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 Richard W.M. Jones 2011-06-02 10:45:14 UTC
Description of problem:

When qemu-kvm runs, it prints an unnecessary warning, eg:

  # virt-df -h
  Filesystem                        Size    Used  Available  Use%
* Using CPU model "cpu64-rhel6"
  builder_debian:/dev/sda1          9.4G    3.3G       5.6G   36%
  builder_ubuntu:/dev/sda1           15G    5.0G       9.3G   33%
  [etc]

Version-Release number of selected component (if applicable):

qemu-kvm-0.12.1.2-2.160.el6.x86_64

Comment 2 Richard W.M. Jones 2011-06-02 11:08:52 UTC
Created attachment 502500 [details]
qemu-kvm-no-using-cpu-model-message.patch

This simple patch removes the fprintf statement.  With
this patch, the code in that function now matches what
is in upstream qemu.

Comment 5 Richard W.M. Jones 2011-06-03 08:34:29 UTC
QA for this:

(1) On a RHEL 6.2 host that has >= 1 libvirt guest,

(2) install updated qemu-kvm, and libguestfs-tools packages.

(3) Run this command as root:

# virt-df

The string "Using CPU model" should not appear anywhere
in the output.

Comment 9 Shaolong Hu 2011-09-28 08:01:23 UTC
Reproduced on qemu-kvm-0.12.1.2-2.160.el6.x86_64:

Steps and results:
------------------
[root@localhost ~]# /usr/libexec/qemu-kvm
Using CPU model "cpu64-rhel6"
VNC server running on `::1:5902'


Verified on qemu-kvm-0.12.1.2-2.192.el6.x86_64:

Steps and results:
------------------
[root@localhost ~]# /usr/libexec/qemu-kvm
VNC server running on `::1:5901'



Based on above results, fixed.
