[pve-devel] [PATCH-SERIES qemu-server 0/3] migration: conntrack: fix two edge cases

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

Because of a systemd issue [0], when a service that's 'partOf' a scope
fails, the scope itself might end up being left-over, even after all
processes in the scope exit. In particular, this can happen for the
'$vmid.scope' when the 'pve-dbus-vmstate@$vmid.service' fails.

As reported in the community forum [1], 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.
