1. Download newest version of nova-agent from the github repo to the server you want to upgrade : https:\/\/github.com\/rackerlabs\/openstack-guest-agents-unix\/releases<\/p>\n

For this instance I used “nova-agent-1.39-1.x86_64.rpm” since it’s CentOS \/ Redhat based<\/p>\n

2. Stop current nova-agent service<\/p>\n

\r\nservice nova-agent stop\r\n<\/pre>\n
3. Remove current in place nova-agent. I found the easiest way to do this is to just remove the entire contents of it’s directory.<\/p>\n
\r\nrm -rf \/usr\/share\/nova-agent\/*\r\n<\/pre>\n
4. Install the new nova-agent with the RPM<\/p>\n
\r\nrpm -ivh --nosignature nova-agent-1.39-1.x86_64.rpm\r\n<\/pre>\n
5. Start the new nova-agent service<\/p>\n
\r\nservice nova-agent start (might need to use systemd for CentOS\/RHEL 7 and above)\r\n# ie \r\nsystemctl enable nova-agent\r\nsystemctl start nova-agent\r\n<\/pre>\n
6. Issue a networking reset to verify it is working. Check logs and verify that you see this message : ‘resetnetwork’ completed with code ‘0’, message ”<\/p>\n
\r\nuuid=$(uuidgen)\r\nxenstore-write data\/host\/$uuid '{\"name\":\"resetnetwork\",\"value\":\"\"}'\r\n\r\ntail -20 \/var\/log\/nova-agent.log\r\n<\/pre>\n
That’s it! Once you’ve done that you should reboot to verify that the nova-agent comes up on boot but otherwise nothing else is needed. Hope it helps!<\/p>\n
