Microsoft has released System Center Virtual Machine Manager Update Rollup 2.1 (UR2.1)
This is a must update if you have installed Update Rollup 2 as it will fix the Dynamic Memory issue! This is an issue when all your virtual machines show to have a startup memory as 1MB. It will always display this and often not let you save as it is an invalid memory configuration.
