When i create a vm on this host with architecture ppc, the template says "Machine Type: kvm / x86_64"

Sorry, what template are you talking about here precisely?

The properties when you click on the create VM under the compute resource

This is probably a bug in fog-libvirt, it isn't populating the 'arch' attribute when retrieving the list of domains so it's falling back to the default that the fog-libvirt model defines (x86_64). (Assuming the arch is even supplied by libvirt.)
