Re: [Xen-users] Seeing the IP addresses of domUs from dom0
strange ... here is what I can see on my Notebook:
[root@tivoli VM]# arp -n
Address HWtype HWaddress Flags Mask
Iface
172.20.0.2 ether 00:16:3E:6F:97:1B C
xenbr0
There is only one VM on it (172.20.0.2) and I can't see
the interfaces of dom0, because this system is connected
to the internet with a PCMCIA UMTS card (ppp) and the
onboard network interface is not activated.

The ppp interface has no MAC address ... so this is OK
I use NAT on it and I don't have access to the server in my
company at the moment ... maybe I was wrong ... I will have
a look at it tomorrow.
My "xm list --long" is in the attached file. It was to long to
add it to the mail.
I have also added the kernel configuration files of dom0 and
domU.
