# Testbed Setup
## Introduction
This directoctory contains the *high-level* process to set up a hardware
machine as a CSIT testbed, either for use as a physical testbed host or
as a VIRL server.
Code in this directory is NOT executed as part of a regular CSIT test case
but is stored here merely for archiving and documentation purposes.
## Setting up a hardware host
Documentation below is just bullet points and assumes and understanding
of PXE boot and ansible.
This process is specific for LF lab, and both examples given here as
well as associated code, are based on the assumption that they are run
in LF environment. If run elsewhere, changes will be required to IP addresses
and other parameters.
The process below assumes that there is a host used for boostrapping (referred
to as "PXE boostrap server" below), and that the directory containig this README
is available on the PXE bootstrap server in ~testuser/host-setup.
### Prepare the PXE bootstrap server (one-time)
- `sudo apt-get install isc-dhcp-server tftpd-hpa nginx-light ansible`
- `cd ~testuser/host-setup`
- `wget 'http://releases.ubuntu.com/14.04/ubuntu-14.04.4-server-amd64.iso'`
- `sudo mkdir /mnt/cdrom`
- `sudo mount -o loop ubuntu-14.04.4-server-amd64.iso /mnt/cdrom/`
- `sudo cp -r /mnt/cdrom/install/netboot/* /var/lib/tftpboot/`
- `sudo mkdir /usr/share/nginx/html/ubuntu`
- `sudo cp -r /mnt/cdrom/* /usr/share/nginx/html/ubuntu/`
- `sudo umount /mnt/cdrom`
- edit ks.cfg and replace IP address with that of your PXE bootstrap server
- `sudo cp ks.cfg /usr/share/nginx/html/ks.cfg`
- edit boot-screens_txt.cfg and replace IP address with that of your PXE bootstrap server
- `sudo cp boot-screens_txt.cfg /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg`
- `sudo cp syslinux.cfg /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/syslinux.cfg`
### New testbed host - manual preparation
- set CIMC address
- set CIMC username, password and hostname
### Bootstrap the host
From PXE boostrap server:
- `cd ~testuser/host-setup/cimc`
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d -i`
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d -s '<biosVfIntelHyperThreadingTech rn="Intel-HyperThreading-Tech" vpIntelHyperThreadingTech="disabled" />' -s '<biosVfEnhancedIntelSpeedStepTech rn="Enhanced-Intel-SpeedStep-Tech" vpEnhancedIntelSpeedStepTech="disabled" />' -s '<biosVfIntelTurboBoostTech rn="Intel-Turbo-Boost-Tech" vpIntelTurboBoostTech="disabled" />'`
- add MAC address to DHCP
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d -pxe`
While Ubuntu install is running:
- create RAID array. Reboot if needed.
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d --wipe`
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d -r -rl 1 -rs <disk size> -rd '[1,2]'`
Alternatively, create the RAID array manually.
- `./cimc.py -u admin -p Cisco1234 $CIMC_ADDRESS -d -hdd`
When installation is finished:
- `ssh-copy-id <>`
- `cd ~testuser/host-setup/playbooks`
- edit /etc/ansible/hosts; add the hosts you are installing. *REMOVE ANY HOSTS YOU ARE NOT CURRENTLY INSTALLING*.
Example for physical testbed hosts:
~~~
[tg]
10.30.51.16 hostname=t1-tg1
[sut]
10.30.51.17 hostname=t1-sut1
10.30.51.18 hostname=t1-sut2
~~~
Example for VIRL hosts -- use the "virl" tag and specify the flat network start and end addresses:
~~~
[virl]
10.30.51.28 hostname=t4-virl1 virl_l2_start=10.30.51.31 virl_l2_end=10.30.51.105
~~~
- `ansible-playbook --ask-sudo-pass 01-host-setup.yaml`
- `ansible-playbook reboot.yaml`
For non-VIRL hosts, stop here.
### VIRL installation
After the host has rebooted:
- `ansible-playbook 02-virl-bootstrap.yaml`
- ssh to host
- `sudo -s`
- `cd virl-bootstrap`
- `./virl-bootstrap-wrapper`
This command will error out when run the first time, as the VIRL host is not yet licensed.
Make sure we contact all three VIRL SALT masters:
- `for a in 1 2 4 ; do sudo salt-call --master us-${a}.virl.info test.ping ; done`
- Contact the VIRL team, provide the hostname and domain (linuxfoundation.org), and ask them
to accept the key
- After the key has been accepted, verify that connectivity with the SALT master is now OK:
`for a in 1 2 4 ; do sudo salt-call --master us-${a}.virl.info test.ping ; done`
- `./virl-bootstrap-wrapper`
- `reboot`
After reboot, ssh to host again
- as VIRL user, NOT AS ROOT:
- `vinstall all`
- `sudo reboot`
After reboot, ssh to host again
- as VIRL user:
- `sudo salt-call state.sls virl.routervms.all`
- `sudo salt-call state.sls virl.vmm.vmmall`
Back on the PXE bootstrap server:
- obtain the current server disk image and place it into
`files/virl-server-image/` as `server.qcow2`
TO-DO: Need to find a place to store this image
- `ansible-playbook 03-virl-post-install.yaml`
- Run the following command ONLY ONCE. Otherwise it will create
duplicates of the VIRL disk image:
`ansible-playbook 04-disk-image.yaml`
The VIRL host should now be operational. Test, and when ready, create a ~jenkins-in/status file with the appropriate status.
