Hi,
This is about review:
https://review.openstack.org/#/c/156633/
1 line, can be controversial
Its purpose is to add the possibility not to use libguestfs for data
injection in nova, even when installed.
Not discussing about the fact that libguestfs should be preferred over
fuse mounts for data injection as much as possible because mounts are
more subject to causing security issues (and already have in the past
nova releases).
However, there are a lot of potential cases when libguestfs won't be
usable for data injection
This was the case here (fixed):
https://bugzilla.redhat.com/show_bug.cgi?id=984409
I entcountered a similar case more recently on powerkvm 2.1.0 (defect
with the libguestfs)
So just saying it could be good adding a simple config flag (set to True
by default, to keep the current behaviour untouched) to force nova not
using libguestfs without having to uninstall it and thus prevent other
users on the host from using it.
regards
raphael
