FWIW, I'm able to create new unattended Fedora 20 VMs just fine with a
script like that[1] which uses virt-install. To invoke the script:

    $ ./create-guest-qcow2.bash f20vm1 f20 x86_64


Or you can try trivially install guests with a tool like virt-builder.
To install a Fedora 20 guest and update to latest available packages:

    $ virt-builder fedora-20 -o f20vm1.qcow2 --update --selinux-relabel \
      --format qcow2 --size 30G

Import the guest into libvirt:

   $ virt-install --name f20vm1 --ram 2048 --disk \
      path=/home/kashyap/f20vm1.qcow2,format=qcow2 --import
