Configure Host as Hypervisor
You must configure hypervisor options for a host if you wish to use the host as a hypervisor on which the virtual machine (VM) instances will be created.
Before you can configure a host to work as a hypervisor, you must authorize the host. While authorizing the host, you must specify if you want to use the host as an SNAT host to route traffic from the private network to the public Internet.
You can change the hypervisor settings at any point after the host is authorized and no VM instances are running on the host.
If the host is already in use with VMs running on it, you cannot modify the VM Storage path for the host.
You must be an administrator to perform this operation.
To configure hypervisor options for a host, follow the steps given below.
- In the PMO UI, navigate to Infrastructure > Hosts tab.
- Select a host, then click ‘Configure Host’ action.
- Click the Hypervisor tab.
- Select the Make host a Hypervisor check box if you wish to make the host a hypervisor.
