It raises JSON-RPC error.

Subject: [ovirt-users] How to configure Power Management Fence Protocol for Libvirtd VM ?

 

Hi, everyone:

 

My test env is running on Ubuntu Libvirtd server, I configure the QEMU VM as Physical Host, the hosts list is:

 

root@ubts1:~# virsh

Welcome to virsh, the virtualization interactive terminal.

 

Type:  'help' for help with commands

       'quit' to quit

virsh # list

Id   Name        State

---------------------------

24   3.ooengh1   running

25   3.ooengh2   running

 

 

root@ubts2:~# virsh

Welcome to virsh, the virtualization interactive terminal.

 

Type:  'help' for help with commands

       'quit' to quit

virsh # list

Id   Name       State

--------------------------

26   3.ohost1   running

27   3.ohost2   running

28   3.ohost3   running

 

The ooengh1 and ooengh2 are configured for hosted-engine, and ohst1 ohost2 ohost3 are configured for KVM server.

 

Now, I want to test the Power Management service using my test env, how can I choose the fence protocol ?
