vcsim: Unable to set bootOrder of virtual machine

[Akasurde]

I am unable to set boot order for virtual machine created by vcsim,

from pyVim.connect import SmartConnect, Disconnect
import ssl
import atexit
from pyVmomi import vim

def connect():
    context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
    context.verify_mode = ssl.CERT_NONE

    si = SmartConnect(host='0.0.0.0', user='user', pwd='pass', port=443, sslContext=context)
    atexit.register(Disconnect, si)
    content = si.RetrieveContent()
    return content

def get_obj(content, vimtype, name):
    """
    Return an object by name, if name is None the
    first found object is returned
    """
    obj = None
    container = content.viewManager.CreateContainerView(
        content.rootFolder, vimtype, True)
    for c in container.view:
        if name:
            if c.name == name:
                obj = c
                break
        else:
            obj = c
            break

    container.Destroy()
    return obj

content = connect()
configSpec = vim.vm.ConfigSpec()
configSpec.bootOptions = vim.vm.BootOptions(bootOrder=[vim.vm.BootOptions.BootableDiskDevice(deviceKey=0)])
vm = get_obj(content, [vim.VirtualMachine], 'DC0_H0_VM0')
print("Boot Order before : %s" % vm.config.bootOptions)
vm.Reconfigure(configSpec)
print("Boot Order after : %s " % vm.config.bootOptions)

Expected Result:

vcsim should honour the bootOrder provided by bootOptions Config parameter.
