My point was about providing our own binaries for the oVirt guest agent. 
We have not yet solved targeting Windows for the guest agent binaries 
for oVirt. My bad that it wasn't explicit enough.

Well on fedora it would be as easy as yum install spice-vdagent, no 
headaches here from my point of view.
However requiring all the devel packages just to install the agent on 
the target platform from sources is a bit overkill in my opinion.
On linux we rather should go with the default packaging ways. That's 
what we're working on at the moment as well. We have already built 
packages for Fedora, distributions using EPEL (e.g. CentOS), OpenSUSE 
and Ubuntu. Upcoming targets are SLES and Debian.

So for those it would be doable without having to build from sources. 
However besides Fedora and EPEL we don't have yet reached inclusion into 
the repositories for those packages, for Ubuntu it's on launchpad and 
for OpenSuSE on their open build infrastructure.

As I said eventually we'll get there that we'll provide binaries for that.
