Seems that libvirt snapshots are not working correctly with
2.0~git-20140307.4c288ac-0ubuntu2. Eg:

$ virsh snapshot-create-as test-saucy-amd64 pristine "uvt snapshot"
error: internal error: Child process (/usr/bin/kvm-img snapshot -c pristine
/home/jamie/vms/machines/test-saucy-amd64.qcow2) unexpected exit status 1:
libvirt:  error : cannot execute binary /usr/bin/kvm-img: No such file or directory

/usr/bin/kvm-img used to be part of qemu-utils, but
2.0~git-20140307.4c288ac-0ubuntu2 doesn't ship it.

Creating a symlink to /usr/bin/qemu-img from /usr/bin/kvm-img makes this error
go away and things seem to work, but I've not reviewed/tested if this is the
correct fix.
