Ubuntu 11.10: Xen vs. KVM vs. VirtualBox

While last week I showed how Ubuntu’s performance has evolved as a KVM guest from Ubuntu 8.04 through Ubuntu 11.10, in today’s article is a Linux virtualization showdown between VirtualBox, Xen, and KVM while using Ubuntu 11.10 on the Linux 3.0 kernel.

This Linux virtualization comparison is being done using a ZaReason notebook with an Intel Core i7 2630QM (Sandy Bridge) quad-core processor with Hyper Threading, 8GB of system memory, a 128GB Super Talent SSD, and NVIDIA GeForce GT 555M graphics. Ubuntu 11.10 x86_64 was used on the host with the Oneiric’s Linux 3.0 kernel, Unity 4.22.0, X.Org Server 1.10.4, GCC 4.6.1, and an EXT4 file-system. Each VM instance had access to all eight logical cores and 6GB of system memory.
