Hi, is there any possibilities to import VM from VirtualBox to XO?

I have installed Xen Orchestra from source. Exported ova file v.1 (also v.2) from VirtualBox. But when I imported it (XO: Import > VM) after few minutes of loading (12%) Xen Orchestra say "VM import failed" and "See Log" but in XO log is nothing.

How to import VM from VirtualBox?
