pvfb failure

[Amin <amino7@yahoo.com>]

Hi there,

I've been having no luck at all for about a week or two getting a vfb up. 
I'm using the latest changeset. Has anyone else had problems there?  This 
worked without issues before:

kernel="/boot/vmlinuz-2.6.18-xen"
ramdisk="/boot/initrd-2.6.18-xen.img"
name = "fc"
memory=256
disk=[ 'tap:aio:/home/xen/fc/disk.img,xvda1,w' ]
root="/dev/xvda1"
extra="ro xencons=xvc"
vif = [ 'mac=00:16:3e:2e:d7:66, bridge=xenbr0' ]
vfb = ['type=vnc,vncunused=1']


Now every time I start I get:
Error: Device 0 (vkbd) is already connected.

Log below.

Thanks
Amin
