Security - We will get there

One of my customers is paying vmware tons of money to run vSphere. It's really nice to work with the vCenter tools and I was definitely enjoying this product until I found it doesn't allow me to add virtual disk on the fly while the virtual instance was running. It says "License not available to perform the operation, Feature hotplug not licensed, requires need have have".

My practice on Vmware,Xen and virtual server/pc.

Vmware tips:

1. There are three options for host memory usage under host setting. You can choose to "Fit all virutal machine memory into reserved host RAM" to get the maximum performance and avoid un-predictable slowness sometimes.
