[<CommonParameters>]Description
The Set-VMMemory cmdlet configures the memory of a virtual machine.
Examples
Example 1
PS C:\>Set-VMMemory TestVM -DynamicMemoryEnabled $true -MinimumBytes 64MB -StartupBytes 256MB -MaximumBytes 2GB -Priority 80 -Buffer 25Enables dynamic memory on virtual machine TestVM, sets its minimum, startup, and maximum memory, its memory priority, and its buffer.
Parameters
