As you create a host group, consider the following:
A host group can include standalone hosts or clusters (collectively referred to simply as hosts).
A host can belong to only one group.
All hosts in a group must reside in the same zone.
All hosts in a group must be identical in terms of hypervisor technology and version, operating system version, network configuration, storage repository configuration, and hardware capabilities. This enables a workload to run on any of the group’s hosts.
All hosts that share the same repository must belong to the same host group. In other words, two different host groups cannot include hosts that share the same repository. You can view a host’s details in the Cloud Manager console to see its repositories.
If the host group is using the VMware hypervisor, the host group can contain hosts from one vCenter server only. Including hosts from multiple vCenter servers in the same host group is not supported.
To create a host group:
In the Cloud Manager console, click , then click the tab.
Click , select the zone that contains the hosts you plan to add to the host group, then click to display the Create Host Group dialog box.
In the fields, provide the following information for the host group:
Name: Specify a name for the group. The name should be different than any other host group name. This name is seen only by you and other Novell Cloud Manager administrators.
Zone: Displays the zone whose hosts you can add to the group. You cannot change this setting.
Hypervisor: Select the hypervisor technology for the group’s hosts. You will be able to add only those hosts that meet the hypervisor criteria.
Description: Provide any additional information for the host group.
In the fields, define the monthly costs associated with the host group resources:
vCPU: Specify the cost per virtual CPU.
Memory: Specify the cost per megabyte (MB) of memory.
Disk: Specify the cost per gigabyte (GB) of disk space.
Network: Specify the cost per network interface.
In the field, select the maximum number of virtual CPUs allowed for each host.
For example, if you select 32, the total vCPUs for all workloads running on a host cannot exceed 32.
Add hosts to the group:
In the list, click to display the Add Hosts dialog box.
The list displays all available hosts in the zone that meet the selected hypervisor criteria. Hosts that are already assigned to another host group are not displayed.
Select the hosts.
You can Shift-click and Ctrl-click to select multiple hosts.
Click to add the selected hosts to the list.
