[Pkg-libvirt-maintainers] Bug#655460: misleading error message on missing br0 interface

[Harald Dunkel]

Package: virtinst
Version: 0.600.0-1

I missed to define a local "br0" network interface on my new KVM
server. When I tried to create a new machine using an existing
host.xml file listing "br0" as a network interface I got an
error message about an inaccessible disk image instead.

# export VIRSH_DEFAULT_CONNECT_URI=qemu:///system
# masterhost=dpcl082
# master=openSUSE-11.3-i386-template
# name=sepos11i004
# virsh vol-create-as storage ${name}.vda.lv 32G
# ssh ${masterhost} dd if=/dev/storage/${master}.vda.lv bs=64k | dd bs=64k of=/dev/storage/${name}.vda.lv
# virt-clone --connect ${VIRSH_DEFAULT_CONNECT_URI} --original-xml=/tmp/${master}.xml --name=${name} --file=/dev/storage/${name}.vda.lv --preserve-data
ERROR    Could not determine original disk information: Size must be specified for non existent volume path '/dev/storage/openSUSE-11.3-i386-template.vda.lv'


After setting up the br0 interface the error message about
the disk was gone, so there is something weird.

Debug output:
