zonep2vchk

- check a global zone's configuration for physical to virtual migration into non-global zone

Thezonep2vchkutility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone.

The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive

zonep2vchkserves two functions. First, it can be used to report issues on the source which might prevent a successfulp2vmigration. Second, it can output a templatezonecfg, which can be used to assist in configuring the non-global zone target.

When run on Solaris 10, a target release ofS11can be specified, which will check forp2vinto a Solaris 10 Branded zone.
