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:

In the DPDK vhost-port (the counter part of vhost-user), add support 
for virtio-1


How reproducible:

Bring the Qemu guest up with disable-legacy=on, disable-modern=off and check for proper operation

This is a requirement for efficient use of VFIO with Virtio devices, since it allows memory mapped operation removing the need for system calls.
Virtio-0 uses only port-IO (no memory IO).

Upstream commits:
 - commit 15e9ee6982a4822ce395fd597dd500a61ceafa7c (vhost: enable virtio 1.0)
 - commit 45c55d39c5ebb8f8e1e70401dd0492f6c935455b (vhost: fix build with old kernels)

Thanks,
Marcel
