Re: [libvirt] [PATCH V4 0/3] Parser for xen-xl config format

It's been a long, twisting road to V4 of the Xen xl parser. V3 [1] was based on a flex-based parser that was copied from the Xen project and proved to be a bit challenging to integrate properly with autotools. But as it turns out, Xen provides an interface to the parser via libxlutil. I hadn't realized this interface was available for external consumption since the corresponding header file was never installed. Patch sent to xen-devel [2] to install the header, but in the meantime need to declare gthe imported libxlutil functions as extern (see patch 1). V4 uses libxlutil, which has simplified the series quite a bit and eliminates the potential of the copied flex parser diverging from the canonical source in xen.git.
