Why does Red Hat Enterprise Linux 7.2 anaconda fail to stat the kickstart downloaded from NFS source ?

Issue

• Need to install Red Hat Enterprise Linux 7.2 using Kickstart file hosted on NFS server.
• The command to create a virtual machine is as follows.

#  virt-install    --name=test    --graphics vnc    --vcpus=6 --ram=4096    --disk path=/images/tesst.img,bus=virtio,size=20,format=qcow2,sparse=true    --location=nfs:192.168.122.1:/images/install7.2    --extra-args="ks=nfs:192.168.122.1:/images/install7.2/ks_test.cfg lang=en_US keymap=us"    --network bridge=virbr0,model=virtio    --os-type=linux    --os-variant=rhel7    --virt-type kvm    --hvm    --noreboot

• The kickstart is downloaded but fails to get read by anaconda as follows.

[   11.227525] dracut-initqueue[536]: cp: cannot stat '/run/install/repo/ks_test.cfg/ks_test.cfg': Not a directory
[   11.228573] dracut-initqueue[536]: Warning: failed to fetch kickstart from nfs:192.168.122.1:/images/install7.2/ks_test.cfg 

• Is it a bug?
