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.

Corey S. McQuay 8ee8f939fe qemu: migration: Disallow migration of read only disk
Currently Libvirt allows attempts to migrate read only disks. Qemu
cannot handle this as read only disks cannot be written to on the
destination system. The end result is a cryptic error message and a
failed migration.

This patch causes migration to fail earlier and provides a meaningful
error message stating that migrating read only disks is not supported.

         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.
