Introduction
The Flowvisor service is responsible for slicing the network, therefore, guaranteeing the isolation of the experimentation.
Installation
Setting up a Virtual Machine
1. Generate a new Xen VM and access its console. (TEST)
To create the virtual machine which will host the flowvisor, run in your terminal the commands below. Pay attention to substitute the "XXX" for your Island ID and the "YYYY" for your Institution acronym.
xen-create-image --install-method=debootstrap --size 10G --memory 4098Mb --fs=ext3 --dist wheezy --pygrub --passwd --ip 10.XXX.0.101 --netmask=255.255.0.0 --gateway=10.XXX.0.30 --bridge=br_control --hostname=flowvisor.YYYY.org.br --mirror=http://archive.debian.org/debian/ xm create -c flowvisor.cfg
The first command will create the virtual machine and the second one will start up the VM and login in console mode.
Installing the Flowvisor
wget -q http://updates.onlab.us/GPG-KEY-ONLAB -O- | apt-key add - sh -c "echo 'deb http://updates.onlab.us/debian stable/' > /etc/apt/sources.list.d/flowvisor.list" apt-get update apt-get install flowvisor=0.8.17-3 sudo
Run the flowvisor configuration tool to set the password and create your certificate by changing the following parameters:
sudo -u flowvisor fvconfig generate /etc/flowvisor/config.json <hostname> <admin_passwd> [<of_port> <api_port>]
sudo -u flowvisor fvconfig generate /etc/flowvisor/config.json 10.XXX.0.101 ofelia
Enable the topology_server option in the flowvisor configuration file and then reload the configuration.
sudo -u flowvisor sed -i 's/"run_topology_server": false/"run_topology_server": true/' /etc/flowvisor/config.json sudo -u flowvisor fvconfig load /etc/flowvisor/config.json
To correct the flowvisor log behavior, edit the /etc/init.d/flowvisor startup script and add the -l parameter in the call to run the flowvisor:
sed -i -e "s/\/sbin\/flowvisor /\/sbin\/flowvisor -l /ig" /etc/init.d/flowvisor
Start the Flowvisor service upon boot:
update-rc.d flowvisor defaults /etc/init.d/flowvisor start
rm /usr/local/share/db/flowvisor/FlowVisorDB/*.lck /etc/init.d/flowvisor start
Check the Flowvisor service status.
# service flowvisor status FlowVisor is running as PID 4263
Log Configuration
After installing the Flowvisor service, configure the log level using this command:
sudo sed -i -e 's/log4j.rootCategory=[A-Z]*,/log4j.rootCategory=WARN,/' /etc/flowvisor/fvlog.config
The expected effect is to reduce the verbose of the log.
After this step, it will be necessary to configure the logrotate and the crontab:
Access the following directory:
cd /etc/logrotate.d
Create the following archive: flowvisor
And fill it with the following content:
/var/log/flowvisor/flowvisor-stderr.log {
daily
rotate 0
compress
copytruncate
}
After this step it will be necessary to configure the crontab:
crontab -e
Append the following line at the final:
0 12 * * * /usr/sbin/logrotate --force /etc/logrotate.d/flowvisor >/dev/null 2>$
