Yes. Fixed in the new packages.

You could have just removed xen-linux-system-* as it is only a meta

Yes. I removed that warning now as it makes more grief than good and is
not included in the paravirt_ops implementation.

This is the result of a bug in libc6-xen, set the following in
/etc/ld.so.conf.d/lib6-xen.conf
| hwcap 1 nosegneg
and run ldconfig. See #499366.

I would appriciate any possible testing.
