Increase in the full path to mkfs.xfs(/sbin/mkfs.xfs).

Xfsprogs package has been installed. This is the cause of the error stack does not have
permission to perform mkfs.xfs command rather mkfs.xfs command in /sbin/
path, stack in order to perform mkfs.xfs must add the full path or use
the sudo command mode.

Install qemu-kvm instead of kvm package on Ubuntu

Since at least 12.04, the kvm package is a transitional dummy
package intended to move users to the newer qemu-kvm package.  This
removes the dependency on this dummy package, which will be going away
in 14.04, and instead depends on the proper qemu-kvm package.
