Hi,

could you please provide engine.log? And also vdsm.log from a host which was acting as a fence proxy?

At proxy host (kvm1) I see the following vdsm.log:

2020-12-15 10:13:03,933+0000 INFO  (jsonrpc/0) [jsonrpc.JsonRpcServer] RPC call Host.fenceNode failed (error 1) in 0.01 seconds (__init__:312)
2020-12-15 10:13:04,376+0000 INFO  (jsonrpc/7) [jsonrpc.JsonRpcServer] RPC call Host.fenceNode failed (error 1) in 0.01 seconds (__init__:312)

vdsm-client Host setLogLevel level=DEBUG

This should be executed on the host which acts as a fence proxy (if you have multiple hosts, then you would need to turn on debug on all, because the fence proxy is selected randomly).

Once we will have vdsm.log with fence_xvm execution details, then you can change log level to INFO again by running:

vdsm-client Host setLogLevel level=INFO

Thanks,

Martin

At engine I had set the fence agent mapping as below (and have restarted ovirt-engine service):

engine-config -g CustomFenceAgentMapping

Let me know if you need more logs.

I am running ovirt 4.3.10.

Thanks,

Fence_xvm requires a key is deployed on both the Host and the VMs in order to succeed. What is happening when you use the cli on any of the VMs ?
Also, the VMs require an open tcp port to receive the necessary output of each request.I

I deployed keys at the physical host and virtual hosts, as per https://github.com/rightkick/Notes/blob/master/Ovirt-fence_xmv.md

I can get the VM status from the virtual hosts:

[root@kvm1 cluster]# fence_xvm -a 225.0.0.12 -k /etc/cluster/fence_xvm.key -H ovirt-node0 -o status
Status: ON
You have new mail in /var/spool/mail/root
[root@kvm1 cluster]# fence_xvm -a 225.0.0.12 -k /etc/cluster/fence_xvm.key -H ovirt-node1 -o status
Status: ON

kvm0 and kvm1 are the hostnames of each virtual host, while ovirt-node0 and ovirt-node1 are the domain names of the same virtual hosts as defined at virsh.

I am passing also the port/domain option at GUI, but from logs it seems it is being ignored as it is not being logged from engine.

tried also domain=ovirt-node0 with same results.

Hi friends,

I was wondering what is needed to setup fence_xvm in order to use for power management in virtual nested environments for testing purposes.

I have followed the following steps:
https://github.com/rightkick/Notes/blob/master/Ovirt-fence_xmv.md

I tried also engine-config -s CustomFenceAgentMapping="fence_xvm=_fence_xvm"
From command line all seems fine and I can get the status of the host VMs, but I was not able to find what is needed to set this up at engine UI:


At username and pass I just filled dummy values as they should not be needed for fence_xvm.
I always get an error at GUI while engine logs give:
