"Joyent Announces SmartOS With KVM: An Open Source, Modern Operating System"
KVM on SmartOS provides entrepreneurs and enterprises highest performance
and profit potential through best of breed cloud technologies
August 15, 2011
"... today announced that it has ported KVM to its operating system,
SmartOS. SmartOS turns any server into a highly efficient,
multi-tenant application hosting platform. The open source project
offers innovative tools for application developers looking for
reliable, resilient storage and efficient virtualization that
Joyent has tuned and hardened for modern, data-intensive real-time
(DIRTy) application deployment."
※このプレスリリースでは Illumosについて触れてません。

SmartOS: The Complete Modern Operating System
"SmartOS incorporates the four most revolutionary OS technologies of
the past decade - Zones, ZFS, DTrace and KVM - into a single operating
system,"
OSes Booted under SmartOS Native KVM…to date
SmartOS 64-bit, Linux 64-bit, Windows Server 2008 R2, FreeBSD 8.1 32-bit
Plan 9 from Bell Labs, Seventh Edition, FreeBSD 4.9, Haiku OS, OpenBSD

WTF is SmartOS? (Page 1)
As an illumos derivative, has several key features:
ZFS:
DTrace:
OS-based virtualization (Zones):
Network virtualization (Crossbow):
Enhancement: OS Virtualization (Page 22)
*)illumos has deep support for OS virtualization
*)While our implementation does not require it, we run KVM guests in
a local zone, with the QEMU process as the only process
*)This was originally for reasons of accounting
*)...but given the recent KVM vulnerabilities, it has become a matter
of security
Enhancement: Network virtualization (Page 23)
*)We create a virtual NIC (VNIC) per KVM guest
Enhancement: DTrace, cont. (Page 27)
*)Orthogonal to this work, we have developed a real-time analytics
framework that instruments the cloud using DTrace and visualizes
the result

これだけ DTraceを前面に出しているのだから、標準と期待しています。

"Son of Solaris raids Linux for KVM hypervisor"
Joyent erects 'first major hypervisor' in half decade
15th August 2011, The Register
"In essence, KVM is running as a process inside the SmartOS containers,
Hoffman says, allowing the hypervisor to tap the plumbing the company
has already built into the operating system. "KVM looks like a process
on SmartOS, so you can take a normal operating system and you can run it
as a virtual machine and you can take advantage of everything you do
with command and control around a process.""
Hoffman, the Founder and Chief Technology Officer of Joyent,
"Joyent Open Sources SmartOS for the Cloud

Six Data Centers in North America
"Joyent, which received an infusion of funding from Intel in 2009,
runs six data centers in North America with a client mix that
includes large enterprises in the gaming, media, mobile and
e-commerce sectors. It sells software, SmartDataCenter, that runs
entire data centers."
