In order to apply dynamically generated virt-type config to the actual templates they need to be rendered. Also improves a KVM presence check since the CPU features may be visible to a container but KVM API via a character file might not be available there. The cpu-mode is now also set to "host-model" instead of "host-passthrough" when emulation is used as it is done in the default config.
