I am testing ovirth, my test environment are:

Host: nested virtualization ESXi5.5+CentOS 6.4_x86_64

Guest: Ubuntu14.04_i386

Now, ping

CentOS <-> guest and outside are OK

Outside <-> gest Fail

I am using bridge connection, I try to tcpdump

[root@centos vdsm]# brctl show
bridge name                bridge id                       STP enabled     interfaces
;vdsmdummy;             8000.000000000000       no

                                                                                            vnet0
[root@centos vdsm]# brctl showmacs rhevm

[root@centos vdsm]# service iptables stop
[root@centos vdsm]# tcpdump

11:34:59.267379 ARP, Request who-has GUESTIP tell OUTSIDEPCIP, length 46
11:34:59.268017 ARP, Reply GUESTIP is-at 00:1a:4a:0c:14:41 (oui Unknown), length 28

I can see only arp working, how do I check this problem? and how vdsm convert from FE:1A:4A:0C:14:41 to guest mac 00:1a:4a:0c:14:41?

Thank you!
