As part of the work on backing chains, I'm finding that it would be easier to directly manipulate chains of pointers (adding a snapshot merely adjusts pointers to form the correct list) rather than copy data from one struct to another. This patch converts domain disk source to be a pointer. In this patch, the pointer is ALWAYS allocated (thanks in part to the previous patch forwarding all disk def allocation through a common point), and all other changse are just mechanical fallout of the new type; there should be no functional change. It is possible that we may want to leave the pointer NULL for a cdrom with no medium in a later patch, but as that requires a closer audit of the source to ensure we don't fault on a null dereference, I didn't do it here. * src/conf/domain_conf.h (_virDomainDiskDef): Change type of src. * src/conf/domain_conf.c: Adjust all clients. * src/security/security_selinux.c: Likewise. * src/qemu/qemu_domain.c: Likewise. * src/qemu/qemu_command.c: Likewise. * src/qemu/qemu_conf.c: Likewise. * src/qemu/qemu_process.c: Likewise. * src/qemu/qemu_migration.c: Likewise. * src/qemu/qemu_driver.c: Likewise. * src/lxc/lxc_driver.c: Likewise. * src/lxc/lxc_controller.c: Likewise. * tests/securityselinuxlabeltest.c: Likewise.

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.
