Alas, this will not work for XEN users because I can’t update the microcode in Dom0 with xen-hypervisor 4.1. There exist kernel patches (over a year old), but according to the xen-devel ML they are not good enough to be included in the kernel. With XEN 4.2 the hypervisor can load the CPU microcode. Would this be a reason to include XEN 4.2 in Wheezy?
