Provision VMware vApp

You can create a vApp directly on the ESX host or cluster level, or as part of an existing resource pool or vApp.

Follow these steps:

1. From the host or clusters level in the Explore pane, right-click the ESX host or cluster.

   A pop-up menu opens.

2. Select Provisioning, Provision VMware vApp.

   The Create New vApp dialog appears.

3. Specify the following fields and click OK.

   Name

   Identifies the vApp.

   CPU Shares

   Specifies CPU shares for this vApp with respect to the total CPU resources of the parent host, resource pool, or vApp. Sibling vApps share resources according to their relative share values bounded by the reservation and limit. Specify a number of shares which expresses the appropriate proportional weight.

   For example, assume that you have vApp1 and vApp2 on a host and each has 1000 CPU shares. The weight is equal and each vApp can allocate 50 percent CPU time of the parent host. However, if vApp1 has 2000 CPU shares and vApp2 has 1000, then the weight is not equal. The total number is 3000 shares, and 1000 shares represent 33.3 percent, and 2000 shares represent 66.6 percent. So vApp1 can allocate 66.6 percent and vApp2 can allocate 33.3 percent of CPU time.

   CPU Reservation

   Specifies the guaranteed CPU allocation for this vApp.

   CPU Unlimited

   Disables the CPU limit setting. The actual limit is now set to the available physical resource.

   CPU Limit

   Specifies the upper limit for the CPU allocation for this vApp. You can usually accept the default.

   Memory Shares

   Specifies memory shares for this vApp with respect to the total memory resources of the parent resource pool or vApp. Sibling vApps share resources according to their relative share values bounded by the reservation and limit. Specify a number of shares which expresses the appropriate proportional weight.

   For example, assume that you have vApp1 and vApp2 on a host and each has 1000 memory shares. The weight is equal and each vApp can allocate 50 percent memory of the parent host. However, if vApp1 has 2000 memory shares and vApp2 has 1000, then the weight is not equal. The total number is 3000 shares, and 1000 shares represent 33.3 percent, and 2000 shares represent 66.6 percent. So vApp1 can allocate 66.6 percent and vApp2 can allocate 33.3 percent of memory.

   Memory Reservation

   Specifies the guaranteed memory allocation for this vApp.

   Memory Unlimited

   Disables the memory limit setting. The actual limit is now set to the available physical resource.

   Memory Limit

   Specifies the upper limit for the memory allocation for this vApp. You can usually accept the default.

   The new vApp appears in the Explore pane.
