SmartOS is a good choice. They provide KVM and joyent opensource their SmartDataCenter https://github.com/joyent/sdc

so you can provision VM with API.

They are developing for LXC which will give you better performance in the future.

...Wait. Did you just say they're developing LXC? That is hilarious.

They're SmartOS! They're on the Solaris codebase! They've had containers since 2005! Literally before it existed, it had containers!

linc01n's comment was a little unclear. SmartOS isn't doing anything with the LXC protect. What SmartOS has done is revived the branded zones code from Sun for emulating Linux system calls. This means that you can run Docker containers on SmartOS as zones, as well as use dtrace, mdb and ptools on your Linux binaries. You can read up some more here:

I saw Bryan Cantrill's talk on that! It did sound neat.
