This does not directly depend on Crossbow but on the NIU (Network Interface Unit) available on the UltraSPARC-T2 cpu. This provides the ability for a guest domain to directly access a physical network interface owned by an I/O domain. That way, unicast network packets can be directly sent/received by a guest domain to/from the outside world without going through the VSW. > *Virtual I/O dynamic reconfiguration* > > Sounds interesting, maybe someone could explain what is meant by this one? This is ability to add/remove virtual devices and services (vnet, vdisk, vds, vsw) without having to reboot a domain. For example, you can dynamically add/remove a virtual disk or a vnet to a guest domain without having to reboot it. Another major feature coming with 1.1 (not listed below) is cold and warm migration of guest domains. alex. > -- > Matt Walburn > http://mattwalburn.com > > > On Fri, Dec 19, 2008 at 3:06 AM, klarien <klarien at gmail.com > <mailto:klarien at gmail.com>> wrote: > > list of goodies i have un-officially collated > > 1. higher rev so it must be better - right :-) > 2. some new command flags (was -e in 1.0.3 - can't remember) > 3.
