Comment 4 for bug 1311870

To boot pv domUs with newer grub pvgrub2 is needed, I'm using for a few months a custom build from source, Trusty have it in official repository: http://packages.ubuntu.com/trusty/grub-xen
Even if I not tested official debian/ubuntu now and from a quick look I do not saw where is the file to pass to the domU's configuration as kernel to use it.

Can someone tell how to use it and add a documentation?
