Why are you adding all these sub-mounts for /var, /dev, etc, etc?
You installed the entire OS tree into /containers/test1, so it
should be sufficient to just have that first <filesystem>
entry for '/'. You'd only want to add extra mounts for
/var, etc if the directory on the host came from somewhere
outside the /containers/test1 location.
NB, also libvirt sets up /dev - you shouldn't try to
override it, or you'll loose access to the pre-populate
device nodes, which is probably what's causing your
failure.
