New subject: [PATCH V2 1/2] include: Define constant for save image format
Add a new VIR_DOMAIN_SAVE_PARAM_IMAGE_FORMAT typed parameter for
specifying the save image format. A format specified via the
virDomainSaveParams API overrides the save_image_format setting
in qemu.conf. The 'raw' format remains the default.

Hi Daniel,
Thanks for reviewing this and the related series! I suppose it's too late to
push these for 11.1.0? If so, I'll change the 'Since:' to 11.2.0 in patch1 and
push after the release.
Regards,
Jim

Hi Daniel,

push these for 11.1.0? If so, I'll change the 'Since:' to 11.2.0 in patch1
and push after the release.
I could kinda argue for the other series being a bugfix, but since its
motivation is mostly to assist this series, we might as well merge both
together after the release.
With regards,
Daniel
