It's a bug in the latest SDK version, you need to access to the ADT manually
cd path_of_android/tools/
and then type
android avd
Pregunta
I downloaded latest Eclipse and Android SDK packages in full (including ARM System Image) and coupled them with ADT. But I couldn't create virtual machines. When I click "OK" it does not happen anything. Is there any reason behind this?

select android sdk manager from the window tab in eclipse, then once that is launched, open up tool from the top menu, then create your virtual device from there. I don't know why this works but I was able to create a virtual device using this workaround.
Google has accepted this is an issue in SDK 22.6 and promised to fix it in 22.6.1 release.
