I recently updated for libvirt 0.4.6 to libvirt 0.6.0. Now several of the virtual machines I defined, are not shown in virt-manager nor by virsh list --all, although the config files are still in /etc/libvirt/qemu. I tried to run virsh create, and this error is shown: libvir: Domain Config error : internal error os type 'hvm' & arch 'i686' combination is not supported This configuration was working perfectly with libvirt 0.4.6. I needed to change i686 to x86_64 in all config files of 32 bit systems to make them work again. Is there no way libvirt could migrate those configuration files automatically? -- Frederik Himpe -- Libvir-list mailing list Libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
