This is not really useful as -private files will never be included from
libvirt-gconfig.h, just drop it (and we'll have to fix
libvirt-gconfig-helpers-private.h  as well). For what it's worth, for the
device/... _new_from_tree methods I've been lazy and I've grouped them in
the same -private file, but I'm fine with a separate file per class.

I've spelt 3 letter acronyms "Xml" instead of XML when using camel case
spelling, I'd rather use Cpu instead of cpu here too

This "if" is needed because we can have <features><foo/></features> VS
<feature name="foo">? This deserves a comment explaining why we do this
test. Having a per-feature GVirConfigObject seems overkill since it will
only be a string wrapper, and a GVirConfigObject wrapping just a string
with no node name identifying the type of the node is unusual.
Not having this class, and doing the parsing directly from
gvir_config_capabilities_cpu_get_features would allow to remove it.

GVirConfigDomain can also have a <features> node, the strings mentioned
above can be wrapped in a GVirConfigCpuFeatures object (or just a typedef?)
instead of in a raw GList, and then we can factor the GVirConfigDomain and
GVirConfigCapabilitiesCpu code somehow.

I don't think many _new_from_tree functions are currently doing that, but
I'd add a
 g_return_val_if_fail(!GVIR_CONFIG_IS_XML_DOC(doc), NULL);
 g_return_val_if_fail(g_strcmp0(tree->name, "cpu") == 0, NULL);

Is it expected that "features" nodes are ignored? Are the 2 kind of nodes
(feature/features) two different things that we want to expose differently
in the API?

Is it a mandatory element in the capabilities XML? If not, a
if (node == NULL) {
    return NULL;
}
is better

This is the same code as gvir_config_capabilities_host_get_cpu, if this
pattern gets repeated often, it will be worth trying to factor it in a
helper function.
