Ensure the full version of virt-v2v and virt-p2v is available in the
conversion log file, the only log file that we reliably get from users
and customers. "Full version" means the major, minor, release and
extra fields. The extra field is especially important as it contains
the downstream package release in Fedora, RHEL etc.
This change saves the virt-p2v version as a comment in the
physical.xml file, which is included in full in the conversion log (by
virt-v2v).
It also ensures that the initial virt-v2v debug message contains the
full version number including the 'extra' field.
$ cat virt-v2v-conversion-log.txt
virt-v2v: libguestfs 1.37.7local,libvirt (x86_64)
...
<!-- virt-p2v 1.37.7local,libvirt -->
It also adds 'p2v-version' and 'v2v-version' files in the virt-p2v
debug directory. These are strictly superfluous but could be useful
for end users.
$ cat p2v-version
virt-p2v 1.37.7local,libvirt
$ cat v2v-version
virt-v2v 1.37.7local,libvirt
