To allow compatibility with older QEMU PCI device slot assignment it is necessary to explicitly track the balloon device in the XML. This introduces a new device <memballoon model='virtio|xen'/> It can also have a PCI address, auto-assigned if necessary. The memballoon will be automatically added to all Xen and QEMU guests by default. * docs/schemas/domain.rng: Add <memballoon> element * src/conf/domain_conf.c, src/conf/domain_conf.h: parsing and formatting for memballoon device. Always add a memory balloon device to Xen/QEMU if none exists in XML * src/libvirt_private.syms: Export memballoon model APIs * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Honour the PCI device address in memory balloon device * tests/*: Update to test new functionality
