I am from Veertu. We don't have GPL code in our hypervisor. We have BSD And LGPL, and if you are interested in the source code, we are in the process of open sourcing our core hypervisor.
As part of the process of open sourcing the core hypervisor we are updating the site with the lgpl library sources.
It's about time, Veertu has been using a lot of LGPL code without attribution or any visible attempts to comply with LGPL license requirements for the many components used.
Hopefully you guys did a true clean room implementation of the GPL components of QEMU.
