[PULL 03/45] qemu-config: use qemu_opts_from_qdict |
Date: |

Using qemu_opts_absorb_qdict, and then checking for any leftover options,
is redundant because there is already a function that does the same,
qemu_opts_from_qdict. qemu_opts_from_qdict consumes the whole dictionary
and therefore can just return an error message if an option fails to validate.
This also fixes a bug, because the "id" entry was retrieved in
qemu_config_do_parse and then left there by qemu_opts_absorb_qdict.
As a result, it was reported as an unrecognized option.
