OpenStack Icehouse Reset Incorrect Quota Count for Nova

Sometimes when VM is deleted in not-so-correct way quota counters displayed in Dashboard => Project => Overview may not update correctly as well.

You may see that number of VMs/vcpus/RAM for tenant displayed on this page does not match actual values. For example it may display “Instances used 8 of 10” while you have only 5 VMs in this tenant.

OpenStack Glance Authentication and Changed Swift Password

Input data: OpenStack Icehouse, glance with swift backend. Admin username and password for swift service were changed. After this requests to download some images started to fail.

# glance --debug image-download <image_id> --file image_store_to --progress

returns 500 error for some image_ids and works for other.

in glance-api service log I see that for some reason previous user/password is still in use:

Debian, Libvirt, Non-root

I’m playing with OpenStack and decided to bring up a testing environment on my home Debian computer.

I’m using KVM virtualization, launching VMs as non-root user and hit an issue not described in official documentation.
