vSphere 5.5 U2 C# Client can now edit Hardware Version 10 VMs

Instead of getting an error message when trying to edit Virtual Machines with Hardware Version 10 you can now reconfigure these machines with the legacy C# client. Understandably you can only edit pre-5.1 features. All 5.1/5.5 features are still only available with the vSphere Web Client.

The swap file size can be calculated with the formula (.vswp File = Allocated Memory - Memory Reservation). As per default, the reservation is set to 0, so the .vswp file size is equal to the amount of virtual memory.
