris 11 based) side of things while coming from the Linux world.

The version that I am using is actually SmartOS which is Illumos-based and I think that it is closest to Solaris 11 from the OpenSolaris branch, if my reading has been correct, but could be wrong on this.

So then, what I am thinking is this. When I boot, the result is that the system starts up and I have a physical console (wscons) that I can login to which is the Global Zone, from what I understand. From there, if I hist <Alt>+<F2>, then I get the "vt2" screen which will also allow me to login. Of course, it looks to be configured all of the way to "vt6" via <Alt>+<F6>. I have seen in the source code where this is setup so I now have a basic idea on the virtual terminals.

I am also figuring out the zone system which is similar to "jails", "sandboxes", or "chroot" in Linux and other systems so that they are basically configurable virtual machines akin to Docker containers which can also be configured as assigning physical devices to them from what I have read in the Solaris 11 world with "zonecfg".

I do not want to run many things in the global zone, so what I am attempting to figure out, if it is possible, is to have the Global Zone on, say "vt2" and have a Non-Global Zone on "wscons" since I want to have an xserver running in the non-global zone such that the xserver does not need to be added to the global zone. This way, the xserver and x11 application is in the non-global zone and comes up at boot time, and to access the global zone, I can use <Alt>+<F2>, for example and then login to it as needed.

Basically, the user interfaces via "wscons" console and admin stuff is in the global zone on "vt2", for example.

Something like this is what I was actually thinking.
Thanks

NAME

       zcons - Zone console device driver

DESCRIPTION

       The  zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
       tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the  global
       zones.

       Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave  side is fronted
       by /dev/console and other console-related  symbolic links, which are used by applications that expect to write to the system console.

       The zcons driver is Sun Private, and may change in future releases.

FILES

       /dev/zcons/<zonename>/masterconsole

	   Global zone master side console for zone <zonename>.

       /dev/zcons/<zonename>/slaveconsole

	   Global zone slave side console for zone <zonename>.

       /dev/zconsole

	   Non-global zone console (slave side).
