Accessing your VM

Lets ssh into our newly created box:

$ vagrant ssh <id>

Now you’re in your VM.

[[centos@dskl09 vpp-userdemo]$ vagrant ssh c1c
Welcome to Ubuntu 16.04 LTS (GNU/Linux 4.4.0-21-generic x86_64)

vagrant@localhost:~$

Note

Type exit if you want to exit your VM, or container (which we’ll get to soon.)

Let’s set up the hugepages:

$ sysctl -w vm.nr_hugepages=1024

vagrant@localhost:~ sysctl: permission denied on key 'vm.nr_hugepages'

Oh no! What happened? We’re not root. Lets change to root.

$ sudo bash

Then we can perform the previous sysctl command with no issues.

To check if it was set correctly:

$ HUGEPAGES=`sysctl -n  vm.nr_hugepages`
$ echo $HUGEPAGES

Which should output 1024.

Now we want to add the VPP repo as to our sources list in our VM. We append the FD.io binary repo to a file called 99fd.io.list, so apt-get update and install can use it:

ls /etc/apt # here is where you can see your sources.list.d directory after doing this command below

echo "deb [trusted=yes] https://nexus.fd.io/content/repositories/fd.io.ubuntu.xenial.main/ ./" | sudo tee -a /etc/apt/sources.list.d/99fd.io.list

Do an apt-get to make sure the VM and its libraries are updated:

$ apt-get update

Now we want to install VPP and lxc (for our containers):

$ apt-get install vpp vpp-lib vpp-dpdk-dkms bridge-utils lxc

Now we can start running VPP on our host VM:

$ service vpp start

Check if we installed lxc:

$ lxc-checkconfig
