Ubuntu11.10Xen, KVM, and VirtualBox

Recently, some foreign users used Ubuntu11.10 to compare and test different Linux virtualization methods of VirtualBox, Xen, and KVM. This test uses a ZaReason laptop with Intel Core i000030qm (SandyBridge) quad-core processor installed and hyper-threading supported. It is equipped with 8 GB memory and gbssd and NVIDIAGeForceGT555M graphics card. Ubuntu11.10x86-64 is installed on Oneir

Recently, someone abroad has used Ubuntu 11.10 to compare and test different Linux virtualization methods of VirtualBox, Xen, and KVM. This test uses a ZaReason laptop with Intel core i7 2630QM (Sandy Bridge) quad-core processor installed and hyper-threading. It is equipped with 8 GB memory and 128 gb ssd and NVIDIA GeForce GT 555M graphics card, ubuntu 11.10 x86-64 is installed in Oneiric Linux 3.0 kernel, Unity 4.22.0, X. org Server 1.10.4, GCC 4.6.1, and EXT4 file system hosts. Each Virtual Machine instance is set to 8 logical cores and 6 GB memory.

Test Platform (click the picture to see the big picture)

VirtualBox 4.1.2, KVM, and Xen 4.1.1 are all installed on Ubuntu Oneiric. Ubuntu 11.10 also proves that Xen virtualization supports the DomU client. However, although Xen can now be used in Ubuntu, Canonical still regards KVM as the main Linux virtualization technology and continues to support it. VMware's Linux virtualization was not mentioned in this test, mainly because restrictions on use conditions may affect the benchmark test.

In addition to the benchmark tests for VirtualBox, Xen, and KVM, we will also announce benchmark tests for the Sandy Bridge System on bare metal for reference.

C-Ray multi-thread Operation Test

First, we use C-Ray to test the multi-thread computing performance. We can see that KVM Virtualization has superior computing performance. The KVM client instance can handle multiple threads at a bare metal computing speed of 91%, while the VirtualBox and Xen DomU clients on Sandy Bridge perform operations at a speed of 85% and 68% respectively.

POV-Ray rendering Test

POV-Ray 3.6.1 is a single-threaded and image rendering testing tool, with KVM leading performance. The rendering speed of KVM is almost the same as that of the Linux 3.0 kernel Sandy Bridge laptop bare metal. Followed by VirtualBox, Xen is far behind.
