Fast Provisioning of Virtual Machines
Fast provisioning saves time by using linked clones for virtual machine provisioning operations.
A linked clone is a duplicate of a virtual machine that uses the same base disk as the original, with a chain of
delta disks to track the differences between the original and the clone. If fast provisioning is disabled, all
provisioning operations result in full clones.
A linked clone cannot exist on a different vCenter datacenter or datastore than the original virtual machine.
vCloud
Director creates shadow virtual machines to support linked clone creation across vCenter datacenters
and datastores for virtual machines associated with a vApp template. A shadow virtual machine is an exact
copy of the original virtual machine. The shadow virtual machine is created on the datacenter and datastore
where the linked clone is created. You can view a list of shadow virtual machines associated with a template
virtual machine. See “View Shadow Virtual Machines Associated With a Virtual Machine,” on page 82.
Fast provisioning is enabled by default on organization vDCs. Fast provisioning requires vCenter 5.0 and ESXi
5.0 hosts. If the provider vDC on which the organization vDC is based contains ESX/ESXi 4.x hosts, you must
disable fast provisioning. See “Edit Organization vDC Storage Settings,” on page 48.
View Shadow Virtual Machines Associated With a Virtual Machine
Shadow virtual machines support linked clones of virtual machines that are associated with vApp templates
across vCenter datacenters and datastores.
A shadow virtual machine is an exact copy of the original virtual machine that vCloud Director creates on the
datacenter and datastore where a linked clone is created. See “Fast Provisioning of Virtual Machines,” on
page 82.
Procedure
1 Click the Manage & Monitor tab and click Organizations in the left pane.
2 Right-click the organization name and select Open.
3 Click the My Cloud tab and click VMs in the left pane.
4 Right-click the virtual machine and select Properties.
5 Click the Shadow VMs tab.
This tab appears only for virtual machines that have associated shadow virtual machines.
vCloud Director shows a list of shadow virtual machines associated with the virtual machine. This list includes
the name in vCenter of each shadow virtual machine, the datastore that each shadow virtual machine exists
on, and the vCenter server that the shadow virtual machine belongs to.
