Mozilla and Debian are hosted on Xen systems.

A tiny data point about these domains. They are hosted by,
which uses xen systems running with the current dom0 patch set. Because
those patches are out-of-tree, they have a hard time updating kernel
versions, and generally lag releases by a lot, which is not
always a good thing.

So getting the dom0 patches into mainline will make their lives much
easier, and more secure.

I know at least a couple of mid-sized hosting companies migrating all or part of their infrastructure off Linux/Xen to a proprietary solution, because of this very reason (problems with keeping dom0 kernel up to date, problems with deploying it on new machines etc.).
