If you’ve ever migrated clusters or joined VM’s from a different cluster, I’m sure you’ve run into the bug where memory limits are set on the VM’s automatically. To remove this, simply use the powerful oneliner below!

 Get-VM | Get-VMResourceConfiguration | where {$_.MemLimitMB -ne '-1'} | Set-VMResourceConfiguration -MemLimitMB $null
