Bye bye SUSE Linux Enterprise Server for VMware
SLES for VMware has gone EoA on July 25, 2014, so there is currently no Linux distribution, that's bundled with your vSphere License. according to information from VMware they are not switching to a new Linux partner.
If you want to know what this means, the information can be found on this site: http://www.vmware.com/products/sles-for-vmware
Does this mean that Virtual Appliances will continue to be build on SLES, i don't know.
