It will only work if someone interested enough submits patches.

Here, I wonder if we can't improve the situation;
src/util/virutil.c:virSetInherit() does nothing, and its wrapper
virSetCloseExec() should therefore always return 0, which makes it very
suspicious - the message in src/rpc/virnetsocket.c about close-on-exec
not working should never be reached.

What version of virsh is included in that msi?  Maybe it's just a case
of a stale build, for something that has been fixed upstream?

But I personally have not tried to build or debug on mingw, to know if
this is the only issue, or if you are staring at a number of other
portability issues to resolve first.
