VMware has released new ESX 6.0 Patch as of April 09, 2015.
A few of the Issues resolved in this patch:
After you enable Fault Tolerance on a Windows VM (Windows XP and later) configured with Virtual Hardware version 11 and vSphere 6.0 VM Tools, the virtual machine’s workload throughput will drop significantly.
When you upgrade a stateless ESXi host managed by Auto Deploy to ESXi 6.0, the host boots with the IP address 0.0.0.0. and creation of management interface on the host fails.
Stateless hosts might fail to apply a host profile during boot. An error message similar to the following is displayed: A specified parameter was not correct: dvsName
Release Date: Apr 9, 2015
Host Reboot Required: Yes
Virtual Machine Migration or Shutdown Required: Yes
