  • Remove OVS and the package
# rmmod openvswitch
# apt-get purge openvswitch-*
  • Disable Apparmor in Ubuntu, this doest not allow lxc container to start.
# sudo service apparmor stop
# sudo update-rc.d -f apparmor remove
  • Install required package
# apt-get install -y dkms
# dpkg -i iovisor-dkms.deb
# apt-get install -y puppet
# dpkg -i plumgrid-puppet.deb
  • Install iovisor 
# modprobe iovisor
  • Enable IPv4 forwarding
# sysctl -w net.ipv4.ip_forward=1

Modify /etc/sysctl.conf

...
net.ipv4.ip_forward=1
...
  • Edit /etc/sudoers.d/ifc_ctl_sudoers
nova ALL=(root) NOPASSWD: /opt/pg/bin/ifc_ctl_pp *

execute the following command

# sudo chown root:root /etc/sudoers.d/ifc_ctl_sudoers
# sudo chmod 644 /etc/sudoers.d/ifc_ctl_sudoers
  • Install PLUMgird lxc container

PLUMgrid lxc have some versioning problem, it shall installed the missing dependency and the lxc was able to start

# apt-get install -y cgroup-lite

Install lxc debian package

# dpkg -i plumgrid-lxc.deb

If there's error, execute the following command to install its dependency.

# apt-get install -f
  • Copy plumgrid.conf template and edit
# cp -f /opt/pg/etc/puppet/modules/plumgrid/templates/plumgrid.conf.erb /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/plumgrid.conf

Edit it like the following: 

plumgrid_ip=<plumgrid_director_ip>
plumgrid_port=8001
mgmt_dev=br-mgmt
label=<node_hostname>
plumgrid_rsync_port=2222
plumgrid_rest_addr=0.0.0.0:9180
fabric_mode=host
start_plumgrid_iovisor=yes
start_plumgrid=`/opt/pg/scripts/pg/pg_is_director.sh $plumgrid_ip`

plumgrid_director_ip: A real IP to assign to plumgrid director node_hostname: hostname configured on the gateway

  • Edit /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hostname as 
<node_hostname>

Edit /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hosts as

...
127.0.0.1  <node_hostname>
...

node_hostname: hostname configured on the gateway

  • Edit /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/ifcs.conf 
br-mgmt = fabric_core host
<gateway-interface> = access_phys

gateway_interface: the physical interface connected to br-ex

  • start plumgrid service
# service plumgrid start
  • attach lxc 
# virsh -c lxc: lxc-enter-namespace plumgrid --noseclabel -- /bin/bash

and then restart plumgrid lxc container

# exit
# virsh -c lxc: destroy plumgrid
# virsh -c lxc: start plumgrid

If it failed to start plumgrid lxc container, check the trouble-shooting chapter.

  • Modify the MTU and flush iptables
# ifconfig eth0 mtu 1580
# iptables -F
  • Restart plumgrid service
# service plumgrid restart
