As a VMware employee from 2007 to (January) 2014 the only time I recall any fear from leadership or product teams about HyperV was in 2008 or so when it was about to come out and then for a little while after it first came out. We knew we had a several year lead over Microsoft and wanted to make sure we stayed ahead of them feature-wise. After 2009 I don&#x27;t even recall people bringing up Microsoft or HyperV in conversation; we were more focused on competing with cloud platforms.
