Hi, I _guess_, the problem is due to an unfortunate mixture of gdk-pixbuf paths. In the first alpha-release gtk2 would expect gdk-pixbuf loaders in /etc/gtk-2.0/[i386|x86_64]-koji-linux-gnu/gdk-pixbuf.loaders. the current release uses /etc/gtk-2.0/x86_64-redhat-linux-gnu/gdk-pixbuf.loaders (makes sense), but librsvg2 still uses the koji-path: rpm -qp librsvg2-2.26.0-5.el6.x86_64.rpm --scripts /usr/bin/update-gdk-pixbuf-loaders x86_64-koji-linux-gnu || : It's just a guess, but I could imagine it confusing gtk sufficiently not to recognize svg's ...

I figure it's probably a matter of installation order. And I seem to remember it's not the first time the gdk-pixbuf stuff is causing this kind of problem :-( > > Maybe someone should tell them that rpm now has triggers :-> > > Except for this problem, virtualization works well. I successfully installed SL6 xen paravirt VMs (64- and 32-bit) on an SL5 xen host (64-bit), SL6 VMs on an SL6 KVM host (64/64), and SL5.5 VMs on an SL6 KVM host (also 64/64), using virt-install and raw LVM volumes on direct attached storage as the backend. I haven't compared the performance to Xen yet, but it works without problems. > > Thanks again, > Stephan > >> or just comment out lines 343,344 in /usr/share/virt-manager/virt-manager.py to allow virt-manager to start . >> " >> I haven't tested this, but they were getting the same errors you were getting. >> >> Troy >
