Hi,
The NOVA project is happy to announce that there is a new prerelease of the NOVA microhypervisor available for download at http://www.hypervisor.org/ under the terms of the GNU General Public License version 2.
NOVA is based on a modern microhypervisor written in C++ and assembler. The current implementation runs on multi-core x86 machines that support ACPI, under QEMU (including VM support), and as a microkernel in a virtual machine on top of itself.
NOVA makes use of hardware virtualization features such as Intel VT-x/VT-d or AMD-V, and facilitates running unmodified guest operating systems in virtual machines with near-native performance.
Among other things, the new prerelease improves the security of device- and interrupt assignment by using capabilities for these operations. There is also a new hypercall for interacting with the scheduler.
At the same time, we've released a new version of the NOVA Userland (NUL). While there are few user-visible changes, a lot has changed under the hood. We have integrated a central admission server that is going to implement global policies for CPU time distribution in a future release. Another notable development is rudimentary libvirt support, which will eventually replace the old configuration syntax.
Cheers,
- Udo
