Indeed. The existing host capabilities XML gives a reasonable amount
of data on the core hypervisor features. We need equivalent data that
covers device emulation features. This will quite dramatically expand
the amount of capability data, since there are soooo many combinations.
Figuring out the correct available options will be fun too, but clearly
we need to adress this at some point. We only get away with it now
because both Xen and KVM are both reasonably similar in device capabilities
via the shared QEMU base. If we ever get a VMWare driver for libvirt
there will be dramatically different device emulation features to worry
