Hi Boneyard,
You can use a virtual console (vconsole) for this:
Manual Chapter: Working with vCMP Guests
https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/vcmp-admin-11-2-0/7.html
Accessing a vCMP guest using the vconsole utility
Before accessing a vCMP guest, verify that you have configured at least one self IP address on the guest.
You can access an individual VM of a guest after you have created the guest. Console access is available only for guests whose network mode is Isolated.
Note: When you reboot the guest from within the vconsole utility, the BIG-IP system terminates your connection to the guest. You can access the guest again when the reboot operation is finished.
From a system on the external network, open a serial console utility.
In the utility, type the management IP address of the vCMP host. This displays a console window for logging in to the BIG-IP system.
Using your user name and password credentials, log in to the BIG-IP system.
From the command line prompt, use the telnet-based vconsole utility and specify a guest name (and for all-slot guests only, a slot number) to log in to a guest VM. You can do this at the system prompt or from within tmsh.
Option Command sequence
From the system prompt Type run util vconsole guest_name slot_number
From the tmsh prompt Type vconsole guest_name slot_number
Valid slot numbers are 1, 2, 3, and 4.
You are now logged in to a guest VM.
