glance CLI always shows hw_vif_multiqueue_enabled='True'

[Gregory Thiemonge]

"openstack image show" reports incorrect properties when setting hw_vif_multiqueue_enabled

in devstack master (also reproduced on wallaby), I have an image with no hw_vif_multiqueue_enabled property

$ openstack image show -c properties -f value amphora-x64-haproxy
{'os_hidden': False, 'os_hash_algo': 'sha512', 'os_hash_value': 'fddf81f46b53ec0b3e1760cc0c1baa64578357003a00440ac4e0257af2af3556bb460f5fc38eab88e5aea43f997f59f75156bfdba92d9726f80bafba4e6a0911', 'owner_specified.openstack.md5': '', 'owner_specified.openstack.sha256': '', 'owner_specified.openstack.object': 'images/amphora-x64-haproxy', 'hw_architecture': 'x86_64', 'hw_rng_model': 'virtio'}

Set the hw_vif_multiqueue_enabled property to True, it is ok:

$ openstack image set --property hw_vif_multiqueue_enabled=True amphora-x64-haproxy
$ openstack image show -c properties -f value amphora-x64-haproxy
{'os_hidden': False, 'os_hash_algo': 'sha512', 'os_hash_value': 'fddf81f46b53ec0b3e1760cc0c1baa64578357003a00440ac4e0257af2af3556bb460f5fc38eab88e5aea43f997f59f75156bfdba92d9726f80bafba4e6a0911', 'owner_specified.openstack.md5': '', 'owner_specified.openstack.sha256': '', 'owner_specified.openstack.object': 'images/amphora-x64-haproxy', 'hw_architecture': 'x86_64', 'hw_rng_model': 'virtio', 'hw_vif_multiqueue_enabled': True}

Set the property to False (or false), it is not ok, image show still returns "True"

$ openstack image set --property hw_vif_multiqueue_enabled=False amphora-x64-haproxy
$ openstack image show -c properties -f value amphora-x64-haproxy
{'os_hidden': False, 'os_hash_algo': 'sha512', 'os_hash_value': 'fddf81f46b53ec0b3e1760cc0c1baa64578357003a00440ac4e0257af2af3556bb460f5fc38eab88e5aea43f997f59f75156bfdba92d9726f80bafba4e6a0911', 'owner_specified.openstack.md5': '', 'owner_specified.openstack.sha256': '', 'owner_specified.openstack.object': 'images/amphora-x64-haproxy', 'hw_architecture': 'x86_64', 'hw_rng_model': 'virtio', 'hw_vif_multiqueue_enabled': True}

The value is False (but it is a string not a boolean) in the DB:

$ mysql -u root glance -e "select * from image_properties where image_id = '394ec5e4-3aab-47e8-a36f-dfdba732994b' and name = 'hw_vif_multiqueue_enabled' \G"
*************************** 1. row ***************************

updated_at: 2022-11-09 07:43:01

Unsetting the property doesn't work:

$ openstack image unset --property hw_vif_multiqueue_enabled amphora-x64-haproxy
property unset failed, 'hw_vif_multiqueue_enabled' is a nonexistent property
Failed to unset 1 of 1 properties.

Note: this is an issue only with the CLI, the property is correctly read by nova when creating the VM.
