Need to capture console/screen for vsphere

I am trying to install virtual machine on esxi through pyvmomi (version : 6.0.0.2016.6) using python (version : 2.7.3).
when machine is powered on ,i need to input some boot parameters and based on that i need to input username, password and select other parameters from the menu displayed during os installation.
Can you please let me know which library/api's will help me in doing this? How can i achieve this thing.

I got to know about MKS ticket but don't know how to use it.

from pyVim import connect
from pyVmomi import vim
si = connect.SmartConnect(host='10.164.72.35',user='root', pwd='temp123')
atexit.register(connect.Disconnect, si)
vm=None
content = si.content
objView = content.viewManager.CreateContainerView(content.rootFolder,
[vim.VirtualMachine],
True)
vmList = objView.view
for curr_vm in vmList:
if curr_vm.name == "myvm":
vm = curr_vm
break
objView.Destroy()

ticket = vm.AcquireTicket("mks")

ticket = vm.AcquireMksTicket()

Start with the pyVim/pyVmomi usage shown in the issue and the AcquireMksTicket entry point. Determine the supported way to capture the VM console and provide installation input, then verify it against the vSphere API behavior; done means a reproducible console-interaction flow is documented.
