Configuring virtual machine (VM) reservations is an important component in maintaining a stable Foglight monitoring environment.
Setting both CPU and memory reservations, ensures that Hyper-V will dedicate multiple whole processors and a fixed amount of memory whenever the VM is running.
To configure CPU processors and memory for a virtual machine, please follow the steps as described in this Microsoft blog post
Turn off the Virtual Machine and get an account with local administrator permissions.
Open Hyper-V Manager. Click Start, point to Administrative Tools, and then click Hyper-V Manager.
In the results pane, under Virtual Machines, select the virtual machine that you want to configure.
In the Action pane, under the virtual machine name, click Settings. Then, in the navigation pane, click the appropriate hardware setting as described in the following steps.
To configure the memory, click Memory. On the Memory page, specify the new amount of memory.
To configure the processor, click Processor. If multiple processors are supported by the guest operating system, specify the number of processors to assign to the virtual machine. Then click OK.
To set processor affinity, click Processor, and configure the Virtual machine reserve (percentage) to “100”
