WalkthroughThe PR updates the migrate_with_bridge_type_interface config and test. Config: adds VM lifecycle controls and a Linux-only gate, replaces per-bridge variant blocks with top-level bridge_name and iface_type="bridge", renames steps start_with_interface → start_with_iface and hotplug_interface → hotplug_iface, and restructures migration variant blocks. Test: replaces Estimated code review effort🎯 3 (Moderate) | ⏱️ ~25 minutes 🚥 Pre-merge checks | ✅ 3✅ Passed checks (3 passed)

- Around line 36-38: The config defines iface_base_attrs but the test builds
iface_attrs directly (see iface_attrs usage in the Python test), so either
remove the unused iface_base_attrs entry or document its purpose; to fix, delete
the iface_base_attrs = {...} line from migrate_with_bridge_type_interface.cfg if
it’s not used, or prepend a one-line comment explaining it’s a
placeholder/example for future tests, or alternatively update the test to read
and use iface_base_attrs when constructing iface_attrs (referencing the
iface_base_attrs symbol in the config) so the config and test stay consistent.

76-80: Consider defensive handling for emptynetdstparameter.If
netdstis empty or not set,bridge_namebecomes an empty string, resulting in{'bridge': ''}being set iniface_attrs['source']. This could cause issues during interface attachment.Consider adding validation:
🛡️ Suggested defensive check
bridge_name = params.get('netdst', '').split(',')[0] + if not bridge_name: + test.error("netdst parameter is required but not set") iface_attrs['source'] = {'bridge': bridge_name}

🗑️ Suggested removal

cleanup_nvramfunction is removed as suggested, this import should also be removed.🗑️ Conditional removal

- Around line 70-97: The code currently derives bridge_name only from
params.get('netdst') which can be empty; update the logic that sets bridge_name
so it first uses params.get('bridge_name') (or params['bridge_name'] if you want
fail-fast) and falls back to params.get('netdst').split(',')[0] only if
bridge_name is still empty, and if no bridge name is found raise/abort early
with a clear error before assigning iface_attrs['source']; adjust the place that
sets iface_attrs (the iface_attrs dict creation and the line setting
iface_attrs['source']) and ensure network_base.setup_ovs_bridge_attrs(params,
iface_attrs) still runs after a valid source is set.

Test pass. |

196-196:new_xmlis assigned but never used.
new_xml = vm_xml.VMXML.new_from_inactive_dumpxml(vm_name)is a leftover from the old implementation. It makes an unnecessary libvirt call and also makesfrom virttest.libvirt_xml import vm_xml(line 15) redundant given the directVMXMLimport on line 17.♻️ Proposed cleanup
