Xen-server for single-point failover High Availability (HA)

Create a new resource pool (the pool in this place is the server Xen-server pool)

Enter the pool name and add a new server for the pool, click Add New Server, add our installed XenServer (server1,server2,server3

IP is 192.168.26.213,192.168.26.214,192.168.26.215).

After adding success: (on Server1 we have installed two virtual servers and the storage device used for NFS shared storage)

Next select the Pool SSS and select the Highly Available Settings tab.

Open the Configure High Availability dialog box to set some parameters as needed, and then confirm the save.

The system will be detected with a high-availability configuration, and the system will be displayed after the automatic configuration is completed successfully:

Then we test:

Let's start by opening three command windows: Test with Ping to see how the virtual server is changing in Xen-server1.

The Server1,server2 network is first disconnected to observe changes in Xen-ctenter.

Then the server2 is disconnected and then observed:

Server success Transfer achieves high availability:

It is important to note that after recovering the Server1 and Server2 networks, the virtual server is not automatically transferred back to the original server server1 on Server3.
