Using vSphere Mode for View Composer
In vSphere mode, View Composer can provision linked-clone desktops more quickly than in earlier releases.
Several View Composer features are available only in vSphere mode.
You must create linked-clone virtual machines on hosts that run ESX/ESXi 4 or later, and you must configure
linked-clone pools in vSphere mode, to take advantage of these View Composer and vSphere features:
n
Storing linked-clone virtual machines on local datastores
n
Redirecting disposable data to separate, non-persistent disks
n
Storing replicas and linked clones on separate datastores
n
Creating pools from a parent virtual-machine snapshot that uses hardware version 7
n
Using Sysprep customization specifications for linked-clone virtual machines
In addition, Sysprep is supported for linked-clones only on vSphere 4.1 software. You cannot use Sysprep
on vSphere 4.0 or VMware Infrastructure 3.5 software.
vSphere mode uses a new API that operates on ESX/ESXi 4 or later. With this API, View Composer needs to
make fewer API calls, which results in faster provisioning. ESX/ESXi 4 can take advantage of new hardware
features on the host machines.
After you create or edit a linked-clone pool in vSphere mode, you cannot revert it to the old API.
When you create a linked-clone pool, the ESX/ESXi version determines whether vSphere mode is available:
n
You can enable vSphere mode if you select a cluster that contains ESX/ESXi 4 hosts only. If you plan to
have ESX/ESXi 3.5 hosts in the cluster, do not enable vSphere mode. You cannot provision, refresh, or
recompose a linked-clone pool created in vSphere mode if the cluster contains an ESX/ESXi 3.5 host.
You enable this feature by selecting the Use vSphere mode for View Composer check box when you
create a linked-clone pool.
n
You must use vSphere mode if you select a single ESX/ESXi 4 host. You cannot deselect the Use vSphere
mode for View Composer check box.
n
You cannot use vSphere mode if you select an ESX/ESXi 3.5 host or a cluster that contains an ESX/ESXi 3.5
host.
