I've made an environment in vCloud Director using nested ESXi 5.5, but after upgrading the VMs to ESXi6 (RC) the VMware Tools for Nested ESXi are gone. This leads to loads of problems, because vCloud Director finds the VMs to be in an inconsistent state. This kills networking and makes the VMs basically useless. Manually re-installing the vib doesn't work (I've tried maintenance mode and lowering the Host Image Profile Acceptance level) - it will skip the vib.
Does anyone have any suggestions how to get the VM to be functional again?
ESXi 6.0 comes with VMware Tools for Nested ESXi pre-installed. There should be a vmtoolsd process running on your ESXi 6.0 guest. If not, perhaps the log files give some indication of what happened to it?
