一、设置pool自动启动

1. 查看pool的uuid

# xe pool-list

[root@xenserver-200 ~]# xe pool-list
uuid ( RO)                : 2b8555d7-2712-0125-36d5-c34958e2d75e
          name-label ( RW): 
    name-description ( RW): 
              master ( RO): 93e1b8ca-615d-4018-a6a0-28ac0e01b97e
          default-SR ( RW): <not in database>

2. 设置pool自启动

[root@xenserver-200 ~]# xe pool-param-set uuid=2b8555d7-2712-0125-36d5-c34958e2d75e other-config:auto_poweron=true

二、设置虚拟机（VM）自动启动

1. 查看vm的uuid

# xe vm-list

[root@xenserver-200 ~]# xe vm-list
uuid ( RO)           : c0372ee2-027e-890d-f016-2420eac7477a
     name-label ( RW): Windows Server 2008 R2 (64-bit) (1)
    power-state ( RO): running


uuid ( RO)           : 28c3c8c9-984f-4f82-9bab-b54563a01943
     name-label ( RW): Control domain on host: xenserver-200
    power-state ( RO): running

 2. 设置vm自启动

[root@xenserver-200 ~]# xe vm-param-set uuid=c0372ee2-027e-890d-f016-2420eac7477a other-config:auto_poweron=true

可以重启xenserver查看效果了。
