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

       lx - Linux branded zone

DESCRIPTION

       The  lx	brand  uses  the branded zones framework described in brands(5) to enable Linux binary applications to run unmodified on a machine
       with a Solaris Operating System kernel.

       The lx brand includes the tools necessary to install a CentOS 3.x or Red Hat Enterprise Linux 3.x distribution inside  a  non-global  zone.
       The  brand  supports  the  execution of 32-bit Linux applications on x86/x64 machines running the Solaris system in either 32-bit or 64-bit
       mode.

   Supported Linux Distributions
       The lx brand emulates the system call interfaces provided by the Linux 2.4.21 kernel, as modified by Red Hat in the RHEL 3.x distributions.
       This kernel provides the system call interfaces consumed by the glibc version 2.3.2 released by Red Hat.

       In addition, the lx brand partially emulates the Linux /dev and /proc interfaces.

   Configuration and Administration
       The  lx brand supports the whole root non-global zone model. All of the required linux packages are installed into the private file systems
       of the zone.

       The zonecfg(1M) utility is used to configure an lx branded zone. Once a branded zone has  been  installed,  that  zone's  brand	cannot	be
       changed	or removed. The zoneadm(1M) utility is used to report the zone's brand type and administer the zone. The zlogin(1) utility is used
       to log in to the zone.

   Application Support
       The lx zone only supports user-level Linux applications. You cannot use Linux device drivers, Linux kernel modules, or Linux  file  systems
       from inside an lx zone.

       You cannot add any non-standard Solaris devices to a Linux zone. Any attempt to do so will result in a zone that zonecfg(1M) will refuse to
       verify.

       You cannot run Solaris applications inside an lx zone. Solaris debugging tools such as DTrace (see dtrace(1M)) and mdb (see mdb(1)) can	be
       applied to Linux processes executing inside the zone, but the tools themselves must be running in the global zone. Any core files generated
       are produced in the Solaris format, and such files can only be debugged with Solaris tools.
