Cambios en las certificaciones de VMware VCP

En espera de los nuevo cursos para poder certificarse: VCP pasara a llamarse VCP-DV, si ademas realizamos el examen VCP-IaaS, nos servira de puente para la certificación definitiva y que se presupone como única en un futuro: VCP-Cloud

VCP: VMware Certified Professional
VCP-DV: VMware Certified Professional - Datancenter Virtualization
VCP-IaaS: VMware Certified Professional - Infrastructure as a Service
"VCP-IaaS does not include datacenter virtualization topics, while VCP-Cloud will include both datacenter virtualization & infrastructure as a service topics."

La info del enlace oficial (http://mylearn.vmware.com/mgrReg/plan.cfm?plan=32558&ui=www_cert):


Become a VCP-Cloud

There are two paths to earning your VCP-Cloud certification.
Path 1
  1. Be a VMware Certified Professional 5 – Datacenter Virtualization (VCP5-DV)
  2. Pass the VCP-IaaS exam  
    "VCP-IaaS does not include datacenter virtualization topics, while VCP-Cloud will include both datacenter virtualization & infrastructure as a service topics."
Path 2
  1. Attend a qualifying course
  2. Pass the VCP-Cloud exam – coming soon

vMotion sin datastores compartidos? Si con vSphere 5.1

Una de las nuevas funcionalidades de la versión VMware vSphere 5.1 es la posibilidad de mover maquinas en caliente sin la necesidad de tener un datastore compartido entre los dos host ESXi.
Únicamente esta restringido para host del mismo Datacenter dentro de un mismo vCenter... alguna pega tenia que tener.... o quizas se quieran dejar algo para la version 6 ???

Asignar un RDM desde FreeNAS 8 a una maquina virtual en vSphere 5

   Vaya por delante "RDM: Raw Data Mapping" y visitad este enlace para mas info:



     Para asignar un disco RDM a una maquina virtual directamente desde nuestra SAN o NAS sin crear un .vmdk, debemos primero crear un volumen en nuestra cabina y luego presentarselo por iSCSI a los host ESXi. A continuacion se lo agregamos a la maquina virtual desde las settings y ya dentro del S.O. de la mv agregamos el disco como si de una nueva unidad se tratase.

#VMware vMA 5 ip pool error when power on at first time

If you deploy the VMware vMA 5, after power-on for the first time, you will get (or not) en error about an ip pool configuration is needed to start the virtual machine. The solution is quiet simple, edit settings of this vm and  disable the vApp options on the Options tab, save changes and porwer on.

@Veeam: Replica mapping over WAN para #VMware

Una de las nuevas funcionalidades del Veeam 6 es la posibilidad de lanzar una replica contra una mv destino, lo que Veeam ha llamado como podeis ver en la imagen "Replica mapping".

Esto es muy util para replicar sobre WAN, ya que podemos realizar un full backup de una serie de maquinas del vCenter origen, transportarlas hasta su destino, restaurarlas en el vCenter destino y despues lanzar una "replica" over wan contra las mv´s restauradas, con lo que solo se transmiten por red wan los incrementales.

Otra opcion es utilizar al opcion de "initial seeding" que utilizara un repositorio donde tengamos un backup de las mv´s origen para lanzar la primera replica y no transferir por red el full de la mv. Basicamente Veeam creara automaticamente un restore de la mv desde el repositorio (lo que en el ejemplo anterior realizamos nosotros manualmente) y despues aplica los incrementales sobre la mv restaurada.

Como hacer backup de VMware ESXi con vicfg-cfgbackup

Para hacer backup de un host ESXi por consola, utilizaremos vicfg-cfgbackup y tambien nos servira para restaurarlo posteriormente.


Opciones del comando:




conn_options
Specifies the target server and authentication information if required. Run vicfg-cfgbackup --help for a list of all connection options.

--force | -f
Forces the restore of the configuration.

--help
Prints a help message for each command-specific and each connection option. Calling the script with no arguments or with --help has the same effect.

--load | -l
Restores configuration from onto the host.

--save | -s
Backs up the host configuration.
Include the number of the build that is running on the host that you are backing up in the backup filename. If you are running the vSphere CLI from vMA, the backup file is saved locally on vMA. Local storage for backup files is safe because vMA is stored in the /vmfs/volumes/ directory, which is separate from the ESXi image and configuration files.

--reset | -r
Resets the host to factory settings.

--quiet | -q
Performs all operations without prompting for confirmation.






Ejemplos:

Backup del host a un fichero en C:\backup.txt:
 vicfg-cfgbackup  -s C:\backup.txt

Reset del host, restaurar opciones por defecto (restore factory settings):
 vicfg-cfgbackup  -r

Restaurar una configuracion anteriormente salvada en C:\backup.txt
 vicfg-cfgbackup  -l C:\backup.txt

Restaurar la configuracion desde C:\backup.txt sin preguntar confirmacion al usuario:
 vicfg-cfgbackup  -l C:\backup.txt -q

Nuevo #VMware #vCenter Operations 5.0

#VMware #vSphere #PowerCLI: consultar si las VM sincronizan con el host #ESXi (Synchronize guest time with host)


Para consultar si las VM de nuestro vCenter o Host tienen el check marcado para sincronicen la hora con el propio host donde esten inventariadas, podemos consultarlo en modo grafico a traves de las propias tools de la mv, o desde las settings de la VM (Synchronize guest time with host)


Pero cuando tenemos muchas mv´s, el mejor modo es realizarlo es mediante PowerCLI y estos sencillos scripts:

Con este listas las VM que No tiene el check marcado para sincronizar con el host:

get-vm |where { ( %{ get-view $_.Id } | where { $_.Config.Tools.SyncTimeWithHost -ne "True" } ) } | select name


Con este otro listas lasVM que SI tienen el check marcado para sincronizar con el host:

get-vm |where { ( %{ get-view $_.Id } | where { $_.Config.Tools.SyncTimeWithHost } ) } | select name

Solucionar Error 25085 al instalar #VMware vCenter Update Manager 5


Al instalar en vSphere 5 el Update Manager nos podemos encontrar con el "Error 25085: Setup failed to register VMware vCenter Update Manager extension to VMware vCenter Server".
Tras visitar varios blogs y KB oficiales.... con resultados mas bien nulos.... la solucion ha sido tan sencilla como poner en la instalacion la IP del vCenter donde queremos registrarlo en vez del nombre FQDN.
