Permissions on /var/lib/libvirt/images/kfat.img? selinux?

I had this exact problem a while back and I am racking my brains as to what I did to fix it.

in my case,

# virt-install --network bridge:br0 --name kfat --ram=2048 --vcpus=2 \ --disk path=/var/lib/libvirt/images/kfat.img,size=16,cache=writeback \ --cdrom=/home/downloads/CentOS-6.5-x86_64-minimal.iso

worked.

the 'cache=writeback' fixed it, the fundamental problem was, /var/lib/libvirt/images is XFS on a SSD so is using 4096 byte sectors, and kvm has an impedance mismatch with that.
