Emm, the arq unbind cmd is used of deleting instance.
Recently we donot support hot-plug/unplug device for instance. We only support binding devices when create instance and unbinding devices when delete instance.
Best Regards.

hi, Cyborg and nova team:
I am using cyborg with "Wallaby" release to manage my accelerator devices, while I'm trying to unbind the accelerator I found that the device was not actually unbound from the virtual machine.
Here are my questions:
1. What is the function of the arq unbind command in cyborg ?
2. How to unbind the accelerator which bounded to vm? Does nova or cyborg support this function now?
Here are my steps:
step1: openstack accelerator arq unbind ed205084-f58d-4fad-99b4-327a1398858f +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | uuid | ed205084-f58d-4fad-99b4-327a1398858f | | state | Unbound | | device_profile_name | ssd | | hostname | None | | device_rp_uuid | None | | instance_uuid | None | | attach_handle_type | | | attach_handle_info | {} | +---------------------+--------------------------------------+
step2: login vm and check the device, but it still here.
step3: stop vm and start vm, met the following error:
"nova.exception.AcceleratorRequestOpFailed: Failed to get accelerator requests: Cyborg returned no accelerator requests for instance ca77ef4e-421c-4c6c-9d76-7618a90ec921"
