Create Virtual Machine Failed

Hey,
I try to make a virutal Machine out of my template, but the status is allways “failed”.
I am completely new OpenNebula and not very skilled in Linux
This is the log:

Does anyone have suggestions for improvement?

Can you instantiate again, and when it fails, send the output of:

# in the hipervisor node
find /var/lib/one/datastores/0 -ls

Meanwhile I changed the settings in some places a litte.

the last part with libvirt-qemu libvirt-qemu looks wrong, right? :confused:

For OpenNebula, it will refer to /var/lib/one/datastores/0 but since you do symlink, in filesystem it will store at /mnt/nfs/datastores/0. In this case, i dont prefer to symlink. Have 2 options (what i have practice)

  1. Mount the external NFS to /var/lib/one/datastores instead of /mnt/nfs/datastores OR

  2. Add /mnt/nfs/datastores as DATASTORE_LOCATION & DATASTORE_BASE_PATH in oned.conf file

I agree with @anandharaj, it looks like a problem with the NFS configuration.

Another option would be to mount -o bind from /mnt/nfs/datastores to /var/lib/one/datastores in the hypervisor node.

Make sure you also have no_root_squash in your NFS configuration. By the way, does your /etc/libvirtd/qemu.conf say dynamic_ownership = 0?

Hey,

The problems could be solved.

file=/var/lib/one//datastores/0/10/disk.0,if=none,id=drive-scsi0-0-0,readonly=on,format=qcow2,cache=none: could not open disk image /var/lib/one//datastores/0/10/disk.0: Invalid argument

My template was set on raw instrad of qcow2 → Could not open disk

Thanks for your help :smile:

Btw: the symlinks were correct
