Hi Chris,

Thanks for the interest -- so: ok, for you to take a look and to
enable testing by anyone who would like to: I've just pushed a copy of
the Argo ported Linux driver and userspace interposer, etc., with some
OpenEmbedded build integration and instructions, to my github account
here:

https://github.com/dozylynx/meta-argo-linux

This a pretty fast port of the v4v Linux software to use the argo
interfaces -- the existing OpenXT v4v interface is not quite the same
-- plus metadata in there to turn it into a new OpenEmbedded layer in
the same repo with recipes to work with meta-virtualization. I've been
building with the rocko release, just to pick a stable reference
point, so it's the rocko branch in meta-argo-linux that you'll want to
look at, and there are instructions in the README.md in that branch.

If you build that per the instructions, just a heads up that the Xen
recipe in there will pull from a recent snapshot of Xen's staging
branch, with the posted Argo series applied, from a copy on my github
account.

If you give it a spin, let me know how it goes.

thanks,

Christopher
