This is v4 patchset of modified 'migrate' and 'migrate-incoming' QAPI design for upstream review.
Link to previous upstream community patchset links: v1: https://lists.gnu.org/archive/html/qemu-devel/2022-12/msg04339.html v2: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg02106.html v3: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg02473.html Changelog: ---------- - Restructured the patchset into 8 different independently build patches. - Patches [1-2] focused on introducing MigrateAddress struct to QAPIs - Patches [3-5] focused on implementing modified QAPI design to transport backends like (socket, exec and rdma). - Patches [6-8] focused on introducing MigrateChannelList struct on top of MigrateAddress QAPI as an additional argument to both migration QAPIs and also implemented in the migration code path. v4 series look a longer time to post, as it was blocked because of improvment change required on the qapi design level to allow 'unions inside another union'. For detailed discussion on this, please follow the upstream discussion here: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg06782.html https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg06783.html I would like to thank Markus and Daniel for merging patches to allow union inside another union and also would like to thank Eric for his reviews on the patches.
