[Resolved] Not able to create a more then one VM on OpenNebula

Hello,
I am setting up opennebula on two node cluster (One Head and one Worker node).
I have completed all the installation and configuration part, but stuck at VM creation.
My problem is that I am not able to create more then one VM. If I have one VM which is in running state, all the remaining will go to failed state.
log file for that:

One thing that I noticed is that, while VM creation is in prolog state and disk0 and disk1 are being made at /var/lib/one/datastores/0/vmname/, the failed VM’s are getting uid and gid = 99(i.e. nobody).
I think that’s what causing it to fail, as for the case of successful one, its’s uid and gid is first oneadmin then qemu.
Either that or that error in the log messages that says address already in use.

I have checked all the file permissions (actually gave all the files in /var/lib/one/, “u+rwx” permission).
And libvirtd is running on worker node.

Thank you.

I would suggest to check VNC configuration in your VM template. Maybe “VNC troubleshooting” section in that guide will help you.

Thanks a lot knawnd,
I disabled the VNC and the VM’s created just fine. Will try to configure VNC later on, but for now, my system is up and running. Thanks. :slightly_smiling:

Glad to help!

Just in case you haven’t already figured out, this is because two VMs using
the same VNC port, review the GRAPHICS section of your templates, specially
PORT.

Yes, I figured that out. That was the reason I was getting “Address already in use” error. Thanks any way Ruben. :slight_smile:
