Description Robin Cernin 2017-01-30 09:02:41 UTC
Description of problem:

Bug description from LP:

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.

Requested a patch(backport) to Liberty of LP#1610693

Hi, it seems that the errata should be delivered on 	2017-Mar-29 (custom), could you update to the BZ please.

Comment 20 Radomir Dopieralski 2017-05-02 16:12:42 UTC
I verified that the "launch instance" dialog now only shows the count of instances from the currently selected project, and not from all projects.
