Doubt on non global zone dedicated-cpu usage ??

Hi All,

While creating zone we will mention min and max cpu cores, If the non global zone uses only minimum cores at particular time What the other cores will do?
Will it shared to global zone?

If we do prstat in non global zone is it show only the allocated cpu cores for that zone or it will show all the core including global zone?

NAME
zcons - Zone console device driver DESCRIPTION
The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica- tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global zones. Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave side is fronted by /dev/console and other console-related symbolic links, which are used by applications that expect to write to the system console. The zcons driver is Sun Private, and may change in future releases. FILES
/dev/zcons/<zonename>/masterconsole Global zone master side console for zone <zonename>. /dev/zcons/<zonename>/slaveconsole Global zone slave side console for zone <zonename>. /dev/zconsole Non-global zone console (slave side). ATTRIBUTES
