Virtualization, Cloud, Management, UC, Windows Tools and Registry Tips

Ya son varias la veces, principalmente en entorno de Cluster de Hyper-V, dónde una máquina virtual empieza a aparecer dos veces en la consola de Virtual Machine Manager, una de ellas generalmente en estado “Missing”.

En cambio desde Hyper-V Manager no se detecta ningún comportamiento erróneo.

Ni los acciones de Reparar ni de Borrado lanzadas desde Virtual Machine Manager sobre la máquina en estado “Missing” finalizan con éxito, reportando principalmente dos tipos de error.

Error (2915):

Error (802):

Un procedimiento que hasta el momento siempre me ha funcionado es atacar a la BBDD de Virtual Machine Manager con un script de Base de Datos ejecutado desde la herramienta Microsoft SQL Server Management Studio Express.

Antes de ejecutar el Script tendremos que parar el servicio de Virtual Machine Manager en el propio servidor de VMM.

Hay que añadir que es un Script proporcionado, aunque no soportado [disclaimer], por Microsoft, que se puede encontrar junto con el procedimiento completo de ejecución en esta página de Technet.

Para finalizar os incluyo el código del Script:
