Click Load Datacenters to populate the list of data centers from your VMware vSphere environment.

From the Datacenter list, select a specific data center to manage from this list.

In the Fingerprint field, ensure that this field is populated with the fingerprint from the data center.

From the Display Type list, select a console type, for example, VNC or VMRC. Note that VNC consoles are unsupported on VMware ESXi 6.5 and later.

Optional: In the VNC Console Passwords field, select the Set a randomly generated password on the display connection checkbox to secure console access for new hosts with a randomly generated password. You can retrieve the password for the VNC console to access guest virtual machine console from the libvirtd host from the output of the following command:

# virsh edit your_VM_name
<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0' passwd='your_randomly_generated_password'>

From the Enable Caching list, you can select whether to enable caching of compute resources. For more information, see Caching of Compute Resources.

Click the Locations and Organizations tabs and verify that the values are automatically set to your current context. You can also add additional contexts.

Click Submit to save the connection.

In the orcharhino management UI, navigate to Infrastructure > Compute Resources.

From the Architecture list, select the operating system architecture.

In the Username field, enter the SSH user name for image access. By default, this is set to root.

From the User data list, select whether you want the images to support user data input, such as cloud-init data.

In the Password field, enter the SSH password for image access.

In the Image field, enter the relative path and name of the template on the vSphere environment. Do not include the data center in the relative path.

Click Submit to save the image details.

In the orcharhino management UI, navigate to Infrastructure > Compute Profiles.

Select a compute profile.

Select a Vmware compute resource.

In the CPUs field, enter the number of CPUs to allocate to the host.

In the Cores per socket field, enter the number of cores to allocate to each CPU.

In the Memory field, enter the amount of memory in MiB to allocate to the host.

In the Firmware checkbox, select either BIOS or UEFI as firmware for the host. By default, this is set to automatic.

In the Cluster list, select the name of the target host cluster on the VMware environment.

From the Resource pool list, select an available resource allocations for the host.

In the Folder list, select the folder to organize the host.

From the Guest OS list, select the operating system you want to use in VMware vSphere.

From the Virtual H/W version list, select the underlying VMware hardware abstraction to use for virtual machines.

If you want to add more memory while the virtual machine is powered on, select the Memory hot add checkbox.

If you want to add more CPUs while the virtual machine is powered on, select the CPU hot add checkbox.

If you want to add a CD-ROM drive, select the CD-ROM drive checkbox.

From the Boot order list, define the order in which the virtual machines tried to boot.

Optional: In the Annotation Notes field, enter an arbitrary description.

If you use image-based provisioning, select the image from the Image list.

From the SCSI controller list, select the disk access method for the host.

If you want to use eager zero thick provisioning, select the Eager zero checkbox. By default, the disk uses lazy zero thick provisioning.

From the Network Interfaces list, select the network parameters for the host’s network interface. At least one interface must point to a orcharhino Proxy-managed network.

Optional: Click Add Interface to create another network interfaces.

Click Submit to save the compute profile.

Create a compute profile:

# hammer compute-profile create --name "My_Compute_Profile"

Set VMware details to a compute profile:

# hammer compute-profile values create \
--compute-attributes "cpus=1,corespersocket=2,memory_mb=1024,cluster=MyCluster,path=MyVMs,start=true" \
--compute-profile "My_Compute_Profile" \
--compute-resource "My_VMware" \
--interface "compute_type=VirtualE1000,compute_network=mynetwork \
--volume "size_gb=20G,datastore=Data,name=myharddisk,thin=true"

In the orcharhino management UI, navigate to Hosts > Create Host.

In the Name field, enter a host name.

Click the Organization and Location tabs to ensure that the provisioning context is automatically set to the current context.

From the Host Group list, select the host group that you want to use to populate the form.

From the Deploy on list, select the VMware vSphere connection.

From the Compute Profile list, select a profile to use to automatically populate virtual machine-based settings.

Click the Interface tab and click Edit on the host’s interface.

Verify that the fields are automatically populated with values. Note in particular:

Ensure that the MAC address field is blank. The VMware vSphere server assigns one to the host.

Verify that the Managed, Primary, and Provision options are automatically selected for the first interface on the host. If not, select them.

In the interface window, review the VMware vSphere-specific fields that are populated with settings from our compute profile. Modify these settings to suit your needs.

Click the Operating System tab, and confirm that all fields automatically contain values.

Select the Provisioning Method that you want:

Click Resolve in Provisioning templates to check the new host can identify the right provisioning templates to use.

Click the Virtual Machine tab and confirm that these settings are populated with details from the host group and compute profile. Modify these settings to suit your requirements.

Click the Parameters tab and ensure that a parameter exists that provides an activation key. If a parameter does not exist, click + Add Parameter. In the field Name, enter kt_activation_keys. In the field Value, enter the name of the activation key used to register the Content Hosts.

Click Submit to provision your host on VMware.

In the orcharhino management UI, navigate to Hosts > Operating Systems, and select the operating system that you want to use for provisioning.

Click the Template tab.

From the Cloud-init template list, select Cloudinit default.
