Ajustes do XenServer

1) Primeiramente, vamos localizar nossa VM.

[root@xenserver ~]# xe vm-list

uuid ( RO)           : 6f81867d-9475-44e7-9573-8342583142bd
    name-label ( RW) : vlan002-ip249-pfsense
    power-state ( RO): running

2) Em seguida, vamos listar os vifs (placas de rede) da VM.

[root@xenserver ~]# xe vm-vif-list uuid=6f81867d-9475-44e7-9573-8342583142bd

uuid ( RO)                   : 1abe0b6f-d80f-d2f5-5b8e-dc50e51a5416
          vm-name-label ( RO): pfsense
                 device ( RO): 2
                    MAC ( RO): 5a:8e:34:98:34:98
           network-uuid ( RO): 187eda74-bf20-7503-aff0-2c04f285fe14
     network-name-label ( RO): LAN

uuid ( RO)                   : 0e16ce00-7da0-a5ff-09a1-0dc09fe3f5c1
          vm-name-label ( RO): pfsense
                 device ( RO): 1
                    MAC ( RO): c2:9a:67:9c:1d:12
           network-uuid ( RO): 59f92216-12a3-fba6-16f3-a4cd19ae436b
     network-name-label ( RO): WAN

3) Agora, para cada uuid de interface listado, é necessário executar os passos 4 e 5.

4) Configure uma variável para o uuid.

[root@xenserver ~]# export VIFUUID="uuid" (uuid=IDs listados no passo 2)

[root@xenserver ~]# echo $VIFUUID
1abe0b6f-d80f-d2f5-5b8e-dc50e51a5416

5) Agora, desative as configurações de transferência na interface.

[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-gso="off"
[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-ufo="off"
[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-tso="off"
[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-sg="off"
[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-tx="off"
[root@xenserver ~]# xe vif-param-set uuid=$VIFUUID other-config:ethtool-rx="off"

OBS: Não esqueça de repetir os passos 4 e 5 em todas as interfaces listadas no passo 2.

Agora vamos instalar o xen-tools no pfSense.

1) Instale o xe-guest-utilities no pfSense via SSH
