        You also need to configure Xen to bridge the connections to its VMs as well, so that your XenVMs will get IP addresses on your LAN as well.

            I don't have a XenServer in front of me to figure it out. Maybe @DustinB3403 can help?

              You don't need to configure XenServer to do that for you when the management interface is on the same network as the rest of the network. Since we're nowhere near best practices here anyway, it should just work. Why it's not I don't know, might have to do with the nested virtualization layers.

                Try some of the other VB options for networking.

                I have a MINT VM set up in VB. Two actually. Same, but with different options for home and work.

                  can the XS itself ping the internet or your local network?

                    yes of course, i downloaded all my iso-s from xenserver. i turned off iptables, but nothing.. is there something else that could block VMs traffic outside the XenServer.. i have not found anything so far.

                      the host firewall could be doing it.. not expecting the IP of the VM.
                      Turn off the host firewall for a test.
                      i.e. your windows desktop firewall (assuming you're running windows)

                        i gues if it is not expecting the trafic, it would not allow me even in virtualbox having traffic

                          No, that's not necessarily true. VirtualBox could have registered itself with the host firewall and the first IP it got. Sure I tend to agree this seems unlikely, but I'm reaching in an effort to find solutions.

                            The IP addresses of your VMs in XenServer -- are they getting IP addresses from your LAN as well?

                              @BRRABill only bridge network does the job, as it allows dhcp. with other network formats im not able to give ip to my guest vm's inside xen

                                  From one of your VMs:

                                  ping LAN IP of XenServer host.
                                  ping LAN IP of VirtualBox host.
                                  ping LAN IP of another system on your LAN that is not your VirtualBox host
                                  ping LAN IP of your router.

                                  Let us know which ones work and which ones do not.

                                    Is the VM getting DHCP? or did you manually assign the IP?

                                        don't - see if it will get a DHCP address from your LAN

                                          Please confirm that from the XS console that you can ping say 8.8.8.8.

                                          Where do you have XenCenter installed? on your local windows desktop?
