[Bug 2102161] Re: Live-migratable flag ignored for devices with physical_network tag
they are not ment to
it would be a sever regression if a vm with a sriov port that was marked as "live_migratable": false
could not live migrate via the existing sriov hot plug live migration

Title:
Live-migratable flag ignored for devices with physical_network tag
Status in OpenStack Compute (nova):
Invalid
Bug description:
The live_migratable flag is ignored when a PCI device has the physical_network tag.
As a result, instances using such devices do not behave as non-live migratable.
Instead, they continue to migrate using the legacy VIF unplug → live migrate → VIF plug procedure, despite being configured as non-live migratable.
Example Affected Configuration:
[pci]
device_spec = { "vendor_id":"8086", "product_id":"10ca", "address": "0000:06:", "physical_network": "physnet2", "live_migratable": false}
Impacted release is Epoxy
