So here's your problem. Your bridge in dom0 is NOT forwarding the packets out to peth0..



root@xen411dom0:/ftp/HVM# tcpdump -i eth0 'icmp[icmptype] = icmp-echo and
     icmp[icmptype] != icmp-echoreply'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 19:54:00.770442 IP 192.168.1.180> 192.168.1.1: ICMP echo request, id 518,
     seq 23, length 64
19:54:01.770958 IP 192.168.1.180> 192.168.1.1: ICMP echo request, id 518,
     seq 24, length 64

So where are these packets going to ? They're not getting out of dom0..

Do you have a firewall rule in dom0 that drops them?

Try these:
- In the HVM guest: run "arp -an" and check what MAC address you see for the gateway-IP. - In dom0: run "brctl showmacs eth0" and verify which port has the MAC of the gateway.

[root@centoshvm ~]# arp -an
? (192.168.1.102) auf 00:1c:25:7e:fb:b7 [ether] auf eth0
? (192.168.1.124) auf b4:99:ba:c1:27:36 [ether] auf eth0

So the HVM guest has NOT received a MAC address for the gateway..
so ARP requests are not working from the HVM guest.

Do this:
- Shutdown the VM.
- Start the VM.
- Run tcpdump in dom0 (tcpdump -i tap<x>  -nn)
- Try pinging the gateway from the HVM guest.
- Paste the whole tcpdump output here.

Are you running some firewall (iptables or ebtables) in dom0 ?
No. It is plane wheezy with 3.0.1 kernel
