+Currently, virt-v2v has no way to set the default kernel in Debian

+virt-v2v will not change the default kernel used for booting, even

Make the documentation in Convert_linux more generic than just
Enterprise distros using RPM.  Also, rename the name of the module from
"enterprise-linux" to simply "linux".
