When I create a virtual machine he status is forever "pending"

Hello everybody.
Okay !?

I am Brazilian and I apologize if I write something wrong.
I need a help to implement OpenNebula with academic objective (master).

I have a virtual machine (4GB RAM, 100 GB HD) as frontend using Centos7 and have two physical hosts (8GB RAM, 500GB HD) using Centos7 well.

I’m using version 4.8 OpenNebula.

Managed to create network, cluster, datastore, insert images and create templates …

I’m having problems when creating virtual machines, the status is forever “pending” and can not get more information in the logs. I’ve tried to create other datastores, use other images and the problem continues.

Could anyone help?

From already thank you very much.

hi Cesar,

the reason for the VM not being deployed can be found in /var/log/one/sched.log
This is where opennebula logs what happens when deploying a VM and deciding where it will deploy it. If you need more help, please post the log of a VM and the relevant part of the log from sched.log, so we can take a look at what happens.

hope this helps !

It’s solved. I copy again SSH key to host remote and restarted the nodes.

Thanks!!!

Hi Anton Zubkov,

In general, speaking with my experience with OpenNebula, a VM is in PENDING state when it is waiting for a resource to be available. It could be datastore, hypervisor host, CPU, MEMORY, etc.

So lets clear out issues one by one.

Please provide some more info about your setup - OpenNebula’s version, setup, configuration, resources, etc.

Kind Regards,
Anton Todorov
