console webpage should be more helpful for ParaVMs

From xela:

"""
I just created a VM, and having seen that it was up, clicked on it
the VM list. Which brought me to https://xvm.mit.edu/machine/4293/ ---
where I clicked on "Console" --- where I'm told:

Your machine appears to not be accepting VNC connections.
Perhaps you have a ParaVM machine?

Which is correct. Unfortunately the page gives me no clue what
to do about it. The link in the next line --- "See tips about
framebuffer and other issues --- didn't look very promising, but
since it's all there was, I followed it, and from there found my
way to https://xvm.mit.edu/help?subject=ParaVM%20Console

My suggestion is that you link "ParaVM" in the "Perhaps you have
a ParaVM machine?" message to that page.
"""

Seems like a good idea to me.
