Compute Configuration

Follow the steps below to configure the OpenStack Compute nodes:

1. Remove openvswitch $ sudo rmmod openvswitch

2.Disable the Apparmor program to allow the installation of PLUMgrid LXC.

$ sudo service apparmor stop 
$ sudo update-rc.d -f apparmor remove 
#(for Apparmor version>2.5.1 ) 
$ sudo /etc/init.d/apparmor teardown

3.Install the IO Visor module, iovisor-dkms 1.0.6-23 :

$ sudo apt-get install dkms iovisor-dkms

1. Install PLUMgrid puppet, plumgrid-puppet 5.0.0-b14 :

   $ sudo apt-get install plumgrid-puppet
   

2. Load the IO Visor module:

   $ sudo modprobe iovisor
   

3. Edit /etc/libvirt/qemu.conf and uncomment the section cgroup_device_acl and match with the following lines:

   cgroup_device_acl = [  
   "/dev/null", "/dev/full", "/dev/zero",  
   "/dev/random", "/dev/urandom", "/dev/net/tun",  
   "/dev/ptmx", "/dev/kvm", "/dev/kqemu",  
   "/dev/rtc","/dev/hpet", "/dev/vfio/vfio"  
   ]
   

7.Edit /etc/nova/nova.conf and set the provider as below:

[DEFAULT] 
libvirt_vif_type=ethernet 
libvirt_cpu_mode=none

1. Enable IPv4 forwarding:

   sysctl -w net.ipv4.ip_forward=1
   

2. Create the file, /etc/sudoers.d/ifc_ctl_sudoers and add the following content to it:

   nova ALL=(root) NOPASSWD: /opt/pg/bin/ifc_ctl_pp *
   

   Modify permissions for /etc/sudoers.d/ifc_ctl_sudoers

   $ sudo chown root:root /etc/sudoers.d/ifc_ctl_sudoers 
   $ sudo chmod 644 /etc/sudoers.d/ifc_ctl_sudoers
   

10.Install the PLUMgrid LXC:

$ sudo apt-get install plumgrid-lxc 
$ sudo apt-get -f install [to install dependencies]

Configure PLUMgrid Services on Compute Node:

Follow the steps below to configure PLUMgrid services on the Compute node:

1. Create /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/plumgrid.conf and add the following content:

   plumgrid_ip=<Management IP address of Director> 
   plumgrid_port=8001 
   mgmt_dev=<Management Interface> 
   label=<HOSTNAME OF THE MACHINE> 
   plumgrid_rsync_port=2222 
   plumgrid_rest_addr=0.0.0.0:9180 
   fabric_mode=host 
   plumgrid_syslog_ng_ip= 
   plumgrid_syslog_ng_port= 
   plumgrid_monitor_interval= 
   start_plumgrid_iovisor=yes 
   start_plumgrid=`/opt/pg/scripts/pg_is_director.sh $plumgrid_ip` 
   location=
   

   2.Add hostname of the Compute node to the file,
   /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hostname. Create the file if it does not exist. The hostname of the Compute node can be found by running the command, hostname -f 3.Create the file, /var/lib/libvirt/filesystems/plumgrid-data/conf/etc/hosts and add the following content to it:

   127.0.0.1   localhost 
   127.0.1.1   <FQDN> <Hostname>
   

2. Create the file, /var/lib/libvirt/filesystems/plumgrid-data/conf/pg/ifcs.conf and add the following content to it:

   <fabric_interface e.g. ens3 > = fabric_core host
   

   5.Restart the PLUMgrid service:

   $ sudo service plumgrid start
