Description of problem:

No network connectivity after installing vSphere UPI with static IP kargs bonding


Version-Release number of selected component (if applicable):

4.11.0-0.nightly-2022-05-25-193227


How reproducible:

Always

Steps to Reproduce:
1. install with static IP kargs bonding

guestinfo.afterburn.initrd.network-kargs:
ip=172.31.248.7::172.31.248.1:255.255.254.0:rbrattai-o411vb22-cczb8-control-plane-1:bond0:none nameserver=10.3.192.12 bond=bond0:ens192,ens224:mode=active-backup,miimon=100


Actual results:

Install fails, no networking connectivity on node.

Expected results:

Install succeeds.

Additional info:


Last successful install with the same parameters was with 4.10.0-0.nightly-2022-04-06-195507

Comment 2 Ross Brattain 2022-06-17 00:50:46 UTC

Unable to reproduce with https://github.com/openshift/machine-config-operator/pull/3190   4.11.0-0.ci.test-2022-06-16-162452-ci-ln-106kkgt-latest

Could it be the bonding fixes?  Removing `connection.autoconnect-slaves 1` or setting the `ovs-if-phys` MAC?

Comment 3 Ross Brattain 2022-06-17 01:02:41 UTC

Looks like the bond0 MAC != the br-ex MAC in the failure logs.

With https://github.com/openshift/machine-config-operator/pull/3190

bond0 MAC == br-ex MAC.
