# Override the default config file
# NOTE: This setting is no longer honoured if using
# systemd. Set '--config /etc/libvirt/libvirtd.conf'
# in LIBVIRTD_ARGS instead.
#LIBVIRTD_CONFIG=/etc/libvirt/libvirtd.conf

# Listen for TCP/IP connections
# NB. must setup TLS/SSL keys prior to using this
#LIBVIRTD_ARGS="--listen"

# Override Kerberos service keytab for SASL/GSSAPI
#KRB5_KTNAME=/etc/libvirt/krb5.tab

# Override the QEMU/SDL default audio driver probing when
# starting virtual machines using SDL graphics
#
# NB these have no effect for VMs using VNC, unless vnc_allow_host_audio
# is enabled in /etc/libvirt/qemu.conf
#QEMU_AUDIO_DRV=sdl
#
#SDL_AUDIODRIVER=pulse

# Override the maximum number of opened files.
# This only works with traditional init scripts.
# In the systemd world, the limit can only be changed by overriding
# LimitNOFILE for libvirtd.service. To do that, just create a *.conf
# file in /etc/systemd/system/libvirtd.service.d/ (for example
# /etc/systemd/system/libvirtd.service.d/openfiles.conf) and write
# the following two lines in it:
#   [Service]
#   LimitNOFILE=2048
#
#LIBVIRTD_NOFILES_LIMIT=2048
