In the last few releases of vCloud Director more and more capabilities have been added into the HTML5 interface to bring it in line with the older Flex UI. While it has come a long way there are still a few things (refer to the release notes) missing that some people may do on a regular basis. In vCloud 10.0 when you attempt to browse to the Flex UI by appending /cloud to the end of your vCloud URL it will automatically redirect to the HTML5 interface.

The old Flex UI hasn’t been removed just yet and there is still a way to enable it. So whether there is an option you don’t have in the HTML5 interface yet or you have been working with the Flex UI for so long you are just more comfortable with it, here is how you enable it.

There are 2 options available, you can enable it for all users or just the system administrators.

Login via SSH to each of your vCloud Cells as the root user,

To enable it for all users run the following command,

/opt/vmware/vcloud-director/bin/cell-management-tool manage-config -n flex.ui.enabled -v true

If you want to only enable it for the system administrators then you can run the following command,

/opt/vmware/vcloud-director/bin/cell-management-tool manage-config -n flex.ui.enabled -v sys-admin-only

If you have more than one vCloud Cell make sure you run it on each of your cells.

Then restart the vmware-vcd service on each cell you have made the change

service vmware-vcd restart

And we are back,

If you want to disable the old Flex UI at a later stage you can run the following command to do so,

cell-management-tool manage-config -n flex.ui.enabled -v false
