In less than two months Sun xVM VirtualBox version 2.x has undergone the third minor revision and VirtualBox 2.0.4 has been released.
As a long time VirtualBox user, I'm pleased to see this product evolve. I'm running Debian 4.0 testing, Ubuntu 8.10, Windows Server 2003 and Windows XP on a Solaris Nevada (b101 actually) guest on an HVM capable machines and it's a long time I'm not experiencing any problem during my daily life with VirtualBox. And now that version 2.x introduced support for 64 bits kernels, I think I'm not going to install a brand new image in a very long time: I have a backup of a snapshot of the Virtual Machines in a ZFS snapshot and whenever I rollback or clone an image, it's a no-brainer 5 minutes work.
The product covers almost 100% of my needs: the only thing I would really like to see in VirtualBox is audio input support for Solaris guests.
Looking forward to see Sun xVM server released: http://xvmserver.org/.
