If you are planning to utilize the new “instant clone” capability in Horizon View 7, you need to understand the operational impacts that come along with the feature. Specifically, as described in the VMware KB article below, new considerations are required for putting ESXi hosts with instant clones into maintenance mode.
VMware has a packaged Admin UI for Horizon View 7 that provides administration capability without requiring the installation of Adobe Flash. The Admin UI works like a thinapp package and supports View administration only, no external browsing. There are a few known issues described with workarounds along with the download link in VMware KB 2144303.
I have used the Admin UI for a little while and have found it very handy. I especially like the portability of the single executable.
