[pve-devel] [PATCH-SERIES common/qemu-server v2 0/2] migration: conntrack: fix race adding dbus-vmstate object to QEMU

[Fiona Ebner <f.ebner@proxmox.com>]

Changes in v2:
* Dropped already applied patches.
* Introduce sd_notify() helper.
* Different approach, make the service type=notify instead of waiting
  in a sleep+check-loop until the object shows up via QMP 'qom-list'.

As reported in the community forum [0], it might happen that the
dbus-vmstate object is not added (quickly enough) to the target QEMU
instance, before the migration state is loaded. This would result in
a crash of the target instance.

Dependency bump qemu-server -> pve-common needed.
