It turns out the version of vmtools that comes with ESXi v6 u2 (10.0.6) is buggy. If you upgrade to version 10.0.9 it resolves this issue – it is listed in the release notes under Attempts to take a quiesced snapshot in a Windows Guest OS fails.

We have not installed this version yet to confirm it fixes it but I figured I would share as we have been wasting time trying to troubleshoot and fix vmtools when we have the buggy version.

FYI, if you’re on ESXi v6 u2, your VM’s will show as ‘up to date’ and will be vmtools version 10.0.6. You will have to install 10.0.9 manually. We are testing whether we can just install it on the host and then run automatic upgrade again.
