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:
Create this bug to track the virtio-input related testing, currently the following devices shows up in the qemu-kvm device lists:
name "virtio-input-host-device", bus virtio-bus
name "virtio-input-host-pci", bus PCI
name "virtio-keyboard-device", bus virtio-bus
name "virtio-keyboard-pci", bus PCI
name "virtio-mouse-device", bus virtio-bus
name "virtio-mouse-pci", bus PCI
name "virtio-tablet-device", bus virtio-bus
name "virtio-tablet-pci", bus PCI
Please developer help adjust or fix something if they are not accurate.

Additional info:
I've checked they work with our qemu version:
name "virtio-keyboard-device", bus virtio-bus
name "virtio-keyboard-pci", bus PCI
name "virtio-mouse-device", bus virtio-bus
name "virtio-mouse-pci", bus PCI
They work fine.
I have tested them on text console and using gpm to test the mouse.
I've also checked them with Fedora 23 graphical installer and they work fine too, + the tablet device:
name "virtio-tablet-device", bus virtio-bus
name "virtio-tablet-pci", bus PCI
I'm not able to confirm "input-host" works as I have no physical access to a host.
Just got Gerd's reply , we can skip the virtio-input-host-pci test on ppc.

Just skip the test on ppc then.

Guess you mean Bug 1248933, actually we test on qemu-kvm-rhev-2.6.0-8.el7.ppc64le, see detail on 1248933#c10.

No, I mean: how virtio-input-host was tested for qemu-kvm-rhev-2.3.0?
But the code involved in virtio-input-host is only ~200 lines, so as Gerd has proposed, I think it is acceptable to only test this on x86_64 (as communication with host is done using generic ioctls through the event interface).
And I think user will have the same problematic we have: no physical access to the server.
So, just skip the test on ppc64le.

I'll test BE guest and update result.

virtio-input not be tested for qemu-kvm-rhev-2.3.0
