Re: [PATCH 18/18] qemu: Default to no USB and no memballoon for new architectures

The current defaults, that can be altered on a per-architecture basis, are derived by the historical x86 behavior. Every time support for a new architecture is added to libvirt, care must be taken to override these default: if that doesn't happen, all guests will end up with additional hardware which is generally not wanted. Turn things around, and require architectures to explicitly ask for the devices to be created by default instead. The behavior for existing architectures is preserved.
