FreeBSD has had Xen for a while. It's still lacking in a few area though. http://txrx.org/xen/ ZFS and DTrace are on Mac OS X Leopard, what's your point? There's QEmu, Parallels, VMware, VirtualBox, and Bochs, and the kernel sources are under an OSI approved license so it theorietically could be implemented on there too, but there's no point. Solaris needs Xen because VMware won't have anything to do with them, even though it's an enterprise product, Linux users are spoiled and have no technical advantages to grant the right to be spoiled yet they get a slew of other things first, it's all propoganda, liberal licenses and blind sheep driving the core projects, and they got multiple large companies worth more than Sun to chip in. PCI passthrough is hardly easily done, and as others replied, not a huge priority, I personally don't need it, and most people I know who use Xen on Linux don't even use it. The Xen port hasn't been in development for years like it has on Linux, give them a break. OpenSolaris has only been available since mid-2005, and hasn't been usable until 2006, they've come a long way, and there's many areas to address. Linux has had 16 years, and it took 12 to become somewhat viable, especially for general users. OpenBSD is just a rebranded NetBSD made dog slow. Point being, it'll all come in due time, if you need it now, just use the OS you need to get it done, live without ZFS if you have to, if Xen is so important to you. As for security, this is hardly the right place to put that, and you obviously don't know about any of the Solaris security technologies.
