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.
The virDomainObjPtr object stores state about a running domain. This object is shared across all drivers so it is not appropriate to include driver specific state here. This patch adds the ability to request a blob of private data per domain object instance. The driver must provide a allocator & deallocator for this purpose THis patch abuses the virCapabilitiesPtr structure for storing the allocator/deallocator callbacks, since it is already being abused for other internal things relating to parsing. This should be moved out into a separate object at some point. * src/conf/capabilities.h: Add privateDataAllocFunc and privateDataFreeFunc fields * src/conf/domain_conf.c: Invoke the driver allocators / deallocators when creating/freeing virDomainObjPtr instances. * src/conf/domain_conf.h: Pass virCapsPtr into virDomainAssignDef to allow access to the driver specific allocator function * src/lxc/lxc_driver.c, src/opennebula/one_driver.c, src/openvz/openvz_driver.c, src/qemu/qemu_driver.c, src/test/test_driver.c, src/uml/uml_driver.c: Update for change in virDomainAssignDef contract |

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.
