I'm not a licensing expert either.  ;-)

vmGuestLib.h is part of the 'Open Virtual Machine Tools' hosted here:  http://sourceforge.net/projects/open-vm-tools/

This is the license displayed at the top of the vmGuestLib.h file.

Would it be possible to license this plugin with the standard Collectd GPL2 license?

I haven't had a look at your code yet, but I'd like to comment this:
unless the VMWare license explicitly forbids to do so, the plugin may
either be put under a BSD-like license (which permits linking with
proprietary stuff) or the GPL using the "linking exception" [1].

Note, though, that this is a license change, so all authors and
contributors of the plugin have to agree about it.
