Sylvain:
progress! Almost there...
I changed the tap mac addr to 02:03:04:05:06:07. The arp is ok (VM#2 to
VM#1), on VM#2:
[norberto@vmGoes-fedora2 ~]$ arp -n
Address HWtype HWaddress Flags Mask
Iface
169.254.6.2 ether 02:03:04:05:06:07 C
p2p1
However, no reply ping is received in the origin (VM#2) :
[norberto@vmGoes-fedora2 ~]$ ping 169.254.6.2
PING 169.254.6.2 (169.254.6.2) 56(84) bytes of data.

The ICMP request packets flow by p2p1 interface at VM#2.
But no ICMP packtes captured the br0 (VM#1):
>>> tcpdump br0 on VM#1 (destination):
[root@vmGoes-fedora norberto]# tcpdump -i br0 -v
tcpdump: listening on br0, link-type EN10MB (Ethernet), capture size 65535
bytes
Please, do you have any suggestion?
Thanks.
