libvirt users - Sep 2011 - Graphical framebuffers confuse, XML format about spice

Hello, i want to start a guest OS in the server, and use spice to achieve
graphical interaction with the guest OS. But when i config the XML file, i
was confuse by spice .
The graphic node is :
 <graphics type='spice' port='5990' ><listen
type='address'
address='127.0.0.1'/></graphics>

but is has such error as below :
libvir: QEMU error : internal error process exited while connecting to
monitor: qemu-spice: -spice port=5990,addr=127.0.0.1,disable-ticketing:
Invalid parameter 'addr'
parse error: port=5990,addr=127.0.0.1,disable-ticketing

What is the meaning of <listen type='address'
address='*****'/>,  If the
localhost IP is A and the spice-server IP is B. what should i set the listen
type ? to start the Domain   and to achieve  graphical interaction with the
guest OS.

When i set the Graphic node as :

    <graphics type='spice'>
      <listen type='network' network='rednet'/>
    </graphics>

the Error is :
libvir: QEMU error : XML error: listen network 'rednet' had no usable
address

what should i do to achieve  graphical interaction with the guest OS ??

Apparently your "qemu-spice" binary supports the -spice option, but 
doesn't support the addr option. That seems very strange. What is the 
origin of "qemu-spice", and what version does it display?

This is a new syntax starting in libvirt 0.9.4 that allows describing 
the address to listen on either as an IP address/domain name, or as a 
network name ("network name" referring to one of the virtual networks 
defined by libvirt)

You can leave it at the default of localhost (127.0.0.1) as long as your 
spice client (e.g. virt-manager) is running on the same machine. You 
would only want to change the address to something else if you needed to 
connect directly to the guest's spice server from a different physical 
machine, and in that case you would set the address to one of the 
physical interfaces on the host (*not* the guest).

However, this is not the cause of your original problem - your qemu 
binary doesn't like the -spice option as constructed by libvirt; there 
is something old / non-standard about this qemu.

(please reply to the list rather than personal mail)

Where did the original "qemu-spice" come from? That's not an
official
Fedora13 package, and in later versions of Fedora, spice support is 
included in the standard qemu-kvm package. It sounds like you either 
built qemu + a spice patch from source, or found a prebuilt package like 
that somewhere.

I've only used the spice support that is integrated into the qemu-kvm 
package of Fedora 14 and RHEL (the qemu-kvm in Fedora 13 is too old to 
have spice support, and Fedora 13 is now officially out of support mode)

I would do one of these things:

1) try getting a source tarball for a more recent qemu-kvm release and 
build/install that on your F13 machine.

2) upgrade to F14 or F15 (if you upgrade to F14, add the virt-preview 
repo to your yum configuration (just copy 
http://repos.fedorapeople.org/repos/jforbes/virt-preview/fedora-virt-preview.repo
into /etc/yum.repos.d)

3) Decide that you maybe don't *really* need spice support, but that the 
VNC-based guest displays are adequate for your needs - this will work 
with the stock qemu-kvm on F13 and is just fine for most uses.
