Hello,
I have installed xen-3.2.0 and I cannot ping anything other than the
dom0. And dom0 can ping domU but domU can't ping anything else. Did I
miss something in the switch to 3.2? I have read where xenbr0 is no
longer needed is there something special I need to add to my vif =
statement in the config file?
Thanks for any help,
Jon
Horrible post, let me add some information. When I try to ping from domU
to a host on my network and running tcpdump, I see the request and
replies. But I never see them on domU and when I ctrl+c the ping it
reports 100% packet loss. Here is a sample of what I am seeing:
Ping from DomU to laptop on same subnet:
