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:
KVM QE compared the list of cmd line and devices difference between rhel6.4 and rhel7.0. Found some general virtio devices are added. From KVM QE POV,  Plese disable or remove usb related devices that qemu-kvm does not support.

Version-Release number of selected component (if applicable):
Host Kernel
#uname -r
3.7.0-0.30.el7.x86_64
qemu-kvm version
qemu-kvm-1.3.0-3.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.
2.
3.
  
Actual results:
RHEL6.4
Virtio device
#/usr/libexec/qemu-kvm -device ? 2>&1 | grep -i virtio
name "virtio-scsi-pci", bus PCI, alias "virtio-scsi"
name "virtio-balloon-pci", bus PCI
name "virtio-serial-pci", bus PCI, alias "virtio-serial"
name "virtio-net-pci", bus PCI
name "virtio-blk-pci", bus PCI, alias "virtio-blk"
name "virtserialport", bus virtio-serial-bus
name "virtconsole", bus virtio-serial-bus

RHEL7.0
Virtio device(added virtio-rng-pci and virtio-9p-pci, will be supported on rhel7.0?)
#/usr/libexec/qemu-kvm -device ? 2>&1 | grep -i virtio
name "virtio-blk-pci", bus PCI, alias "virtio-blk"
name "virtio-9p-pci", bus PCI
name "virtserialport", bus virtio-serial-bus
name "virtconsole", bus virtio-serial-bus
name "virtio-serial-pci", bus PCI, alias "virtio-serial"
name "virtio-rng-pci", bus PCI
name "virtio-net-pci", bus PCI, alias "virtio-net"
name "virtio-scsi-pci", bus PCI
name "virtio-balloon-pci", bus PCI, alias "virtio-balloon"

Expected results:
Disable or remove general virtio devices that qemu-kvm does not support

Comment 1 Richard W.M. Jones 2013-01-29 08:34:36 UTC
virtio-rng-pci should definitely be in RHEL 7.  It's a
very useful device.

virtio-9p-pci is also useful -- libguestfs *could* use it (although
not by default), and I believe that Dan's libvirt sandbox stuff
is based on it.  However 9pfs hasn't exactly set the world on fire.

Reproduced this issue using qemu-kvm-1.3.0-6.el7.x86_64, "virtio-9p-pci" is not removed.
# /usr/libexec/qemu-kvm -device ? 2>&1 | grep -i virtio
name "virtio-blk-pci", bus PCI, alias "virtio-blk"
name "virtio-9p-pci", bus PCI
name "virtserialport", bus virtio-serial-bus
name "virtconsole", bus virtio-serial-bus
name "virtio-serial-pci", bus PCI, alias "virtio-serial"

name "virtio-net-pci", bus PCI, alias "virtio-net"
name "virtio-scsi-pci", bus PCI
