Eric Blake 4f20226664 conf: prepare to track multiple host source files per <disk>
It's finally time to start tracking disk backing chains in
<domain> XML.  The first step is to start refactoring code
so that we have an object more convenient for representing
each host source resource in the context of a single guest
<disk>.  Ultimately, I plan to move the new type into src/util
where it can be reused by virStorageFile, but to make the
transition easier to review, this patch just creates the
new type then fixes everything until it compiles again.

* src/conf/domain_conf.h (_virDomainDiskDef): Split...
(_virDomainDiskSourceDef): ...to new struct.
(virDomainDiskAuthClear): Use new type.
* src/conf/domain_conf.c (virDomainDiskDefFree): Split...
(virDomainDiskSourceDefClear): ...to new function.
(virDomainDiskGetType, virDomainDiskSetType)
(virDomainDiskGetSource, virDomainDiskSetSource)
(virDomainDiskGetDriver, virDomainDiskSetDriver)
(virDomainDiskGetFormat, virDomainDiskSetFormat)
(virDomainDiskAuthClear, virDomainDiskGetActualType)
(virDomainDiskDefParseXML, virDomainDiskSourceDefFormat)
(virDomainDiskDefFormat, virDomainDiskDefForeachPath)
(virDomainDiskDefGetSecurityLabelDef)
(virDomainDiskSourceIsBlockType): Adjust all users.
* src/lxc/lxc_controller.c (virLXCControllerSetupDisk):
Likewise.
* src/lxc/lxc_driver.c (lxcDomainAttachDeviceMknodHelper):
Likewise.
* src/qemu/qemu_command.c (qemuAddRBDHost, qemuParseRBDString)
(qemuParseDriveURIString, qemuParseGlusterString)
(qemuParseISCSIString, qemuParseNBDString)
(qemuDomainDiskGetSourceString, qemuBuildDriveStr)
(qemuBuildCommandLine, qemuParseCommandLineDisk)
(qemuParseCommandLine): Likewise.

Likewise.

Likewise.

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.

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.
