[indiana-discuss] unable to create zones

[Free]

hello all,
i've installed os2008.11 on a server, and i'm unable to create zone:
henry at antigone:~$ pfexec zoneadm -z www install
A ZFS file system has been created for this zone.
   Authority: Using http://pkg.opensolaris.org/release/.
       Image: Preparing at /zones/www/root ...pkg: 0/1 catalogs 
successfully upd:
     Could not retrieve catalog from 'opensolaris.org'
URLError, reason: (8, 'node name or service name not known')
failed to create image
rm: Unable to remove directory /zones/www/root: Device busy
zoneadm: zone 'www': '/usr/bin/rm -rf' failed with exit code 2.
zoneadm: www: cleaning up zonepath failed: Empty document

the network is ok because i've upgraded without problem:
henry at antigone:~$ beadm list
