Yesterday, Microsoft confirmed they would be lifting the licensing by physical server restriction that made using features such as VMotion & XenMotion an expensive option if Microsoft software was used. I spoke about in a previous post. The license restriction will be lifted on 41 server products, exactly which ones it isn't yet clear.
Also, the EULA isn't available just yet so the exact T&C aren't known, so lets hope there isn't any nasty caveats that spoil this good news.
The news licensing comes into force on September 1st so you don't have to long to wait. I will keep you updated to whether there are any surprises.
