"Virtual Terminal (Console) showing non-global zone?"

Post #303037492 by hicksd8 on Saturday 3rd of August 2019 05:23:42 AM

Which version of Illumos are you talking? I guess it's the equivalent of Solaris 10 or Solaris 11?

Why are you trying to do this?

A zone can be configured to boot automatically when the global boots (set when the zone is configured). So you can stop the zone booting automatically and start it manually using zoneadm.

A connection to the zone virtual console will persist across zone reboots.

Are you trying to debug something? Looking for an error message?

When you boot a zone manually (zoneadm) it will return to a prompt long before the zone is actually 'ready'. You can use truss to provide more feedback if the zone crashes on boot:

Code:
 # truss -o /var/tmp/zoneadm.out -aef -vall -wall zoneadm -z <zone name> boot

You can then view the /var/tmp/zoneadm.out file to see if it tells you anything.

Reference material from Oracle:
Non-Global Zone Login Methods - Oracle Solaris Administration: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management

More information please. The skillset on this forum is awesome and I'm sure somebody here will help once we know what you are trying to achieve.

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). ATTRIBUTES
