Что имеем: последний выпуск Nevada и установленный на него пакет Brandz, позволяющий запускать внутри Solaris Zone операционные среды отличные от Solaris. Цель: запустить из-под Solaris какой-либо Linux-дистрибутив.
Пока к сожалению brandz поддерживает только дистрибутивы CentOS 3.0 - 3.7 и и другие Linux с ядром 2.4, потому попробуем поставить на нашу систему CentoS 3.7:
$ cd /home/test/CentOS
$ wget http://www.gtlib.gatech.edu/pub/centos/3.7/isos/i386/CentOS-3.7-i386-bin1of3.iso
$ wget http://www.gtlib.gatech.edu/pub/centos/3.7/isos/i386/CentOS-3.7-i386-bin2of3.iso
$ wget http://www.gtlib.gatech.edu/pub/centos/3.7/isos/i386/CentOS-3.7-i386-bin3of3.iso
Теперь создадим brandz-зону. Запускаем утилиту zonecfg с параметром -z, именем зоны и далее обозначаем некоторые дополнительные параметры конфигурации:
$ zonecfg -z centostest
centostest: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:centostest> create -t SUNWlx
zonecfg:centostest> add net
zonecfg:centostest:net> set physical=ni0
zonecfg:centostest:net> set address=192.168.1.25
zonecfg:centostest:net> end
zonecfg:centostest> set zonepath=/zones/centostest
zonecfg:centostest> set autoboot=true
zonecfg:centostest> verify
zonecfg:centostest> commit
zonecfg:centostest> exit
Это обычный пример конфигурации зоны с одним сетевым интерфейсом и поднимающейся автоматически при загрузке системы. Далее устанавливаем бинарники CentOS в зону. Для этого запускаем zoneadm с параметром install и указываем путь к скачанным образам:
$ zoneadm -z centostest install -v -d /home/test/CentOS
Verbose output mode enabled.
