Clarify direct migration
When --direct is used when migrating a domain running on a hypervisor that does not support direct migration (such as QEMU), the caller would get the following error message: this function is not supported by the connection driver: virDomainMigrateToURI2 which is a complete nonsense since qemu driver implements virDomainMigrateToURI2. This patch would emit a more sensible error in this case: Requested operation is not valid: direct migration is not supported by the connection driver (cherry picked from commit 3189dfb1636da22d426d2fc07cc9f60304b16c5c)

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. Daniel Veillard <veillard@redhat.com>
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.
