[TUTORIAL] Migrating Virtual Machines without Vmotion
Guys are hard at work with the labs at the moment here in sunny Hobart, and so I begin trawling the blogs (as is my want). I discovered this brilliant little gem from Mike DiPetrill’s blog.
This post demonstates the awesome power of the Vmware API and the ease of use we get from the VI Toolkit for Windows! The script will move a VM from one ESX host to another, without making use of VMware VMotion. The drawback is that the VM becomes unresponsive for a period of time (usually a few seconds). This is roughly functionally equivalent to Microsoft’s Quick Migration feature, except that this was done in 130 lines of script.
