      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?

                      and you confirmed in the DHCP server that the reservation is successful? I know sounds crazy - how could it even make a request to the LAN to get a DHCP address if it can't respond to the DHCP provider that it accepted it? But then if all of that works, then why can't you connect to resources on the the network for which you were provided an IP?

                        @Dashrender it must be the same, as my /etc/resolv.conf is the same in XenServer and in Centos

                          https://toic.org/blog/2008/multiple-network-interfaces-in-xen/
                          i read this but i do not have /etc/xen/scripts/network-bridge in xenserver 7

                            Hello guys,

                            sorry to bother you again,, but i just noticed something:
                            i have another xenserver host on my VirtualBox
                            and i can ping this other host from my guest vm inside xen host 1.. meaning:

                            Vbox = I
                            xenhost 1 = I.I
                            centos vm = I.I.I
                            xen host 2 = I.II
                            and centos can ping I.I0_1486584964528_flowchart.PNG

                            here is a picture for better understanding.. thannks

                                  Ping from Xen host 2 isn't working?

                                  Can you show us the networking picture? try rebooting the whole thing, shut down both XenServer 1 and 2, close Virtual Box, reboot PC, try again.
