Re: Question on how people are configuring their VM computers
Hi Norvin
In our environment all VM computers configured with largest amount of resources (MEM, CPU) needed by an image.
I.e. if you have an image which needs 4 vCPU/8GB of memory then ALL VM computers would have4 vCPU and 8GB.
The VM computer configuration basically means 'up to' specified resources, it doesn't mean that all images will be loaded with max resources (4vCPU/8GB).
When you make a reservation/reload request for an image, it will be loaded on any VM computers which has adequate resources, but the image will be loaded with resources you specify for the image. I.e. you have WinXP image with 1vCPU/1GB, once you load it on a VM computer it will have exactly the resources you specified for the image (1vCPU/8GB).
I hope it helps.

My problem with this method is that I have obviously limited the total numbers as it will not load 8GB vm computers with a 1GB image. I would like to know if I configure the the VM computers all as 8GB VM's will the vcl code stop any over provisioning the esxi hosts?

Thanks all for the quick response. While I was testing some options on my vcl test environment I started to see the scenario's you all have described. That is what brought the original question up. You have provided me with the confirmation that I was looking for to move forward. Thanks
