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.

2. Create podman network using mcvlan driver

~~~
# podman  network ls
NETWORK ID    NAME        DRIVER
119db1ac0481  mcv0        macvlan
2f259bab93aa  podman      bridge
# podman network inspect mcv0
[
     {
          "name": "mcv0",
          "id": "119db1ac0481bd402c37c82717555604dc1df23b42ba268d52e7fc7f2a418027",
          "driver": "macvlan",
          "network_interface": "ens192",
          "created": "2022-11-14T19:28:57.518598198+05:30",
          "subnets": [
               {
                    "subnet": "10.74.128.0/22",
                    "gateway": "10.74.131.254"
               }
          ],
          "ipv6_enabled": false,
          "internal": false,
          "dns_enabled": true,
          "options": {
               "mode": "bridge"
          },
          "ipam_options": {
               "driver": "host-local"
          }
     }
]
~~~

3. Run podman using MAC option to use static MAC

~~~
# podman run --network mcv0 -it  --mac-address=66:99:8f:19:2e:74 --rm --name test1_bridge quay.io/rhn_support_kmarutha/ubi8custom ip a s|grep -A2 eth0
8: eth0@if2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether da:36:f2:83:74:45 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 10.74.128.1/22 brd 10.74.131.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::d836:f2ff:fe83:7445/64 scope link tentative
~~~

Actual results:

~~~
# podman run --network mcv0 -it  --mac-address=66:99:8f:19:2e:74 --rm --name test1_bridge quay.io/rhn_support_kmarutha/ubi8custom ip a s|grep -A2 eth0
8: eth0@if2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether da:36:f2:83:74:45 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 10.74.128.1/22 brd 10.74.131.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::d836:f2ff:fe83:7445/64 scope link tentative
~~~

Expected results:

MAC address should be static as it mentioned --mac-address=66:99:8f:19:2e:74.

Additional info:

It is working in podman with cni as backend network using mcvlan driver.

~~~
# podman info |grep -i network
  networkBackend: cni
  network:

# podman run --network mcv0 -it  --mac-address=66:99:8f:19:2e:74 --rm --name test1_bridge quay.io/rhn_support_kmarutha/ubi8custom ip a s|grep -A2 eth0

Comment 3 Brent Baude 2022-11-21 18:13:10 UTC 
This bug was fixed upstream and released in netavark-v1.2.  Because no version of netavark was provided in this bug,  I cannot comment further.

Comment 8 Joy Pu 2022-12-05 10:23:27 UTC 
Can reproduce with netavark-1.0.1-39.module+el8.6.0+16891+aaa3bd4c.x86_64.rpm. Test with netavark-1.3.0-1.module+el8.8.0+17233+49402d35.x86_64 and it works as expected now. The Mac addr is already the same as command line. So move it to verified:
# podman network create -d macvlan -o parent=ens3 --subnet="10.74.128.0/22" --gateway="10.74.131.254" mcv0 
mcv0
