Any precompiled version will not be able to do a clean shutdown of unRAID. The shutdown routine in open-vm-tools has to be patched to make that happen.
I have the same bond0 error that StevenD has. It's not actually a network error, but it is not loading a driver for storage device and therefore is not able to read anything fro the USB.
So far two people have asked fro the scripts I used for 6.3 - hopefully one of them will have better luck getting this working.
It is not a simple task to build this plugin. Every time the unRAID kernel is changed, you have to create new patches to get open-vm-tools to work with the new kernel version. This is also why I never build for beta and RC's as it would take me a full 8-10 hour day to get it building again.
I no longer use unRaid under ESXi.
I had tried setting up a development VM, but was not able to get 6.4 to boot correctly.
If anyone else wants to take on building this, they can send me a message to get a copy of my build scripts.
