[libvirt] [PATCH 0/3 v2] qemu: Allow serving VNC over a unix domain socket

[Cole Robinson]

This series enables use of qemu's -vnc unix:/some/socket/path functionality.
A qemu.conf option is provided to make this the default for VNC devices
without an explicit listen or socket value.

Serving VNC over a unix socket prevents unprivileged local users from
accessing a guest's console. The downside is that no clients currently
support it (though virt-manager support is ready), and certain
common usage scenarios cannot handle the tighter permissions (like a
regular user connecting to qemu:///system with policykit).

v2:
    schema: Make listen vs. socket a <choice>
    Add qemu.conf option for auto allocating a socket

Cole Robinson (3):
  qemu: Set domain def transient at beginning of startup process
  qemu: Allow serving VNC over a unix domain socket
  qemu: Add conf option to auto setup VNC unix sockets
