  Added:                libvirtd.confd-r2 libvirtd.init-r2
  Log:
  Add to the init script the shutting down of NATed networks created by libvirt itself. This functionality was written by Jan Vansteenkiste <jan@××××××.eu>. It complements the 'virt-network' USE flag.

# /etc/conf.d/libvirtd

# LIBVIRTD_OPTS
# You may want to add '--listen' to have libvirtd listen for tcp/ip connections
# if you want to use libvirt for remote control
# Please consult 'libvirtd --help' for more options
#LIBVIRTD_OPTS="--listen"

# LIBVIRTD_KVM_SHUTDOWN
# Valid options:
# * shutdown - Sends an ACPI shutdown (think when you tap the power button
# 				on your machine and it begins a graceful shutdown). If your
# 				VM ignores this, it will have the power yanked out from under
# 				it in LIBVIRTD_KVM_SHUTDOWN_MAXWAIT seconds.
# * managedsave - Performs a state save external to the VM. qemu-kvm will stop
# 				stop the CPU and save off all state to a separate file. When
# 				the machine is started again, it will resume like nothing ever
# 				happened. This is guarenteed to always successfully stop your
# 				machine and restart it. However it may take some time to finish.
# * none - No attempts will be made to stop any VMs. If you are restarting your
# 		machine the qemu-kvm process will be simply killed, which may result
# 		in your VMs having disk corruption.
LIBVIRTD_KVM_SHUTDOWN="managedsave"

# LIBVIRTD_KVM_SHUTDOWN_MAXWAIT
# Timeout in seconds until stopping libvirtd and "pulling the plug" on the
# remaining VM's still in a running state
#LIBVIRTD_KVM_SHUTDOWN_MAXWAIT="500"

# LIBVIRTD_NET_SHUTDOWN
# If libvirtd created networks for you (e.g. NATed networks) then this init
# script will shut them down for you if this is set to 'yes'. Otherwise,
# the networks will be left running once libvirt is shutdown. For this
# option to be useful you must have enabled the 'virt-network' USE flag and
# have had libvirt create a NATed network for you.
# Valid values: 'yes' or 'no'
#LIBVIRTD_NET_SHUTDOWN="yes"
