| + | === Add a new host === | ||
| + | It is critical that your opennebula front end can resolve the name of your hypervisors. In this scenario we will use the /etc/hosts file to do this for us.\\ | ||
| + | |||
| + | <code># vim /etc/hosts | ||
| + | |||
| + | 127.0.0.1 xenhost | ||
| + | |||
| + | :wq | ||
| + | </code> | ||
| + | |||
| + | |||
| + | Switch over to the oneadmin user and add your hosts.\\ | ||
| + | To add a host you use the onehost create command. This command needs to know the information manager (im) driver, the virtual machine monitor (vmm) driver and the network driver that the host is using. In our case we will be adding a xen hypervisor, that is set up to use open vSwitch for its network driver. | ||
| + | |||
| + | <code># su - oneadmin | ||
| + | ~$ onehost create xenhost -i im_xen -v vmm_xen -n ovswitch | ||
| + | </code> | ||
| + | |||
| + | Once complete you should now see your host on the onehost list, you can also use onehost show <hostid> to show the details of your host:\\ | ||
| + | |||
| + | <code> | ||
| + | oneadmin@xenhost:~$ onehost list | ||
