[Qemu-devel] Regarding the status of Gluster's multi volfile server patches

[Prasanna Kalever]

Hello,

Can someone please help me in tracking the QAPI changes for union
discriminator addition,
the below [1] gluster related patches are awaiting from very long,
because of the dependency with QMP design changes.

These patches [1] also stuck changes in libvirt/vdsm. It will be
really helpful for us, if someone can suggest what can be done to
accept this patches as early as possible.

Many thanks in advance.

Hi Prasanna,

The last I know, as of v15 / v16, is that the libvirt team (Eric Blake)
still has outstanding concerns on the QAPI interface.

Eric, are your concerns regarding the API for this series still outstanding,
or is this something you'd be comfortable supporting in libvirt with the
current proposed interface?

Thanks,
Jeff

I've currently posted all patches in my working tree, but review says I
need another round of review before it gets merged:
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg03569.html
https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg03900.html

I'm also one or two patches shy of being able to use one union type as
the branch of another flat union type, where I still have to write the
patch, but it should be easy on top of the qapi patches that have landed
so far.

I also know that we want to get NBD converted for blockdev-add at the
same time, and that NBD, gluster, sheepdog, and other network-based
devices will share similar issues, so on my plate is to review this series:
https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg01048.html

Can you please point me to the last proposal for gluster, and/or repost
any series you have for proposing the idea?  I want to help get working
blockdev-add into 2.7 if at all possible.

Eric, here are the series of patches that are posted from my side for
the very last time (2-3 months old).
https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg06324.html
https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg06326.html
https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg06325.html
https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg06327.html
https://lists.gnu.org/archive/html/qemu-devel/2016-03/msg06328.html

I expect that they face merge conflicts on latest master, I'll re-base
them and send sometime today.


Thanks,
