Reservation pool virtual datacenters support the ability to control resource allocation at the virtual machine level. Users with the necessary rights can customize the amount of resources that are allocated to their virtual machines.

Use the resource allocation settings (shares, reservation, and limit) to determine the amount of CPU, memory, and storage resources provided for a virtual machine. Users have several options for allocating resources.

  • Ensure that a certain amount of memory for a virtual machine is provided by the virtual datacenter.

  • Guarantee that a particular virtual machine is always allocated a higher percentage of the virtual datacenter resources than other virtual machines.

  • Set an upper bound on the resources that can be allocated to a virtual machine.
