虚拟平台环境：
需求做到异地虚拟机迁移验证。
目前部署情况：
1.vCenter server 部署了两套，部署位置不再同一地点。
2.两套独立本地vCenter server架构搭建完后，A位置数据中心平台管理vlan与B位置数据中心
平台管理vlan通过路由打通，在A机房和B机房管理地址能够互访。
3.为了测试，在A位置机房分别添加A机房ESXi-host和B机房ESXi-host，添加进数据中心。（
不在一个集群）
4.分别在A位置创建了2个分布式交换机，一个为distributed-A:添加A位置的ESXi-host
manage-vlan 20 VMkernal-migration-vlan 30
另一个为distributed-B:添加B位置的ESXi-host manage-vlan和VMkernal-migration-vlan 同
时使用 vlan 200
5.在VMotion迁移EXSi-host下的虚拟机时失败：
提示当前已连接的网络接口“Network adapter:"使用不可访问的网络"Distributed Virtual
Switch"
分布式交换机中的VMotion是一个二层vlan，内部通信vlan，需要怎么样才能使虚拟机能够迁
移，请大家帮忙解答。

Virtual platform environments:
Offsite virtual machine migration needs verification.
Current deployment:
1.vCenter server deployed two, deployment location is no longer the same place.
2. two independent local vCenter server infrastructure to build after the
management VLAN data center platform a and b Data Center Platform management VLAN
through routes opened up, in room a and room b administration addresses to
exchange visits.
3. in order to test, in a room ESXi-host room ESXi-host room were added a and b,
and added to the data center. （Not on a cluster)
4. separate 2 were in a position to create a distributed switch, one for the
distributed-A: adding a location ESXi-hostmanage-vlan 20 VMkernal-migration-vlan
30.Another distributed-B: add b, ESXi-host manage-VLAN and VMkernal-migration-vlan
Using VLAN 200
5. in the failed virtual machine VMotion migration EXSi-host:
Prompting the currently connected network interface "Network adapter:" the use of
an inaccessible network "Distributed VirtualSwitch"
VMotion is a two-story in a distributed switch VLAN, VLAN internal communication,
you need to do to enable the virtual machine to move
Move, please help me to answer.
