This has come up a few times via support questions from operators
that have a nova cell database out of sync with the placement
database resulting in a mismatch in compute nodes to provider
uuids and they just want to wipe the placement database and rebuild
it from the current data in nova. This provides a document with the
high level steps to do that.

While we do not have an automated fix for bug 1849479 this provides
a troubleshooting document for working around that issue where
allocations from a server that was evacuated from a down host need
to be cleaned up manually in order to delete the resource provider
and associated compute node/service.
In general this is also a useful guide for linking up the various
resources and terms in nova and how they are reflected in placement
with the relevant commands which is probably something we should
do more of in our docs.

Keystonemiddleware compares the roles of the service_user with
[Keystone_authtoken]/service_token_roles, we need to explain this so
that users don't get confused.
For example:
Nova send request to neutron with both service_user_token and
user_token, neutron first sends them to Keystonemiddleware for
authenrication, Keystonemiddleware will compare service_user's role
with [Keystone_authtoken]/service_token_roles which configured in
neutron, then decide whether to fetch user_token based on the result.

This was added to handle gate issues seen with libvirt 1.2.2. We haven't
supported that version of libvirt for some time and we don't enable this
in the gate anymore. Deprecate it and remove unnecessary references to
it from tests and the support FAQ document.

This took me a good hour to suss and while there were a couple of Google
hits for it, the top suggestion was to use TCP (rather than SSH) and
disable all security, which is rarely good advice.
Paste an sample error and link to the doc where you can find advice of
resolving the issue.

We typically use '-' for H2-type headers and '~' for H3-style. This
document was using the opposite which was mighty confusing for your dear
editor. Simply switch them around and reduce that confusion.

A recent thread in the mailing list [1] reminded me that we
don't have any documentation for the service user token feature
added back in ocata under blueprint use-service-tokens.
This change adds a troubleshooting entry for when using service
user tokens would be useful, and links to it from two known
trouble spots: live migration timeouts and creating images.

Closes-Bug: #1809165
If the compute endpoint in the service catalog is configured
for /v2 legacy compat mode, microversions in the request are
silently ignored by the LegacyV2CompatibleWrapper. This
adds a troubleshooting entry for that situation.
At this point, we might want to consider deprecating or at
least logging warnings if microversions are requested and
LegacyV2CompatibleWrapper strips them out, but that's fodder
for a separate change.
