[pve-devel] [PATCH qemu-server 06/14] api2: qemu: add module exposing node migration capabilities

[Christoph Heiss <c.heiss@proxmox.com>]

Similar to the already existing ones for CPU and QEMU machine support.

Very simple for now, only provides one property for now:

  'has-dbus-vmstate' - Whether the dbus-vmstate is available/installed
