Comment 7 for bug 1297224

So we talk about different sides. Debian has not, yet packaged up Xen-4.4 (there was a post to Debian today asking how we can change that), I did package Xen-4.4 for Ubuntu Trusty (14.04). That does a lot of the things you were suggesting. Maybe not all in a way that will be ok with Debian. I will try to work together with whoever does the Debian side (if that person wants me to).
Otherwise (if Debian would have been quicker in picking up 4.4) normally Ubuntu picks the Debian version and I would try to keep the differences at a minimum. But sometimes there is no way around doing some things different.
