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. 1dae7037-73d5-4f11-b7da-c5d1a6aa36b7 # 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: 2017-01-21T01:06:37.145854Z qemu-kvm: -drive file=/rhev/data-center/00000001-0001-0001-0001-0000000002ad/6643dec0-12b2-4764-9473-a86975ef523d/images/1dae7037-73d5-4f11-b7da-c5d1a6aa36b7/17a57535-77d1-4b3f-a0b4-a6f9b7717b4a,format=raw,if=none,id=drive-virtio-disk0,serial=1dae7037-73d5-4f11-b7da-c5d1a6aa36b7,cache=none,werror=stop,rerror=stop,aio=threads: Could not open '/rhev/data-center/00000001-0001-0001-0001-0000000002ad/6643dec0-12b2-4764-9473-a86975ef523d/images/1dae7037-73d5-4f11-b7da-c5d1a6aa36b7/17a57535-77d1-4b3f-a0b4-a6f9b7717b4a': Permission denied Thread-2666080::INFO::2017-01-20 17:06:37,321::vm::1308::virt.vm::(setDownStatus) vmId=`a1257117-e3f8-4896-9ab4-1b010298f282`::Changed state to Down: internal error: qemu unexpectedly closed the monitor: (process:23124): GLib-WARNING **: gmem.c:482: custom memory allocation vtable not supported.
