I already experienced this problem on Debian Etch with backported Xen/Libvirt/Virt-manager and this problem is a Libvirt 0.4.0 specific bug. Upgrade to Libvirt 0.4.1 or 0.4.2 will correct this problem.

Comment 1 Edward Clay 2008-07-02 16:53:33 UTC

I have run into the same problem. How do I get the newer code?

Comment 2 Léonard Laurent 2008-07-02 17:43:55 UTC

The Libvirt sources are available here : http://libvirt.org/sources The latest stable release seems to be the 0.4.4. 

It could be also great if the last version of Virt-manager (0.5.4, released march 10th, 2008) should be included in OpenSUSE 11.0 (instead of the 0.5.3)... The sources can be found here : http://virt-manager.org/download.html

Comment 3 Léonard Laurent 2008-07-03 22:10:53 UTC

The home:syntron/openSUSE_11.0 repository (http://download.opensuse.org/repositories/home:/syntron/openSUSE_11.0) seems to contain Libvirt 0.4.4 but when I try to install it I get the following error message : "nothing provides libgnutls.so.13()(64bit) needed by libvirt-0.4.4-12.1.x86_64".

Comment 4 Léonard Laurent 2008-07-03 22:27:18 UTC

I downgraded Libvirt to 0.3.0-30.5 (the last update from OpenSUSE 10.3) and Virt-manager seems to run successfully. So I can confirm the problem comes from Libvirt 0.4.0.

Comment 5 Doug Merrill 2008-07-03 23:44:01 UTC

Yes, we have isolated the offending call in libvirt and we'll be looking at it next week.

See bug #398932 for more details...

Removing "resolved duplicate" because duplicate bug is internal.

Comment 7 Doug Merrill 2008-07-03 23:47:37 UTC

Reopening bug.
