It's not clear to me what I should do with this attribute. On
Xen/unstable, it contains the single value "xen,xen-4.5", meaning (I
think) that Xen 4.5 is incompatible with Xen 4.4. But I'd still like
Mini-OS to run. Presumably, 4.6 will be incompatible too. What could I
do if the value doesn't match except try to use it anyway?
