I recieved a new test machine on Friday, and being too lazy to set any particular tests running on it to burn it in I decided to just leave it running over the weekend creating as many zones as it could. Today I came in to discover that only 255 zones were created. The error message on booting the 256th was
bash-3.00# zoneadm -z rodent-z256 boot zoneadm: zone 'rodent-z256': eri0: could not add interface: No buffer space available zoneadm: zone 'rodent-z256': call to zoneadmd failedSure enough, trying to bring up another virtual interface on eri0 resulted in
bash-3.00# ifconfig eri0:256 plumb ifconfig: plumb: SIOCLIFADDIF: eri0:256: No buffer space available bash-3.00#To allow more interfaces you need to tweak /dev/ip ip_addrs_per_if. E.g. ndd -set /dev/ip ip_addrs_per_if 8192 . The new value takes effect immediately. The only place I can see this mentioned in the docs is in the script to configure multiple zones, but I wasn't using that script.

Thanks albert, that was some useful info.. i was breaking my head over why the agent simulator tool was not creating the virtual IPs.
