This is an untested mess.

Place the following in /etc/default/lxc-net to configure the network:
|
|
|
|
---
|
|
|
|
# Leave USE_LXC_BRIDGE as "true" if you want to use lx
|
|
cbr0 for your
|
|
# containers. Set to "false" if you'll use virbr0 or
|
|
another existing
|
|
# bridge, or mavlan to your host's NIC.
|
|
USE_LXC_BRIDGE="true"
|
|
|
|
# If you change the LXC_BRIDGE to something other than
|
|
lxcbr0, then
|
|
# you will also need to update your /etc/lxc/default.c
|
|
onf as well as the
|
|
# configuration (/var/lib/lxc/<container>/config) for
|
|
any containers
|
|
# already created using the default config to reflect
|
|
the new bridge
|
|
# name.
|
|
# If you have the dnsmasq daemon installed, you'll als
|
|
o have to update
|
|
# /etc/dnsmasq.d/lxc and restart the system wide dnsma
|
|
sq daemon.
|
|
LXC_BRIDGE="lxcbr0"
|
|
LXC_ADDR="10.0.3.1"
|
|
LXC_NETMASK="255.255.255.0"
|
|
LXC_NETWORK="10.0.3.0/24"
|
|
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
|
|
LXC_DHCP_MAX="253"
|
|
# Uncomment the next line if you'd like to use a conf-
|
|
file for the lxcbr0
|
|
# dnsmasq. For instance, you can use 'dhcp-host=mail1
|
|
,10.0.3.100' to have
|
|
# container 'mail1' always get ip address 10.0.3.100.
|
|
#LXC_DHCP_CONFILE=/etc/lxc/dnsmasq.conf
|
|
|
|
# Uncomment the next line if you want lxcbr0's dnsmasq
|
|
to resolve the .lxc
|
|
# domain. You can then add "server=/lxc/10.0.3.1' (or
|
|
your actual $LXC_ADDR)
|
|
# to your system dnsmasq configuration file (normally
|
|
/etc/dnsmasq.conf,
|
|
# or /etc/NetworkManager/dnsmasq.d/lxc.conf on systems
|
|
that use NetworkManager).
|
|
# Once these changes are made, restart the lxc-net and
|
|
network-manager services.
|
|
# 'container1.lxc' will then resolve on your host.
|
|
#LXC_DOMAIN="lxc"
|

|
|
Then start the lxc NAT:
|
|
|
|
> sudo systemctl start lxc-net
|
|
|
|
> sudo systemctl restart NetworkManager
|
|
|
|
... and make sure the bridge's ip-range doesn't intefere withe local network.
|
|
|
|
> sudo arp-scan -I lxcbr0 -l
|
|
|
|
The lxc template is in /etc/lxc/default.conf. You need to modify it so that it uses lxcbr0.
|
|
|
|
---
|
|
|
|
/etc/lxc/default.conf
|
|
lxc.net.0.type = veth
|
|
lxc.net.0.link = lxcbr0
|
|
lxc.net.0.flags = up
|
|
lxc.net.0.hwaddr = 00:16:3e:xx:xx:xx

Arch linux containers take up about 600 Megs.
|
|
|
|
To speed up the startup process, one can install haveged and start the haveged.service. Haveged stops the wait-time for system entropy creation.
|
|
|
|
Machines are stored in /var/lib/lxc.
