More press to our work
New: Our tech report received 10,000 hits in just the month of May. See a screenshot of stats below. Yay!
Our recent tech report on performance evaluation of Xen vs. OpenVZ is generating quite a buzz. It’s the second most viewed tech report from outside HP. Virutal strategy magazine picked up on it and wrote an article. A few people including Simon Cosby, CTO of Xensource responded. Slashdot picked it up yesterday. I am pleasantly surprised that there is not much FUD generated by the Slashdot readers in the comments. Some of the comments are quite informative. Virtualization.info and OpenVZ blogs have written about it too.
Let me point out a few facts straight away. Both technologies have their place. Xen trades off performance for security and isolation and if you want to run multiple operating systems Xen or VMware is the only way. OS level container technologies like OpenVZ beat these hypervisor-based technologies easily on performance, but they may not be appropriate for some situations.

See my howto on setting up Xen4 + pvops 2.6.32.x first before following this. Do steps 1, 2 and 3 described in the howto Install Xen 4.0.1 from GITCO repository. The benefit of this is that all the required packages, Xen enabled Linux kernel (2.6.18) and libvirt are correctly installed and setup wget http://www.gitco.de/repo/GITCO-XEN4.0.1_testing_x86_64.repo yum

Setting up Xen4 has been tricky, because of the move to the latest Linux kernels with paravirt_ops. Compiling it on CentOS, which uses 2.6.18 kernel, and old toolset is a bit more challenging. The following are my notes for setting up Xen4 + pvops 2.6.32.x on CentOS 5.5 on BL460c blades. Important note: I couldn’t

I have been pretty lazy about blogging, partly because I wanted to write really thoughtful posts like Richard Lipton does, but it is really difficult to write long interesting essays. So, I have decided to take the easy way out in the 140 character Internet world. I am going to list three very recent papers

Virtualization is a hot topic for research, and with the rise of cloud computing, it has gained even more attention. Great number of research papers are being published in many major conferences. The following is an attempt to list some of the research work, and how they influenced real products or features. Some of the

What is a client hypervisor? Client hypervisors are hypervisors that run on a user’s (client’s) desktop. A nice video showing Xen Client Hypervisor should clarify its usage. Server hypervisors like VMware’s ESX server, and XenServer virtualize a physical server that allow you to run multiple virtual machines. This has many benefits including reduced costs due

Introduction In virtualization community, live migration of virtual machines is pretty much considered a “default” mature feature in any hypervisor product. All major vendors like VMware, XenSource/Citrix, and Microsoft have products that support live migration. I consider it a major success for virtualizaton research community, since the first academic paper on it was published not
