For example, a virtual machine with two virtual CPUs and 1GB RAM with CPU and memory shares set to
Normal has 2x1000=2000 shares of CPU and 10x1024=10240 shares of memory.
The relative priority represented by each share changes when a new virtual machine is powered on. This affects
all virtual machines in the same vDC.
Resource Allocation Reservation
A reservation specifies the guaranteed minimum allocation for a virtual machine.
vCloud Director allows you to power on a virtual machine only if there are enough unreserved resources to
satisfy the reservation of the virtual machine. The vDC guarantees that amount even when its resources are
heavily loaded. The reservation is expressed in concrete units (megahertz or megabytes).
For example, assume you have 2GHz available and specify a reservation of 1GHz for VM1 and 1GHz for VM2.
Now each virtual machine is guaranteed to get 1GHz if it needs it. However, if VM1 is using only 500MHz,
VM2 can use 1.5GHz.
Reservation defaults to 0. You can specify a reservation if you need to guarantee that the minimum required
amounts of CPU or memory are always available for the virtual machine.
Resource Allocation Limit
Limit specifies an upper bound for CPU and memory resources that can be allocated to a virtual machine.
A vDC can allocate more than the reservation to a virtual machine, but never allocates more than the limit,
even if there are unused resources on the system. The limit is expressed in concrete units (megahertz or
megabytes).
CPU and memory resource limits default to unlimited. When the memory limit is unlimited, the amount of
memory configured for the virtual machine when it was created becomes its effective limit in most cases.
In most cases, it is not necessary to specify a limit. You might waste idle resources if you specify a limit. The
system does not allow a virtual machine to use more resources than the limit, even when the system is
underutilized and idle resources are available. Specify a limit only if you have good reasons for doing so.
Configure Virtual Machine Resource Allocation Settings
You can configure the resource allocation settings (shares, reservation, and limit) to determine the amount of
CPU, memory, and storage resources provided for a virtual machine.
For more information about shares, reservations, and limits, see “Resource Allocation Shares,” on page 97,
“Resource Allocation Reservation,” on page 98, and “Resource Allocation Limit,” on page 98.
Prerequisites
A reservation pool vDC.
Procedure
1 Click My Cloud.
2 In the left pane, click VMs.
3 Select a virtual machine, right-click, and select Properties.
4 Click the Resource Allocation tab and set the priority, reservation, and limit for CPU and memory.
5 Click OK.
