Bug 494749

This was brought up on the mailing list. My response there was:

The version of libvirt on your machine lacks the openAuth command, so we
are falling back to read-only mode. We could try to detect this and just
try the plain 'open' command instead.

That said, if you are using virt-manager 0.7.0 on centos, you should
probably update libvirt beyond the stock centos version as well, since
that is where most of the features come from.

I affirm that I too am reproduceably unable to connect top a completely stock CentOS 5.3 x86_64 dom0 instance, using virt-manager and the following packages:

As the original reporter has added non-stock items, I confirm his initial reporting issue against a stock 5.3 install.  Please advise if this needs to be cloned.  I see it is being carried against "Virtualization Tools 4.4", and the subject line mentions: "virt-manager 0.7.0", although his report also mentions virt-manager-0.5.3-10.el5  as the installed environment

There seems to be some missing dbus files, per strace:

I run it thru the following cleanup to clear the dbus rpm -V errors:

 1012  Apr 15 12:21 sudo rpm -e dbus --allmatches --nodeps
 1013  Apr 15 12:22 sudo rm -rf  /etc/dbus-1/session.conf /etc/dbus-1/system.conf /etc/rc.d/init.d/messagebus
 1014  Apr 15 12:22 sudo yum -y install dbus

As the dbus removal sometimes runs through a %pre or %post scripts error, I add this in some reproducers:

[herrold@centos-5 ~]$ sudo rpm -e dbus --allmatches --nodeps --noscripts

and follow it with relabel and reboot to remove SELinux state issues from the mix:

[herrold@centos-5 rc.d]$ sudo touch /.autorelabel

This shouldn't be an issue anymore with current upstream, I believe. Closing as UPSTREAM.
