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.

Hi Maxime, is there any feedback from Nova on this proposal?

Comment 3 Maxime Coquelin 2017-08-31 12:53:32 UTC
Hi Kevin, No feedback from Nova so far.

Comment 4 Kevin Traynor 2018-02-07 12:23:21 UTC
There is some vhost-user information now available as of this commit in OVS 2.9

AFAIK, due to upstream wanting to also migrate between kernel space vhost and vhost-user, some more design is needed in other layers. There is no outstanding requests to openvswitch atm.

Comment 5 Kevin Traynor 2018-05-25 14:38:30 UTC
Hi Maxime, do you know the status of the proposal? Is anything needed from openvswitch or can we close this Bz? We can re-open if something is needed in future.

Comment 6 Kevin Traynor 2018-06-15 13:30:10 UTC
Maxime and I discussed on irc. The proposals have changed and nothing needed from OVS now and it's not envisaged there will be.
