"We used the same system as last time, which consisted
of an Intel Core i7 920 CPU (during our virtualization testing we
were running it at 3.60GHz), an ASRock X58 Super Computer
motherboard, 3GB of CSX DDR3-1600MHz memory, a 320GB Seagate
ST3320620AS hard drive, and a NVIDIA GeForce 9800GTX graphics card.
The host operating system and guest operating systems were Ubuntu
9.04 using the x86_64 architecture with the Linux 2.6.28 kernel,
GNOME 2.26.0, X Server 1.6.0, GCC 4.3.3, and the default EXT3
file-system. "For the KVM (Kernel-based Virtual Machine)
virtualization we were using virt-manager and had allowed the
virtual machine to have access to all eight logical CPU cores and a
maximum memory capacity of 2.5GHz. For our VirtualBox testing we
had installed Sun's xVM VirtualBox 2.1.4. This testing had started
prior to the release of VirtualBox 2.2, but afterwards we went
back, tried out VirtualBox 2.2, and found it in these benchmarks to
perform about the same speed as the earlier 2.1.4 release. As
Canonical dropped the dom0 kernel support with Ubuntu 8.10 and
later, Xen virtualization was left out of testing."
