Creating a vCMP guest

Before you create a vCMP™ guest, you must log in to the vCMP host to configure the base network.
You create a vCMP guest when you want to configure and run one or more BIG-IP® modules as though the modules were running together on their own BIG-IP device. For example, you can create a guest that runs BIG-IP® Local Traffic Manager™ and BIG-IP® Global Traffic Manager™. A guest can run on one available slot or all available slots of a chassis.
Note: This procedure creates a guest in Bridged mode.
Note: When creating a guest, if you see the error message Insufficient disk space on /shared/vmdisks. Need 24354M additional space., you must delete existing virtual disks until you have freed up 24354 MB of disk space.
  1. Log in to the vCMP host (hypervisor) and access the BIG-IP Configuration utility, using the management IP address of the vCMP host.
  2. On the Main tab, click vCMP.
  3. Click Create.
  4. From the Properties list, select Advanced.
  5. In the Name field, type a name for the guest.
  6. In the Host Name field, type the host name of the BIG-IP system. Ensure that you assign a fully-qualified domain name (FQDN). If you assign a name that is not an FQDN, the system might display an error message. If you leave this field blank, the system assigns the name localhost.localdomain.
  7. From the Number of Slots list, select either Single Slot or All Slots. This causes the guest to reside on one slot or to span all slots. Note that once you configure a guest to span all slots, you cannot change this value later to Single Slot, unless you first change the state of the guest to Configured.
  8. For the Cluster IP Address setting:
    1. In the IP Address field, type a unique management IP address that you want to assign to the guest. You use this IP address to access the guest when you want to manage a module running within the guest.
    2. In the Network Mask field, type the network mask for the cluster IP address.
    3. In the Management Route field, type a gateway address for the cluster IP address.
  9. From the Initial Image list, select an ISO image file for installing TMOS® and any licensed BIG-IP modules onto the guest's virtual disk.
  10. From the Virtual Disk list, retain the default value of None. The BIG-IP system creates a virtual disk with a default name (the guest name plus the string .img, such as guestA.img). Note that if an unattached virtual disk file with that default name already exists, the system displays a message, and you must manually attach the virtual disk. You can do this using the tmsh command line interface.
  11. For the VLAN List setting, select an internal and an external VLAN name from the Available box, and using the Move button, move the VLAN names to the Selected box.
  12. From the Requested State list, select Provisioned. This allocates all necessary resources to the guest, such as CPU cores, virtual disk, and so on.
  13. From the Management Network list, select Bridged.
  14. Click Finish.
After clicking Finished, you must wait while the system installs the selected ISO image onto the guest's virtual disk. When this process is complete, you can deploy the guest.

Setting a vCMP guest to the Deployed state

When you deploy a vCMP guest, you can then provision any BIG-IP® modules that you want to run within that guest.
  1. Ensure that you are still logged in to the vCMP host using the BIG-IP system's cluster IP address.
  2. On the Main tab, click vCMP.
  3. In the Name column, click the name of the vCMP guest that you want to deploy.
  4. From the Requested State list, select Deployed.
  5. Click Update.
After moving a vCMP guest to the Deployed state, you must wait while the guest boots and becomes accessible. Then, you can log into the vCMP guest to provision specific BIG-IP modules.

vCMP guest configuration settings

This topic describes the settings that you can configure for a vCMP guest.

Property Name Value Description
Name A name in alphanumeric format Any meaningful name, such as guestA.
Host Name A fully-qualified domain name (FQDN) The FQDN that you assign to the guest. If you do not provide an FQDN, the BIG-IP system assigns a default name that contains the guest name plus the string localdomain. An example of a default host name for a guest is guestA.localdomain.
Note: If you change this property on a guest that is already in the Deployed state, the BIG-IP system propagates the change immediately to all VMs of the guest.
Memory A numeric range The total amount of memory that the system has allocated to the guest. This is a read-only property.
Provisioned Storage A numeric range The total amount of storage that the system allocated to the guest during provisioning. This is a read-only property.
Number of Slots Single Slot or All Slots The number of slots on which you want the vCMP guest to run. This value can be either one slot or all slots in the cluster. For example, if the system-wide cluster consists of three members, then selecting All Slots results in the guest spanning three slots and consisting of three VMs.
Cluster IP Address An IP address A floating management IP address that you use to manage the guest. The BIG-IP system assigns this IP address to the primary cluster member for the guest. This address is called the cluster IP address because you use it to manage the cluster of VMs that make up the guest. If you intend to set the network mode to Bridged, you can ensure management access to the guest by configuring this IP address to be on the same IP subnet, or in the same Layer 2 broadcast domain, as the vCMP host's management interface.
Note: If you change this property on a guest that is already in the Deployed state, the BIG-IP system propagates the change immediately to all VMs of the guest.
Network Mask A network mask The network mask for the specified cluster IP address.
Note: If you change this property on a guest that is already in the Deployed state, the BIG-IP system propagates the change immediately to all VMS of the guest.
Management Route An IP address The IP address for the gateway required to reach the specified cluster IP address. The management route address must be on the same subnet as the cluster IP address. In fact, if you intend to set the network mode to Bridged, you typically configure this IP address to be identical to the management route of the vCMP host.
Note: If you change this property on a guest that is already in the Deployed state, the BIG-IP system propagates the change immediately to all VMs of the guest.
Initial Image A file name with an .iso extension The ISO image of the TMOS hypervisor instance that you want to install on the guest's virtual disk.
Virtual Disk A file name with an .img extension The portion of the physical disk space that is allocated to the guest.
VLAN List Any existing VLAN name The tagged VLANs that the guest uses to communicate with other guests, the host, and with the external network. The available VLANs in the list are those that are currently configured on the vCMP host. If you have upgraded the BIG-IP system from a previous version, be aware that the tags for the VLANs you select from this list must match the tags for the VLANs contained in the archive data that you loaded for the guest.
Note: If you change this property on a guest that is already in the Deployed state, the BIG-IP system propagates the change immediately to all slots of the guest.
Requested State Configured, Provisioned, or Deployed The state of the vCMP guest. A guest can manage traffic in the Deployed state only.
Management Network Bridged or Isolated The network mode of the vCMP guest. In Bridged mode, the guest can communicate with the vCMP host's management network. In Isolated mode, the guest is isolated from the vCMP host's management network.
