I particularly enjoy using a web browser to administer GUI appliances. In the case of oVirt, it does become a little painful to do the Chrome-zoom-click on my massive 4k Android phone. It appears the oVirt devs have also seen this pain point and have released an Android app to make adminstration easier on Android.
moVirt (mobile oVirt) makes common administrative tasks easier – migrating VMs, spinning down servers, spinning up stopped servers, etc.
moVirt has become an essential tool that I use on an infrequent basis. Now, if I can only figure out how to spin up VMs with Puppet.
