¿ Para qué instalar VMware ESXi sobre VMware Player?
Quizás …
… preparas una certificación de VSphere y necesitas un entorno de aprendizaje.
… eres sysadmin y quieres un entorno de pruebas.
… vas a realizar una actualización en breve de tu entorno VSphere 3.X/4.X y quieres conocer la nueva versión.
… por gusto.
El entorno usado para la instalación es un PC con las siguientes características:
CPU: AMD Phenom(tm) 9650 Quad-Core Processor
RAM: 8 GB DDR2 (800MHZ)
SO: Ubuntu 11.10 versión Desktop
Kernel: Linux nas 3.0.0-15-generic #26-Ubuntu SMP Fri Jan 20 17:23:00 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
El proceso de instalación es fácil a diferencia de versiones anteriores de VMware. Enumerándolas son las siguientes:
1. Descarga de VMware player en su versión 4.0.2
Enlace de descarga
2.Instalar VMware Player
Desde un terminal ejecutar instalador:
# ./VMware-Player-4.0.2-591240.x86_64.bundle
Por defecto, aceptas licencias y demás preguntas finalizando con la siguiente salida:
Extracting VMware Installer…done.
3.Descargar la iso de ESXi5
Enlace de descarga
Recordar que en la descarga se te proporcionará una licencia gratutita que necesitarás después de pasar el tiempo de pruebas (60 días).
4. Creación de la máquina virtual ESXi en VMware Player
Desde el menú de VMware Player utiliza la opción de crear nueva máquina virtual (Create New Virtual Machine). El wizard pedirá una serie de detalles de la configuración de la nueva máquina entre ellas destaco:
Instalación desde iso apuntando al fichero que nos hemos descargado en el punto 3, el tipo de Sistema Operativo "Other" que por defecto al leer la iso lo indentifica como "Custom (VMware ESXi 5)":
Una vez finalizada la creación de la máquina virtual, ántes de arrancarla, aconsejo ajustar la siguiente configuración Hardware (a título informativo):
CPU: 2 cores y activar la opción de virtualización.
RAM: +2GB
RED: Modo Bridge (para que coja la primera IP por DHCP)
Las "Best Practices" para parametrizar tu instalación la puedes encontrar aquí.
5. Instalador de ESXi
El primer arranque de la nueva máquina se hace desde CD ( iso en la máquina virtual) que cargará el instalador de ESXi. Se trata de un instalador interactivo que se completa en menos de 4 minutos … dejo a continuación unos pantallazos del proceso de instalación:
ESXi 5 Menú de arranque del instalador
ESXi 5 arranque de la instalación
ESXi 5 Confirmar la instalación
ESXi 5 Finalización de la intalación
Después del reinicio, al final del primer arranque, informará de la IP que tiene el nuevo Host creado con ESXi 5.
Para conectarse desde una máquina Windows puedes acceder a través de un navegador a la IP de la máquina virtual ESXi 5 y desde allí descargar el cliente de administración de VSphere e instalarlo …
Se me ocurren muchos usos con la virtualización para escritorio de un ESXi:
– Instalar un vcenter en una máquina virtual o física para gestionar un clúster de ESXi.
– Duplicar ésta máquina virtual, cambiándole la IP y el Hostname, según la posibilidades del equipo se podrían replicar varias veces.
– Usar un almacenamiento externo tipo iSCSI (físico o virtual) descrito en posts anteriores para convertirlo en un Datastore vmfs, con multipath, balanceo round robin, …. recordar que VMware certifica los targets de almacenamiento SCST.
– Todas las posibilidades para aprender en tu entorno de pruebas ….
