As you know, the number of Virtual Machines per host depends on available
resources (CPU, RAM, Disk), as well as the demands of the image.
As a general guide, I have found the following to be reasonable. Other admins,

Hello,
I was able to successfully capture a base image.
I have added the image to the image group.
However, when I try to make a reservation, or create a new image,
It eventually fails. I watch the VM server and see that a new VM was started.
It does start a new VM with the correct MAC addresses,
