I'm attempting to fine-tune the process of getting my KVM/Libvirt

OVF, it may be corrupted". I've attached both engine and vdsm logs
that are a snapshot from when I ran the virt-v2v command until I saw
the failure under Events.
matt - any thoughts?
Nothing springs to mind immediately, but it sounds like v2v is
producing

invalid OVF. If somebody can diagnose what the problem with the OVF is

fix v2v.

virt-v2v command used...
# virt-v2v -i libvirtxml -o rhev -os
dc-vmarchitect.tamu.edu:/exportdomain dh-imager01.xml
dh-imager01_sys.qcow2: 100%
[===========================================================================================================================================================================================================]D
0h00m37s
virt-v2v: dh-imager01 configured with virtio drivers.
The xml has been modified numerous times based on past mailing list
comments to have VNC and Network information removed, but still the
same failure. I've attached the latest XML that was used in the
log's
failure as dh-imager01.xml. I've also tried passing hte bridge
device
(ovirtmgmt) in the above command with same failure results.
Node and Engine are both CentOS 6.2, with vdsm-4.10.0-4 and
ovirt-engine-3.1 respectively.
Please let me know what other configuration information could be
helpful to debug / troubleshoot this.
Are there any other methods besides a virt-v2v migration that can
allow me to use my previous KVM VMs within oVirt?
Thanks

Attached is the virt-v2v generated ovf that's in my NFS export domain
Any other means to get KVM/libvirt/virt-manager based VMs into oVirt?
Possibly something as crude as provisioning new VMs with oVirt then
replacing the virtual hard drives?
this would work - just create the VM on an NFS storage domain with a disk
the same size as origin, and copy over the disk you had.
a bit trickier for iscsi, so i'd do this with nfs.
Thanks

Why is it trickier with iSCSI? Currently the only Data Center I have
functioning in oVirt only has iSCSI storage available.
with iscsi, you will have to create the disks as pre-allocated, and use DD
to overwrite them.
NFS doesn't have to be pre-allocated.
and since you are using pre-allocated, you need to use the RAW format iirc
Currently most of my KVM VMs are qcow2, so converting them to raw
would not be a problem. However, why is DD necessary? Why can't I
overwrite the <image_name>.img with my *.img file ? Since I've used
mostly qcow2 in my time with KVM/libvirt I may lack some understanding
of how to correctly handle raw images.
in both cases there aren't any .img files.
you can convert you qcow2 to raw before copying them over to iscsi or
nfs using qemu-img convert.
it is not necessary, but will save you failing on small details between
the two.
using the export domain is safest, even though it doubles the amount of IO
Would a qcow2 image with preallocation=metadata be possible on an
iSCSI data store?
ayal?
