Running the latest commit in the libvirt.git:master branch is the latest
version.  We don't go to any effort to give it a different version
number, though, so the built product will match the latest release
(currently 1.0.2).  Perhaps we could tweak things so that when built
from git, 'virsh --version' would report the git version that was used
to build things, but so far, that hasn't been on anyone's high-priority
list.  It is generally assumed that if you are competent enough to be
building directly from latest git, then you are also competent to know
how to use 'git describe' to tell what commit you are building.
