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.
