Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

Introduce support for VIR_MIGRATE_PEER2PEER in libvirt migration. Most of the changes occur at the source and no modifications at the receiver. In P2P mode there is only the Perform phase so we must handle the connection with the destination and actually perform the migration. libxlDomainPerformP2P implements the connection to the destination and libxlDoMigrateP2P implements the actual migration logic with virConnectPtr. In this function we take care of doing all phases of migration in the destination similar to virDomainMigrateVersion3Full. We appropriately save the last error reported in each of the phases to provide proper reporting. We don't yet support VIR_MIGRATE_TUNNELED and we always use V3 with extensible params, thus it also makes the implementation simpler. It is worth noting that the receiver didn't have any changes, and since it's still the v3 sequence thus it is possible to migrate from a P2P to non-P2P host.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
