Public bug reported:
I have recently upgraded my cluster to Liberty for all projects. Now,
when I create new instances, I frequently get an incorrect quota warning
from the instance creation workflow, despite having plenty of available
quota:
"The requested instance cannot be launched as you only have 0 of your
quota available."
The issue is happening within the _get_tenant_compute_usages() check.
That function determines (correctly) that I am able to list instances in
all projects, so passes 'all_tenants' to the nova api. That results in
an api call that looks like this:
"GET /v2/<tenantid>/servers/detail?all_tenants=True&tenant_id=<tenantid>
HTTP/1.1"
Nova replies with a list of every instance in my entire cloud, 719 at
last count. The call is very slow and, of course, 719 is many more than
my instance quota for the current project, so Horizon determines that I
am over quota.
Note that this issue didn't appear when I was running Liberty Horizon with Kilo
Nova (so maybe this is a bug or change in the nova-api) Best I can tell, the
offending code in Horizon is still present in the git head.
