Yeah, we don't respect the allocation policy when importing from OVA [1]

Adding to the above that we don't want to change the format within the OVA because we wish to preserve sparseness

Verified:
ovirt-engine-4.5.0.5-0.7.el8ev
vdsm-4.50.0.13-1.el8ev.x86_64
qemu-kvm-6.2.0-11.module+el8.6.0+14707+5aa4b42d.x86_64
libvirt-daemon-8.0.0-5.module+el8.6.0+14480+c0a3aa0f.x86_64

Verification scenario:
1. Export VM with preallocated disk as OVA.
   Import OVA, select preallocated policy in import dialog.
   Verify VM imported, verify disk policy is preallocated.
   Run VM and verify VM is running properly.
2. Export VM with thin provision disk as OVA.
   Import OVA, select preallocated policy in import dialog.
   Verify VM imported, verify disk policy is preallocated.
   Run VM and verify VM is running properly.
3. Export VM with preallocated disk as OVA.
   Import OVA, select "auto detect" policy in import dialog.
   Verify VM imported, verify disk policy is preallocated.
   Run VM and verify VM is running properly.
4. Export VM with thin provision disk as OVA.
   Import OVA, select "auto detect" policy in import dialog.
   Verify VM imported, verify disk policy is thin provision.
   Run VM and verify VM is running properly.
