RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Quique Llorente 2023-03-28 17:00:23 UTC 
Description of problem:

Openshift uses the ovs-configuration script to setup the br-ex ovs-interface, this interface do a mac cloning from the primary interface and activates dhcp to take over the address, but looks like the DHCP is not send when  br-ex is activated.

The script also do a rollback to remove this configuration and this rollback is able to send the DHCP

How reproducible: Always


Steps to Reproduce:
1. Start a hypershift cluster with kubevirt provider
2. Run the hypershift e2e test
export OCP_IMAGE_LATEST=registry.ci.openshift.org/ocp/release:4.13.0-0.nightly-2023-03-23-204038
export OCP_IMAGE_PREVIOUS=registry.ci.openshift.org/ocp/release:4.13.0-0.nightly-2023-03-23-204038
bin/test-e2e \
        --test.v \
        --test.timeout=0 \
        --test.run='^TestCreateCluster$' \
        --e2e.node-pool-replicas=1 \
        --e2e.kubevirt-node-memory="6Gi" \
        --e2e.platform="KubeVirt" \
	--e2e.latest-release-image=${OCP_IMAGE_LATEST} \
	--e2e.previous-release-image=${OCP_IMAGE_PREVIOUS} \
	--e2e.pull-secret-file=/home/dvossel/pull-secret-file.txt
3.

Actual results:
The VM that is the worker is not ready since the br-ex ovs interface never receive the ip config from DHCP server at virt-launcher

journal show that NM tries to send a DHCP discover but it never get a lease for it

So we end up with

Expected results:
The ip config should be received


Additional info:

This is OCP 4.13 based cluster

We also see that "Network manager dispatcher service" and "hostname service" are started in the middle of "ovs-configuration" br-ex retries.

Comment 4 Beniamino Galvani 2023-03-29 08:19:26 UTC 
The packet capture looks weird. First, while the log indicates that NM is sending multiple DHCP DISCOVERs, the capture only has a REQUEST followed by an ACK and then many REQUESTs again. Also, all the REQUESTs appear very close to each other and they look identical. One possible explanation could be that there is a loop in the network topology which creates a packet storm.

Can you please investigate this, and perhaps also do a packet capture on enp1s0 on the client machine to see what NM is sending?

Those DHCP messages are from the beggining and end of the ovs-configuration script, the flow is like this
1 - enp1s0 is configured
2 - DHCP DISCOVER/REQUEST is received
3 - br-ex ovs-interface is created cloning the enp1s0 mac address
4 - nmcli con up br-ex is retried 10 times (NetworkManager waits 45 seconds each)
5 - DHCP is not received
6 - ovs-configuration do a "rollback" and remove the ovs artifacts and set enp1s0 up
7 - DHCP DISCOVER/REQUEST is received

What you see there is the DHCP from 1 and 5

We are preparing and env to investigate
Comment 6 Quique Llorente 2023-03-29 19:05:26 UTC 
@bgalvani we have manage to capture from the node primary interface although is different deployment so mac addresses and ip will not match with journal attached.

We see the expected behaviour

This is at first boot before br-ex take over

Then we have "nmcli con up ovs-if-br-ex" trying to take over it but there is no DHCP request at all

<EMPTY>

After that is the "rollback process" where the primary interace is removed from ovs-bridge and re-configured then we see expected DHCP

Comment 7 Quique Llorente 2023-03-29 19:09:31 UTC 
Also I have see that we have a NM dispatcher scritp related ovs I don't know if it can be related

/etc/NetworkManager/dispatcher.d/pre-up.d/10-ofport-request.sh
#!/bin/bash
# Set interface ofport_request to guarantee stable ofport numbers. This is important for flow matches.
# Otherwise, another ofport number is assigned to the interface on every restart of NetworkManager.
# This script will build an associative array INTERFACE_NAME->ofport_request and will save it to file CONFIGURATION_FILE.
# When an interface is brought up, this will reuse the value from the associative array if such a value exists.
# Otherwise, this will try to use the current ofport value. If the ofport value is already reserved, then
# this uses the lowest available numerical value, instead.


This is the full dispatchers list

> <EMPTY>

Ok, this means that the requests are not forwarded from br-ex to the physical interface. From the log attached it seems that all interfaces are configured properly, but to double-check, is it possible for you to show the output of these commands when DHCP is running?

 ip addr
 ovs-vsctl show

Also, please try to remove the `10-ofport-request.sh` dispatcher script to see if that makes any difference.

Comment 12 Quique Llorente 2023-03-30 15:25:22 UTC

Looks like br-ex is sending the DHCP request but it's not traversiong the ovs-bridge and it's not re-transmited to enp1s0
