Install 11.4 kernel zone with proxy

Hi folks,

How can i install a kernel zone behind a proxy?

Using the proxy in the publisher (works for global and non kernel zones) leads to:

PUBLISHER                  TYPE    STATUS P LOCATION

solaris                    Quelle  online T https://pkg.oracle.com/solaris/support/

# zoneadm -z kliczone install

ERROR: publisher solaris: proxy URI not supported for install

creating the publisher without proxy leads to timeout:

PUBLISHER                  TYPE    STATUS P LOCATION

solaris                     Quelle   online F https://pkg.oracle.com/solaris/support/

Framework error: code: E_OPERATION_TIMEOUTED (28) reason: Connection timed out after 60000 milliseconds
