Posted on October 20th, 2008 in Tips | 1 Comment »

Few days ago, one of my virtual center machine was crashed and my Microsoft SQL database was corrupted without backup(damm!).

Basically setting up a brand new Windows 2003 machine is pretty simple but setup a new Virtual Machine took me 2 days. The most important is my VM template is go missing. The quick solution is search for VM template and register (add to inventory) again.

SSH into my ESX server using putty and search for VM template file with extension “.vmtx”.

[root@malaysiavmesx01 vmfs]# find /vmfs -name *.vmtx
/vmfs/volumes/465eeddb-89b75750-a52d-011aa0289d15/W2K3STD/W2K3STD.vmtx
/vmfs/volumes/465eeda7-2a63d436-724b-011aa0289d15/RHEL5/RHEL5.vmtx
