hi Dan, I think it over, and seems more concern, see below,

Hi Daniel,

Here I have another question on virt-manager, as you write "an embedded VNC client viewer provides console access to each of the guest domains", my concern is where is the vnc server, who provide it, and start it? Need we setup vnc? I looked through the process used to create guest, seems there is no any step for vnc...

The VNC server depends on what type of domain is being run. For HVM guests
the VNC server is provided by the qemu-dm process assoicated with that
guest. For paravirt guests, VNC is only available if you have the paravirt
framebuffer patches applied to your xen tree - these are not in xen-unstable
yet. In paravirt, XenD will launch a xen-vncfb process to provide the VNC
due to vnc connection is required by vnc-viewer, vnc-viewer can present the graphical console, because there is no paravirt framebuffer patches applied to xen-unstable, so virt-manager can't work with xen-unstable for paravirt guests, because we can't get the graphical console run. is it right?

xen-unstable should be the latest version of Xen, if it has no paravirt framebuffer patches, maybe xen-stable should have no either? and if so, we may say virt-manager not support paravirt at the moment?
So in both case all you need to do is set 'vnc=1' in the guest
config file & XenD will ensure the VNC servers are started as required.
