Page 201 Container Admin Guide on docs.sun.com states :
"The upper limit for the number of zones on a system is 8192. The number of zones that can be effectively hosted on a single system is determined by the total resource requirements of the application software running in all of the zones."

Please note that you may need to tweak the ip_addrs_per_if tunable in /etc/system 'cos the default number of logical interface per real interface is 256.

I just have a simple question.
What is the maximum number of local zone can I have?


I thought that it was around 8000, but zone.h seems to indicate that
MAX_ZONEID is 9999.  You will have to do other tuning to get to that
large of a number.  John Clingan http://blogs.sun.com/jclingan/ has
experimented with this and has achieved hundreds of zones with rather
modest[1] hardware.

You will tend to run into other practical limits for long term
maintenance (e.g. time to patch said system) before you run into
problems with the system running a large number of zones.


[1] This assumes that you buy into the idea that a 4 processor system
with 8GB of RAM is modest - I may be a bit spoiled.
