Description Jes Sorensen 2010-07-30 07:21:24 UTC
Description of problem:
Ran into a situation where a RHEL6 guest refused to run yum update. It
showed up that I somehow had gotten libvirt installed in the guest and it
was creating it's dnsmasq bridge on 192.168.122.0 blocking all traffic to
the host network.

Had to chkconfig libvirtd off + reboot to resolve it. ifconfig virbr0 in
the guest did not make the problem go away.

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Comment 3 Jiri Denemark 2010-07-30 10:04:08 UTC
What version of libvirt did you installed in the guest? This bug is supposed to be fixed in libvirt-0.8.1-8.el6 (see bug 594494).

Comment 4 Jes Sorensen 2010-07-30 10:10:15 UTC
Hi,

Sorry I didn't record the version that was installed at the time, I
worked around it as described and of course that changed the installed
version. I am pretty sure it was whatever was in beta2, but if you believe
it is fixed in upstream, feel free to close the bug.

Cheers,
Jes

Comment 5 Jes Sorensen 2010-07-30 10:37:20 UTC
Tested the version that was installed with the update: 0.8.1-20 and the
problem is fixed in there.
