[Qemu-devel] [PATCH v4 00/11] convert savevm to use qapi and introduce qmp command

[Pavel Hrdina <phrdina@redhat.com>]

This patch series convert the savevm command into qapi and introduce QMP
command vm-snapshot-save.
It also rewrite error report for functions used by this command.

The last patch introduce new functionality of savevm that you cannot override
existing snapshot without using 'force' parameter.

If non-blocking behaviour of this command is required and we cannot wait
until live snapshots will be finished, I could improve this basic command
to be non-blocking.

Changes from v3:
    - correct hopefully all error messages
    - proper commit message for 'qapi: Convert savevm'

Changes from v2:
    - correct error messages
    - introduce of 'force' option moved to qapi: Convert savevm
    - update of return value for used functions
    - drop of the speed improve because it isn't actually speed improve
    - vm-snapshot-save and savevm now returns snapshot information

Changes from v1:
    - rebase on current master branch
    - improve the speed of savevm
    - name parameter remains optionl for HMP and QMP
