There is some confusion around the OVA format that I'd like to clarify. OVA
is a very flexible format, in the sense that it's essentially an XML to
describe the VM, but the content within may be (and practically is)
whatever one feels like. A concrete example is a NIC - it can be (in
VMware's case) a vmxnet3 and in our case virtio-net driver. So the fact
there's a single XML that describes a VM has absolutely no assurance of an
interchangeability.
oVirt, via virt-v2v integration, took the additional step to actually
perform a conversion from VMware format and drivers and specs to KVM and
oVirt.

The other way is left as an exercise for the reader, I'm afraid.

The goal of this feature, among others, is to more easily share VMs and
templates between setups for example.
Y.
