Description of problem:
Cold migrate VM with ovn localnet transfer network hit unexpected failure: ---------------------------------------------------------- [ 0.0] Setting up the source: -i libvirt -ic vpx://administrator%40vsphere.local@10.***/data/host/10.***?no_verify=1 -it vddk mtv-rhel7-9-staticip virt-v2v: error: exception: libvirt: VIR_ERR_INTERNAL_ERROR: VIR_FROM_ESX: internal error: curl_easy_perform() returned an error: Couldn't connect to server (7) : Failed to connect to 10.*** port 443: No route to host ----------------------------------------------------------- Rerun the plan successfully without any change. Check in pod with ovn localnet as default route: it failed to connect outside when the pod is created, wait for a while, it can connect outside successfully.
Version-Release number of selected component (if applicable):
MTV 2.8.0
How reproducible:
30%
Steps to Reproduce:
1) Create NodeNetworkConfigurationPolicy to use another interface: eno8403 to create ovs-bridge: br-withvlan, and mapping to localnet: tenantblue
apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata:
name: br-withvlan
spec:
desiredState:
interfaces:
- name: br-withvlan
type: ovs-bridge
state: up
bridge:
options:
stp: true
port:
- name: eno8403
vlan:
mode: trunk
trunk-tags:
- id: 20
ovn:
bridge-mappings:
- localnet: tenantblue
bridge: br-withvlan
state: present
2) Create localnetwork: tenantblue with networkAttachmentDefinition and set: forklift.konveyor.io/route: "192.168.20.1"
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
name: tenantblue
namespace: test
annotations:
forklift.konveyor.io/route: 192.168.20.1
spec:
config: |2
{
"cniVersion": "0.4.0",
"name": "tenantblue",
"type": "ovn-k8s-cni-overlay",
"topology":"localnet",
"subnets": "192.168.20.0/24",
"excludeSubnets": "192.168.20.1/32",
"vlanID": 20,
"netAttachDefName": "test/tenantblue"
}
3) Create cold migration plan: cold-ovn-br-vlan to migrate vm: mtv-rhel7-9-staticic from vSphere7, select the "Transfer Network: test/tenantblue"
4) Check the ImageConversion phase failed
5) Check the conversion pod cold-ovn-br-vlan-vm-275-9c9f5 log, more details in attached file: cold-ovn-br-vlan-vm-275-9c9f5-virt-v2v.log

6) Copy the plan to copy-of-cold-ovn-br-vlan without any change, execute the new plan successfully
7) Create a new pod with attached file: POD1-chhu.yaml, use test/tenantblue as default route, login to pod immediately after creating the pod, ping gateway failed, wait for a while in vm, ping gateway successfully

Actual results:
In step4,5: Migration plan failed in step4, rerun the plan successfully without any change In step6: Failed to ping outside in VM when the pod is created, wait for a while, can ping outside successfully
Expected results:
In step4, Migration plan executed successfully
