Kernel 3.14 Final was just released today. It would seem likely that Ubuntu 14.04 LTS will be released with this version. Of course VirtualBox requires a very simple module recompile to work - and virt-manager will work. So there is a potential problem for VMware because of the LTS question. I don't use Fedora except in a VM but I'm pretty sure that will be the case for this distro as its a rolling release.
Naturally I expect no answer from VMware concerning kernel support. Patches may be OK for individuals or small companies but for larger companies - who knows?
