[Lxc-users] LXC on Fedora

[Cristian Falcas]

I'm using the staging lxc on fedora 18 with fedora 18 guests, so it's working.

What i did (it's root all the waydown):
1. Compile lxc
cd ~
git clone https://github.com/lxc/lxc
cd  lxc
./autogen.sh && ./configure && make && make install

2. i didn't use the fedora template from lxc, but the openvz one (I
use x86 because of pentium4):
wget http://download.openvz.org/template/precreated/fedora-17-x86.tar.gz

3. uncompress in /mnt/files/lxc/fedora-x86/

4. Use this as the template:

 cat /mnt/files/lxc/lxc_template.conf
lxc.utsname = localhost.localdomain
lxc.rootfs = /mnt/files/lxc/fedora-x86/
#lxc.tty = 10

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = bridge_lxc
lxc.network.name = eth0
lxc.network.hwaddr = a2:cd:48:ff:ff:ff

lxc.autodev = 1
lxc.pts = 1024
lxc.arch = i386

#lxc.cgroup.devices.deny = a
lxc.cgroup.memory.limit_in_bytes = 128M
# /dev/null and zero
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
# consoles
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
lxc.cgroup.devices.allow = c 4:0 rwm
lxc.cgroup.devices.allow = c 4:1 rwm
# /dev/{,u}random
lxc.cgroup.devices.allow = c 1:9 rwm
lxc.cgroup.devices.allow = c 1:8 rwm
lxc.cgroup.devices.allow = c 136:* rwm
lxc.cgroup.devices.allow = c 5:2 rwm
# rtc
lxc.cgroup.devices.allow = c 254:0 rwm
# tun
lxc.cgroup.devices.allow = c 10:200 rwm

5. Create the bridge:

[root at wikitiki q]# cat /etc/sysconfig/network-scripts/ifcfg-bridge_lxc
DEVICE=bridge_lxc
TYPE=Bridge
NM_CONTROLED=no
BOOTPROTO=static
IPADDR=192.168.0.1
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes

6. dhcp configuration:

[root at wikitiki q]# cat /etc/dnsmasq.d/lxc.conf
interface=bridge_lxc
dhcp-range=192.168.0.0,static
dhcp-option=3,192.168.0.1
resolv-file=/etc/resolv.conf
domain-needed
bogus-priv
no-hosts
dns-forward-max=150
cache-size=1000
#no-negcache
neg-ttl=3600
no-poll

dhcp-host=a2:cd:48:02:02:02,192.168.0.2
dhcp-host=a2:cd:48:ff:ff:ff,192.168.0.222

7, start bridge, dhcp

8. Create the lxc:

lxc-create -n testes -f /path/to/template

9. start the container:

lxc-start -n testes

10. update fedora guest to 18

For me the lxc console is useless, so i use ssh to connect to the
container for any work.
