2 years back I proposed dropping the sheepdog mailing list from the MAINTAINERS file, but somehow the patch never got picked up: https://lists.gnu.org/archive/html/qemu-block/2018-03/msg01048.html So here I am with the same patch again. This time I go further and deprecate the sheepdog driver entirely. See the rationale in the second patch commit message. Daniel P.

Upstream looks like it's unmaintained now, with no commits in over two years: https://github.com/sheepdog/sheepdog/commits/master Can we also get a corresponding change to eliminate this from libvirt?

This is only deprecation in QEMU, the feature still exists and is intended to be as fully functional as in previous releases. Assuming QEMU actually deletes the feature at end of the deprecation cycle, then libvirt would look at removing its own support.

Libvirt is not intended to support all Qemu features and I'm sure it doesn't. Amd it can safely deprecate features even if they are not-deprecated in Qemu. The only possible conflict is when Qemu wants to deprecate something that Libvirt wants to continue support for (or even can't live without). -- Best regards, Vladimir

There are two sheepdog-related bits in libvirt which are IMO completely separate: 1) the blockdev backend handling for the 'sheepdog' protocol driver This is the one connected to qemu's deprecation, but until there is a qemu version where sheepdog wasn't deprecated/removed supported by libvirt we can't really do much about it. On the other hand it's just a few generators of arguments for -drive/-blockdev so the burden is very low. 2) the sheepdog storage driver This one is completely separate from qemu and we can decide to deprecate/delete it at our own schedule as it will not influence the ability to start VMs. The last non-housekeeping commit in that driver seems to be dated: Thu Jun 18 16:20:42 2015 Similarly the burden of keeping this around is low, but I would not bat an eye if we remove it right away even.
