Operating Systems Solaris A little complex: why my packet don't route? Post 303026129 by Peasant on Tuesday 20th of November 2018 02:07:22 PM

In global zone, a network interface (VNIC) is created on L2 (MAC layer), with unique MAC address.
That is created/assigned to a zone, during zone install/creation or can be done manually as you did in first example.

When using exclusive IP stack, global zone does nothing on IP layer (L3).
So you do not need or require those forwarding options on global zone, or anything really outside vnic definition for zone.

As for your original problem, i presume KVM virtual switch discards everything not coming from assigned interface MAC from options for solaris 11 guest.
For a lab enviroment you can probably a tcpdump or snoop on kvm hypervisor interface and global zone guest, then see if network works in non global zone when dumps are running.

Hope that helps

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).
