If I create a domain with a vfb:

    vfb=['type=vnc']
    vnc=1
    vncpasswd=''
    vnclisten='0.0.0.0'

then I can no longer access the Xen console:

    # xm create -c xenpv64
    Using config file "/etc/xen/xenpv64".
    Started domain xenpv64 (id=3)
    xenconsole: Could not read tty from store: No such file or directory

If I comment out the vfb line, then I can start the domain with a
console as expected.

Diffing xenstore is mostly boring except for:

    -   console = ""
    -    ring-ref = "401255"
    -    port = "2"
    -    limit = "1048576"
    -    type = "xenconsoled"
    -    tty = "/dev/pts/1"

    +   console = ""
    +    vnc-port = "5900"
    +    ring-ref = "277012"
    +    port = "2"
    +    limit = "1048576"
    +    type = "ioemu"

Can I have both at once?
