I am trying to find any Pros/Cons for using Dynamic Disk for Guest vm's. Any concerns using standard disk for the OS and Dynamic Disk for the Application partition?
IMHO I prefer use standard disks. Also some Microsoft notes sugges in SAN enviroment (that are similar to virtual enviroment) to use standard disks.
If you use a 1:1 mapping between volume and vmdk you can simple resize the disk (is little more complicated if for version before Vista).
One reason to use dynamic disk could be have a single volume greater that 2 TB.
