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 of problem:

It has been observed that implementation of TX queue size is not implemented in correct way in nova/libvirt/qemu i.e.

setting tx_queue_size in nova.conf doesn't propagate to guest VM correctly and also it does not translate to set the txqueuelen param value of tap interfaces.

It is part of the proposed solutions discussed in 
BZ- https://bugzilla.redhat.com/show_bug.cgi?id=2007572

So, this RFE is to track the implementation of tuned profile to support the tuning of txqueuelen parameter.

*** Bug 2007572 has been marked as a duplicate of this bug. ***

At the moment TuneD supports setting of the HW NIC queues (those controlled by the ethtool), but not the upper level txqueuelen. I think we could add support for it to the 'net' plugin.

I also changed the component to the 'tuned'.
