Of course, a microhypervisor is nothing without its userland. The NOVA
project is happy to announce that there is also a new prerelease of the
NOVA userland (NUL). NUL is available under the terms of the GPLv2. 

Prominent new features of the root partition manager are:

 - support for one-shot timers (HPET)
 - MSI and MSI-X support
 - direct assignment of PCI devices to VMs
 - IRQ routing discovery
 - SMP support
 - Intel 82576 network card driver
 - VESA VBE 2.0 support

New features of the VMM include:

 - APIC, IO-APIC, and MSI/MSI-X support
 - experimental SMP VM support
 - Intel 82576VF network card model
 - RTL8029 network card model

Additional information is available in the source tarball and at
