|
||||
#
|
||||
# qemu-system-x86_64 \
|
||||
# -net vde,sock=/var/run/kvm0.ctl,vlan=0 -net nic,vlan=0 \
|
||||
# [qemu_option [qemu_option], ...]
|
||||
#
|

# This will automatically connect the QEMU virtual machine to the VDE switch.
|

#
|
||||
# ---------------------------------------------------------------------------
|
||||
#
|
||||
# Network type can be one of "route" "bridge" or "nat":
|
||||
# - In "route" mode, the script will expect that the 'routed' daemon is running
|
||||
# on the host (see /etc/rc.d/rc.inet2 to start 'routed'), and will not
|
||||
# create iptables NAT rules.
|
||||
# The virtual network will be routed on the LAN and will be accessible as a
|
||||
# separate network segment (make sure the IP range defined below does not
|
||||
# conflict with existing parts of your network!). The guests will use our
|
||||
# private dnsmasq server to obtain IP addresses.
|
||||
# - In "bridge" mode, the script will try to add the tap device to an existing
|
||||
# network bridge, and will not create iptables NAT rules.
|
||||
# The guests will be seen on the LAN as part of the network.
|
||||
# - In "nat" mode, the script will create iptables NAT rules. These hide the
|
||||
# virtual network behind an internal NAT router. The guests will have full
|
||||
# network access, but will be accessible only from the host.
