libxl: remove domain when migration prepare fails
In libxlDomainMigrationPrepare(), a new virDomainObj is created from the incoming domain def and added to the driver's domain list, but never removed if there are subsequent failures during the prepare phase. targethost# virsh list --all sourcehost# virsh migrate --live dom xen+ssh://targethost/system error: operation failed: Fail to create socket for incoming migration. targethost# virsh list --all error: Failed to list domains error: name in virGetDomain must not be NULL After adding code to remove the domain on prepare failure, noticed that libvirtd crashed due to double free of the virDomainDef. Similar to the qemu driver, pass a pointer to virDomainDefPtr so it can be set to NULL once a virDomainObj is created from it.
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.

Description
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.
