What do you mean by "configuring the vncserver manually on the guest"?

vncserver and xenfb are two completely orthogonal things. If you are
running vncserver in the guest then that is what you must configure,
xenfb settings have no impact on it.

xenfb corresponds /dev/fb0 in the guest surfaced via a vnc provider
(often qemu), there is no vncserver in the guest associated with xenfb.
