A vApp allows you to perform resource management and certain other management activities such as power operations for multiple virtual machines at the same time. You can think of the vApp as the container for the virtual machines, and you can perform the operations on the container.

When you create a vApp, you can add it to a folder, standalone host, resource pool, cluster enabled for DRS, or another vApp.

Verify that one of those objects is available in your datacenter.

A standalone host that is running ESX 4.0 or greater.

A cluster that is enabled for DRS.

1

Navigate to an object that supports vApp creation and select the New vApp icon (create new vApp icon).

2

In the Resource Allocation page, allocate CPU and memory resources to this vApp.

a

Allocate CPU resources for this vApp.

Option

Description

Shares

CPU shares for this vApp with respect to the parent's total. Sibling vApps share resources according to their relative share values bounded by the reservation and limit. Select Low, Normal, or High, which specify share values respectively in a 1:2:4 ratio. Select Custom to give each vApp a specific number of shares, which express a proportinal weight.

Reservation

Guaranteed CPU allocation for this vApp.

Reservation Type

Select the Expandable check box to make the reservation expandable. When the vApp is powered on, if the combined reservations of its virtual machines are larger than the reservation of the vApp, the vApp can use resources from its parent or ancestors.

Limit

Upper limit for this vApp's CPU allocation. Select Unlimited to specify no upper limit.

b

Allocate memory resources for this vApp.

Option

Description

Shares

Memory shares for this vApp with respect to the parent's total. Sibling vApps share resources according to their relative share values bounded by the reservation and limit. Select Low, Normal, or High, which specify share values respectively in a 1:2:4 ratio. Select Custom to give each vApp a specific number of shares, which express a proportinal weight.
