Hi let me answer to that !!
The image on that they try to instantiate is a raw image.
And they use and template that instantiate the immage as qcow2 .. i don't think is posible that. Why is that becase i personaly make the images .. but they don't listen me i already told the like 5 time .. your webinterface that instatiate the machine use as template qcow2 driver and that won't work. So for all to understand .. the Machine already run a bunch of VM's .. the only machines that won't work are they try instantiate trou RPC-xml from other webinterface.

Can you check if that file is accessible by oneadmin in the host machine?

    Thanks for suggestions. Checked the details from [1] and seems to
    be as it should.

    Hi,

    First make sure the required configuration [1] is in place.
    Then take a look at the libvirt log files, they may contain more
    information: /var/log/libvirt/libvirtd.log and
    /var/log/libvirt/qemu/one-<id>.log

        Hi everybody,

        I'm new here and you're my "The Last Stand" solution. What's
        the story:

        When I try to create a VM from my app, I receive this error:

        I have OpenNebula 4.2 on Debian, and I don't know where else
        to look for an answer.

        Thank you

        Marius
