Comment 7 for bug 1595206

https://review.openstack.org/#/c/281134 (complete refactoring of this part of vmware driver in Nova) is not going to be back ported to stable/mitaka, thus, we should restraint from cherry-picking it do 9.0/mitaka downstream branch, unless absolutely necessary.

IMO, the workaround described by Alexander in #6 and increasing of the NFC timeout value (https://kb.vmware.com/kb/2038497) should be sufficient for 9.x.
