I am trying to take one of virtual appliances available on https://www.graylog.org/download.  I have the tried to import the VMware OVA through the ovirt GUI but it fails with "Failed to load VM configuration from OVA file: /tmp/graylog-2.1.2-1.ova".  /tmp/graylog-2.1.2-1.ova is the location of the file on the webclient.

So I try to use the openstack image. From my ovirt host:

# unzip graylog-2.1.2-1.qcow2.gz

# qemu-img info /tmp/graylog-2.1.2-1.qcow2
image: /tmp/graylog-2.1.2-1.qcow2
file format: qcow2
virtual size: 5.9G (6291456000 bytes)
disk size: 5.8G
cluster_size: 65536
Format specific information:
    compat: 1.1
    lazy refcounts: false
    refcount bits: 16
    corrupt: false

I create a VM in ovirt named graylog with a disk sized at 25 GB

I locate the the disk id that the VM graylog has in the ovirt GUI.

# qemu-img convert -O raw /tmp/graylog-2.1.2-1.qcow2 /rhev/data-center/mnt/blockSD/6643dec0-12b2-4764-9473-a86975ef523d/images/1dae7037-73d5-4f11-b7da-c5d1a6aa36b7/17a57535-77d1-4b3f-a0b4-a6f9b7717b4a

I then try to start the VM and get in both the vdsm.log and GUI:
