Solaris LDOM创建

■1. 为控制域创建必须的服务，主要包括如下：
      ▶ vdiskserver ： 虚拟磁盘服务器
        a. 添加vdiskserver
           ldm add-vds <service-name> <ldom>
           ldm add-vds primary-vds0 primary # 控制域为primary
        b. 删除vdiskserver
           ldm remove-vds [-f] <service-name>
      ▶ vswitch ： 虚拟交换机服务器
        a. 使用ifconfig -a 查看网卡名称，如：net0
        b. 添加vswitch
           ldm add-vsw net-dev=<device> <vswitch-name> <ldom>
           ldm add-vsw net-dev=<网卡名称> primary-vsw0 primary
        c. 删除vswitch
           ldm remove-vsw [-f] <vswitch-name>
      ▶ vconscon ： 虚拟终端服务器
        a. 添加vconscon
           ldm add-vcc port-range=<x-y> <vcc-name> <ldom>
           ldm add-vcc port-range=5000-5100 primary-vcc0 primary
        b. 删除vconscon
           ldm remove-vcc [-f] <vcc-name>
      ▶ 查看控制域已有的服务
        ldm list-services primary
      ▶ 启动虚拟网络终端服务
        svcadm enable vntsd

■2. 为控制域分配系统资源
     a. 分配CPU
        ldm set-vcpu 8 primary
     b. 分配内存
        ldm set-memory 4096m primary
     c. 保存分配方案到SP中(service processor)
        ldm add-config <config-name> #创建新配置文件
        ldm add-config -r <autosave-name> #更新或创建配置文件
        ldm list-config # 查看已存在配置文件

■3. 创建客户域(虚拟机)
     ▶分配系统资源(CPU,内存，网络)
      a. ldm add-domain jvm_sol11
      b. ldm add-vcpu 4 jvm_sol11
      c. ldm add-memory 4g jvm_sol11
      d. ldm add-vnet vnet0 primary-vsw0 jvm_sol11
     ▶使用zfs卷作为虚拟硬盘
      a. zfs create -V 20g rpool/jvm_sol11
      b. ldm add-vdsdev /dev/zvol/dsk/rpool/jvm_sol11 sol11_vol@primary-vds0
      c. ldm add-vdisk sol11_vdisk sol11_vol@primary-vds0 jvm_sol11
     ▶为虚拟机分配虚拟光驱(ISO)
      a. ldm add-vdsdev /root/text_install_sparc.iso sol11_image@primary-vds0
      b. ldm add-vdisk cdrom sol11_image@primary-vds0 jvm_sol11
      c. ldm rm-vdisk cdrom jvm_sol11 #删除虚拟光驱
     ▶将分配的资源绑定到虚拟机
      a. ldm bind-domain jvm_sol11 # 绑定资源
      b. ldm unbind-domain jvm_sol11 # 松绑
      c. ldm list-bindings jvm_sol11 # 查看绑定信息
      d. ldm start-domain jvm_sol11 # 启动虚拟机
      e. ldm stop-domain jvm_sol11 # 关闭虚拟机

■4. zfs文件系统快照
     ▶创建销毁快照
      a. #将创建一个 tank/home/cindy 的快照，其名称为 friday
         zfs snapshot tank/home/cindy@friday
      b. #查看快照
         zfs list -t snapshot
      c. #销毁快照
         zfs destory tank/home/cindy@friday
      d. #重命名快照
         zfs rename tank/home/cindy@snap1 today
                                    <old> <new>
      e. #回滚快照,将tank/home/cindy回滚到friday快照
         zfs rollback tank/home/cindy@friday
      f. #查看两个快照差异
         zfs diff tank/home/tim@snap1 tank/home/tim@snap2
     ▶zfs克隆
      a. #创建克隆
         zfs clone tank/home/cindy@friday tank/home/cindy_clone
      b. #销毁克隆
          zfs destroy tank/home/cindy_clone
