snapshot: forbid snapshot on autodestroy domain
There is no reason to forbid pausing an autodestroy domain (not to mention that 'virsh start --paused --autodestroy' succeeds in creating a paused autodestroy domain). Meanwhile, qemu was failing to enforce the API documentation that autodestroy domains cannot be saved. And while the original documentation only mentioned save/restore, snapshots are another form of saving that are close enough in semantics as to make no sense on one-shot domains. * src/qemu/qemu_driver.c (qemudDomainSuspend): Drop bogus check. (qemuDomainSaveInternal, qemuDomainSnapshotCreateXML): Forbid saves of autodestroy domains. * src/libvirt.c (virDomainCreateWithFlags, virDomainCreateXML): Document snapshot interaction.
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.
