Modifying the xml on either save or restore only gets you so far - you have to remember to 'virsh dumpxml dom' just prior to the 'virsh save' in order to have an xml file worth modifying that won't be rejected due to abi breaks. To make this more powerful, we need a way to grab the xml embedded within a state file, and from there, it's not much harder to also support modifying a state file in-place. Also, virDomainGetXMLDesc didn't document its flags. * include/libvirt/libvirt.h.in (virDomainSaveImageGetXMLDesc) (virDomainSaveImageDefineXML): New prototypes. * src/libvirt.c (virDomainSaveImageGetXMLDesc) (virDomainSaveImageDefineXML): New API. * src/libvirt_public.syms: Export them. * src/driver.h (virDrvDomainSaveImageGetXMLDesc) (virDrvDomainSaveImgeDefineXML): New driver callbacks.
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.
