Oracle licensing and support on VMware vSphere
As every one knows any good project get stopped by licensing. Oracle are up to there old tricks of trying to get more money or making virtual environment segmented (extra vCenter på Oracle hosts. staying on 5.5). It's properly the same with Microsoft Hyper-V and Citrix XenServer.
Before you just do as Oracle or there auditing partners says, I will recommend that you read this blog article: http://longwhiteclouds.com/2016/01/13/oracle-licensing-and-support-on-vmware-awaken-the-fud-in-your-datacenter/
