            Ok, then it's probably something to do with DNS. What is in the /etc/resolv.conf?

              Or he actually said the Gately wrong in this machine. That he can ping it is not relevant it's in the subnet.

                I'm not sure what problem we're solving anymore. But the OP mentions the his Windows VM can't ping anything, and nothing can ping it. I would guess that maybe a subnet mask issue or vNIC issue.

                  @travisdh1 this is the output of /etc/resolv.conf
                  search mydomain
                  nameserver 192.168.10.1 (This is my gateway)

                      Well that sounds about right. I think the windows firewall by default doesn't allow the machine to be pinged.

                      Is everything working now?

                        @Dashrender nope, i turned off the firewall of windows guest vm, so the guests inside xen are at the same state.. my guess is that vbox does not allow it, and it's all because of nested virtualization...

                          Did you remember to allow promiscuous mode on VirtualBox? If you miss that nesting will break networking.

                              This sounds like a hypervisor setting issue.

                                I wonder if my diagram above is wrong..

                                Is your Windows VM a direct guest of XS or of virtualbox?

                                  @Dashrender windows vm is in vbox, as you cannot create windows vm's in xen nested in vbox because they require HVM mode

                                    Can't be on XS, no HVM possible. VirtualBox does not support nesting.

                                        where is it getting it's IP from? from the LAN DHCP server?
                                        can the VM ping your default gateway?
