Prepare a Linux Container (CT)
Requirements
- A console should be disabled (lxc.console = none)
- udev should not run in CT ($ mv /sbin/udevd{,.bcp})
Prepare a host environment
- Mount cgroupfs
$ mount -t cgroup c /cgroup
- Create a network bridge
# cat /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=dhcp ONBOOT=yes DELAY=5 NM_CONTROLLED=n $ cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE="eth0" NM_CONTROLLED="no" ONBOOT="yes" BRIDGE=br0
Create CT
- Download an OpenVZ template and extract it.
curl http://download.openvz.org/template/precreated/centos-6-x86_64.tar.gz | tar -xz -C test-lxc
- Create a config files
$ cat ~/test-lxc.conf lxc.console=none lxc.utsname = test-lxc lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 lxc.network.name = eth0 lxc.mount = /root/test-lxc/etc/fstab lxc.rootfs = /root/test-lxc-root/
$ cat /root/test-lxc/etc/fstab none /root/test-lxc-root/dev/pts devpts defaults 0 0 none /root/test-lxc-root/proc proc defaults 0 0 none /root/test-lxc-root/sys sysfs defaults 0 0 none /root/test-lxc-root/dev/shm tmpfs defaults 0 0
- Register CT
$ lxc-create -n test-lxc -f test-lxc.conf
- Start CT
$ mount --bind test-lxc test-lxc-root/ $ lxc-start -n test-lxc
