  Well that's really cool. I assume what you get in the end is the library
with just the remote support, but which should be sufficient to connect to
the boxes hosting the hypervisors and libvirt daemon, right ?

  Hum, also one of the problem i found out quickly with libxml2 on windows
is that most people just can use cygwin, some just fallback to mingw for 
licencing issues but a large majority use some kind of Microsoft compilers,
and getting a DLL which works with more than one can be seriously challenging.

  If the goal is to get virt-manager working, then yes cygwin should be just
fine once the shared lib issue is fixed. I assume virsh remote support works
now, right ?

  Ouch, that's not really something we can embbed generally ...
