Hi, all.
I tested some operations with libvirt 1.1 on Xen 4.3
Creating vm seems okay, but I cannot connect to its vnc console. So, I checked its
bining.
[root@dev-2 ~]# netstat -antp|grep 5900
tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN
10508/qemu-system-i
I tried several times, but it always binds 127.0.0.1 only.
here's my xml.

I tried both 0.0.0.0 and my public ip on the address attribute, and those didn't work
too.
Did I miss something?
Try dumpxml while it's running, you'll see what was parsed and all
current data. The following works perfectly for me. Check the cmdline
it is running with. If we pass it right then there is problem somewhere
else (but I doubt that this is the case).
<graphics type='vnc' port='5900' listen='0.0.0.0'/>
But I have to stress out this is definitely not what you want, moreover
without a password set. You can forward these ports through ssh,
connect with virt-viewer, etc. Without setting anything else than
127.0.0.1 to listen on
Hope this helps, have a nice day,
Martin
