You don't need to link against anything other than the Open VM Tools library.

I'm fine with licensing as GPL2.  You have my blessing.

I do recommend somebody does a proper code review.

Thank you,

While I'm not an expert, I guess I have a fair understanding of the
stuff ;-)

Nice! As you noted yourself, this is the LGPL (2.1), which is perfectly
compatible to the GPL 2 (and 3). So there is no problem at all licensing
the plugin under the GPL.

Do you need to link the plugin against anything else but that library?
In that case, make sure that the other libs are GPL-compatible as well.
However, looking at the project website, all required stuff seems to be
available under GPL-compatible licenses (which is very surprisingly nice
imho :-)).
