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.

Shanzhi Yu 9f974858dd qemu: snapshot: inactive external snapshot can't work after libvirtd restart
When create inactive external snapshot, after update disk definitions,
virDomainSaveConfig is needed, if not after restart libvirtd the new snapshot
file definitions in xml will be lost.

Reproduce steps:

1. prepare a shut off guest
$ virsh domstate rhel7 && virsh domblklist rhel7
shut off

Target     Source
------------------------------------------------
vda        /var/lib/libvirt/images/rhel7.img

2. create external disk snapshot
$ virsh snapshot-create rhel7 --disk-only && virsh domblklist rhel7
Domain snapshot 1417882967 created
Target     Source
------------------------------------------------
vda        /var/lib/libvirt/images/rhel7.1417882967

3. restart libvirtd then check guest source file
$ service  libvirtd restart && virsh domblklist rhel7
Redirecting to /bin/systemctl restart  libvirtd.service
Target     Source
------------------------------------------------
vda        /var/lib/libvirt/images/rhel7.img

         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.
