It is a pain in the rear to generate XML on the fly. There just is not a fun way of doing it. Unfortunately this is what is required when creating, cloning, and altering VMs with the VI Perl toolkit. I went ahead and creating a very simple Perl script that will take HTML GET variables from the...

Posted by: Joe Foran
DataCenter, Joseph Foran, Virtualization, VMware ESX

At the risk of sounding like a commercial, Hyperic HQ is my leading-choice for agent-based systems management tools to handle both VMware and non-VMware systems. Personally I tend to prefer non-agent-based systems, but the Hyperic tools work,...

VMware network drivers do not PPTP or L2tPass go. Do not collect $200!
