illumos-kvm

SmartOS runs just fine on AMD CPUs. KVM support for AMD hasn't been merged to illumos-kvm yet (mostly just due to time), but you can do your own builds with it (https://github.com/jclulow/illumos-kvm/). But Triton containers don't run in KVM anyway. They run natively on the OS with no VM. So you can download and run Triton on AMD today, just as you can with Intel CPUs.

This is something we've been working to fix in the community! The good news is that most of the development and testing so far has been on an N36L-based Microserver, where the experimental AMD KVM support seems to work pretty well. There's a github repo -- https://github.com/jclulow/illumos-kvm -- and hopefully I'll get time soon to respin a current SmartOS ISO with the AMD-enabled bits.

Most things work on AMD64. In SmartOS, KVM was the major feature that didn't work on AMD64, but as they said in the faq, the community has been working on that. I can't currently find the testing ISO builds with that support, but here is at least one repo with KVM on AMD support: https://github.com/jclulow/illumos-kvm Joyent's original work is worse than just Intel only, it requires features found in Core iX and relate Xeon CPUs. This means it doesn't work on Xeon 5xxx chips that are getting affordable and it doesn't work on C2D chips that support VT-x. It sounds like AMD support is further along than supporting older Intel chips.
