Configurando rede xenserver via console/terminal

XenServer 4.1

With the release of 4.1 and later, the management of network configurations are now controlled by the XAPI and not done through manipulating the network configuration files.

1. From the command line interface (CLI), identify the Physical Interface (PIF) you want to set the IP address on:
   [root@xenserver-xxxxxx ~]# xe pif-list params=all
   uuid ( RO)                     : xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
                      device ( RO): eth0
                         MAC ( RO): 00:1d:09:08:85:0c
                    physical ( RO): true
          currently-attached ( RO): true
                         MTU ( RO): 1500
                        VLAN ( RO): -1
              bond-master-of ( RO):
               bond-slave-of ( RO): 
                  management ( RO): true
                network-uuid ( RO): xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
          network-name-label ( RO): Pool-wide network associated with eth0
                   host-uuid ( RO): 074bc1df-2560-4de8-9b8a-e483df1109c3
             host-name-label ( RO): xenserver-xxxxxx
       IP-configuration-mode ( RO): Static
                          IP ( RO): 10.217.130.3
                     netmask ( RO): 255.255.255.240
                     gateway ( RO): 10.217.130.1
                         DNS ( RO): 10.217.130.2
                 io_read_kbs ( RO): 
                io_write_kbs ( RO): 
                     carrier ( RO): true
                   vendor-id ( RO): 14e4
                 vendor-name ( RO): Broadcom Corporation
                   device-id ( RO): 167a
                 device-name ( RO): NetXtreme BCM5754 Gigabit Ethernet PCI Express
                       speed ( RO): 100 Mbit/s
                      duplex ( RO): full
             disallow-unplug ( RW): false
                pci-bus-path ( RO): 0000:04:00.0
                other-config (MRW):
2. Use the pif reconfigure command to set the values: [root@xenserver-xxxxxx ~]# xe –pif-reconfigure-ip DNS=x.x.x.x gateway=x.x.x.x IP=x.x.x.x netmask=x.x.x.x uuid= xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (enter the uuid of the PIF you want to reconfigure)
