Hello Erlon, or anyone else affected,
Accepted ovn into hirsute-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/ovn/20.12.0-0ubuntu3
in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
hirsute to verification-done-hirsute. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-hirsute. In either case, without details of your
testing we will not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!
N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
Duplicated ARP responses from ovnmetadata namespaces
Status in networking-ovn:
Invalid
Status in ovn package in Ubuntu:
Fix Released
Status in ovn source package in Focal:
Incomplete
Status in ovn source package in Hirsute:
Fix Committed
Status in ovn source package in Impish:
Fix Released
Bug description:
When OpenStack instances are connected to an external network, an ovn-etadata-namespace is created in each compute that has VMs attached to that
network. Because the ovn-metadata namespace has interfaces with the same mac address in all computers, external switches might ARP query for the IP
and receive multiple responses in different ports triggering network error alerts.
