Apply a limit of 1GB of RAM to a VM when it has 4GB allocated

Duncan Epping has hit the nail on the head again.

I totally agree, I have seen first hand the horror of memory limits and the impact it can have on a guest.

A customer asked me to assist resolve a performance issue with a VM. The VM was Windows Server 2000, it was allocated 4GB of RAM. I opened the VI client performance tab and was shocked to see the Memory ballon running at 3GB solid. Some bright spark created a VM memory limit of 1GB on the Windows 2000 template, the template was allocated 1GB of RAM. Unfortunately this VM guest on deployment was granted more memory and no one thought to look for a hard coded memory limit.

Here is the result of removing the limit.
