Installing Nova Agent Linux on Xen Guest VM

So, sometimes every now and then a customer wants to use a custom image with our services. The thing is for the build to succesfully complete and the VM to get networking, it needs to be able to communicate with lil ole nova-agent.


1. Download the nova-agent-linux

cd ~/
mkdir nova-agent
cd nova-agent

2. Extract and run installer script

tar xzf nova-agent-Linux-x86_64-1.39.0.tar.gz

3. Inject LSB headers into the script (if not already there)

sed '1i### BEGIN INIT INFO\n# Provides: Nova-Agent\n# Required-Start: $remote_fs $syslog\n# Required-Stop: $remote_fs $syslog\n# Default-Start: 2 3 4 5\n# Default-Stop: 0 1 6\n# Short-Description: Start daemon at boot time\n# Description: Enable service provided by daemon.\n### END INIT INFO\n' /usr/share/nova-agent/1.39.0/etc/generic/nova-agent > /usr/share/nova-agent/1.39.0/etc/generic/nova-agent.lsb

4. Move the init script in place and make it executable

cp -av /usr/share/nova-agent/1.39.0/etc/generic/nova-agent.lsb /etc/init.d/nova-agent
chmod +x /etc/init.d/nova-agent

5. Set the script to start automatically in the event of a reboot.

# RHEL, CentOS, Fedora, OpenSuse
chkconfig nova-agent on

# Debian, Ubuntu
update-rc.d -f nova-agent defaults
