Thanks Daniel for suggestion, i have made changes in my xml script.
I am able to set up lxc container on fedora 18
i created a container using yum
yum --installroot=/containers/cont1 --releasever=18 install -y httpd
openssh, bridge-utils, dhclient
cont1.xml

....snip more <filesystem> elements...
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.
