External guest users are given a COS called guest that is not visible from the Horizon Workspace Administrator Web interface. This COS determines the data-va virtual machine that guest users are provisioned on.

By default, all data-va virtual machines are enabled in the host pool on the guest COS. You must modify this COS to specify the data-va virtual machines to use.

If you want guest users to be assigned to a specific data-va virtual machine or you want to change the machines that are enabled, modify the guest COS to enable the machine you want to use.

1

Log in to the new data-va virtual machine as the root user.

2

Change to the Zimbra user.

su - zimbra

3

Run the zmprov command on the ID of the data-va virtual machine you want to use.

zmprov gs data-vahzndataId

Horizon Workspace uses this ID format: 45c3e0ce-5617-4bf7-9c92-334ab36f9f7b.

4

Find the names of the data-va virtual machine nodes that are in the guest COS host pool.

If the guest COS has not been modified to add specific data-va virtual machines to the host pool, this command does not return a value. If you use the default value, all data-va virtual machines are enabled in the host pool.

a

Modify the guest COS host pool to add, remove, or replace a data-va node using one of the following commands.

Add a data-va node to the host pool.

zmprov mc guest +hzndataHostPool data-vaname.com|ID

Remove a data-va node from the host pool.

zmprov mc guest -hzndataHostPool data-vaname.com|ID

Replace all data-va virtual machines in the host pool.

zmprov mc guest hzndataHostPool data-vaname.com|ID

You can permanently remove the data-va virtual machine if there is a problem with it.
