Hyper-V Resource Control

Virtual Machine Reserve (percentage) – this value says how much CPU is kept aside for the running Virtual Machine.

Percent of total system resources – this is a precent of a Virtual Machine processor time, that is measured by how many processors are assigned to the virtual machine

Virtual Machine Limit (percentage) – this is a percent of CPU that the running Virtual Machine is not allowed to go over the top of

Percent of total system resources – this is percent of a VM processor time, that is measured by how many processors are assigned to the physical computer

Relative Weight – this is used to decide how CPU is distributed. (Basically a virtual machine with the higher weight (say 500) will get twice the CPU time as a virtual machine with a weight lower weight (say 400).

Example:

Basically on a 1 CPU and 4 Core computer you can run 40 1 CPU Virtual Machines if their reserve is 10%.

If you get this error when you try to access your essentials reports under Reporting there is a quick and easy way to fix it.

Solution:

• Open your SQL Management Studio.
• Then browse to SUSDB database and select it, right click and select properties.
• Under properties select permissions. There should be only 3 entries, which are Domain\Username, NT Authority\Network Service and COMPUTERNAME\WSUS Administrators. You want Domain\Username user, so select that one.
• Under Explicit tab scroll down until you see Select. Tick it under Grant and press OK. Now go and try to run your reports again.
