If I have four virtual machines running on a windows server 2003 can we share a memory pool across all of them since they will never be using it at the same time as the others because they are doing load balancing?

Thanks. We'll let you know when a new response is added.

You don’t mention what virtualization software you are using. Some (VMWare in particular) allow over-subscription of memory but most do not. In other words, you can have a host machine with 8GB of RAM and 4 VMs with each allocated 4GB (16 total). Many (most?) virtualization software will not allow you to run with more than your physical RAM allocated to your running VMs.

    ...they will never be using it at the same time as the others because they are doing load balancing? That seems odd. I'd expect load-balancing to increase the chance of concurrent usage of any shared resource. Tom
