managedsave command offloads the user from managing the save state file.
It does not need the user to specify saved state file location, all it takes
is domain name to identify. This makes it much more comfortable to use in
emergency where immediate shutdowm is needed. But it doesn't provide a way
to edit XML description of the save state file without user going through an
extra effort to search manually where the file actually exists.
The series aims to overcome the above constraints by adding new APIs and
commands to seemlessly edit the managed save state XML description using
just the domain name. The Patches mainly make use of the save-image-edit
code flow only to simplify the above use case.
This patch set provides capability to Dump and Edit the XML configuration
associated with a saved state file of a domain which was created by the
managedsave command.
The new command carry the similar options as the save-image-<XXX> commands
to change the running state as to paused state or running on start.
This is equivalent to:
virsh managedsave-dumpxml domain-name > state-file.xml
vi state-file.xml (or make changes with your other text editor)
virsh managedsave-define domain-name state-file-xml
or you can simply use:
virsh managedsave-edit domain-name
It's always better when we get more.
Changes since v1:
- qemu implementation called directly rather than going through
driver pointer in qemuDomainManagedSaveDefineXML.
- check whether the managed save state file exists and report a
error if it doesn't.
