Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

The Linux USB passthrough device has been rewritten upstream. The old code is still around as device usb-host-linux, to simplify regression testing. Upstream is expected to drop it in a release or two.
While we might want to keep usb-host-linux enabled for beta to help trouble-shooting any issues popping up, we definitely don't want it enabled in GA.
How reproducible:
Always
Steps to Reproduce:
1. qemu-kvm -nodefaults -display none -monitor stdio -S -usb -device usb-host-linux
Actual results:
-device usb-host-linux is accepted
Expected results:
-device usb-host-linux is rejected, just like -device nonexistant
Verified on qemu-kvm-1.5.3-19.el7.x86_64:
# /usr/libexec/qemu-kvm -nodefaults -display none -monitor stdio -S -usb -device usb-host-linux
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) qemu-kvm: -device usb-host-linux: Parameter 'driver' expects device type
# /usr/libexec/qemu-kvm -device help 2>&1 | grep usb
