Xen users - Sep 2013 - R: [BUG] keyboard not working in xencenter console with Windows VM

same problem with Windows XP SP3
some problem accessing with XenCenter from different clients (XP and W7)

the only interesting logs seem:

SOLVED !!
modify /usr/lib/xcp/lib/vncterm-wrapper
substitute 127.0.0.1 con 0.0.0.0
disconnect XenCenter
create tunner with putty
link with vncviewer
