What does it take for vnc to work with Xen .As far as I understand vnc
is inbuilt in Xen (at least for DomU)
As per this link
What I understand from this link
is xen-vncfb is the library which should be present.

I wanted to know with respect to a thread here (which is my question only)
the experiment was tried 7-8 months back where in I tried to create a
CentOS DomU on Debian Dom0 ,
this experiment had failed badly.

Now one fellow on the above form (Linuxquestions.org)  suggested he
had resolved similar problem by commenting out

vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]

Since I no more have the Debian thing and Xen working on it so I can
not test this part but

I would like to know (may my question will help many others)

1) Can I confirm via some link that the reply I got is correct?
2) Has any one experienced some thing similar if yes then what did
they do to resolve.

I remember I had created a Qemu guest also and then filled the LVM
with the QEMU guest files.
But things had not worked at that time as vnc was the only thing which
had failed.

Let me know what is some thing which one should check where some guest
creation is failing.
I remember a long time back a friend of mine had done some
installation when some libraries were giving problem by
doing a set -vx to the installer script and he was able to watch all
that was happening.
Is there some thing similar possible to know when a guest creation fails on Xen.

I do not remember the correct link but what I remember is
virt-manager and debootstrap have different mechanisms of creating
guests is this correct?
