RE: [Xen-users] Xen Console
Hi guys,
I've been playing around with the built-in VNC and VNC server installed in
my HVM DomU these few days.
I realise if I will to sniff the packets in the network, I will be able to
pick up RFB packets between my host and my RealVNC server installed in the
DomU.
In contrast, there don't seems to be any RFB packets picked up by my
packet-sniffer when I'm using the built-in VNC.
Why is that so? What is the different between the connection of this two
methods?
