CERN Openstack (super) User Story CERN is looking for answers to the fundamental questions concerning creation of the Universe and true to its nature, its a a big data challenge. With the historical run of LHC in 2013, their archive now contains ~100PB (with additional 27PB/year) at ~11 000 servers with ~75000 disk drives and ~45 000 […]
The OpenStack Summit is a five-day conference for developers, users, and administrators of OpenStack Cloud Software. This time it takes place in Palais des congrès in Paris from November 2 to November 7. ICCLab is attending the Openstack Summit for the very first time.

In our previous work we presented the performance of live migration in Openstack Icehouse using various types of VM flavors, its memory load and also examined how it performs in network and CPU loaded environment (see our previous posts –performance of live migration, performance of block live migration, performance of both under varying cpu and […]
Previously, we analyzed the performance of virtual machine (VM) live migration in different scenarios under Openstack Icehouse. Until now, all our experiments were performed on essentially unloaded servers – clearly, this means that the results are not so widely applicable. Here, we analyze how the addition of load to the physical hosts and the network […]
We continue our recent work regarding an analysis of the performance of live migration in Openstack Icehouse. Our previous results focused on block live migration in Openstack, without shared storage configured between computing nodes. In this post we focus on the performance of live migration in the system with a shared file system configured, compare […]
Since our servers have been set up for live migration with Openstack Icehouse, we wondered how live migration would perform. We measured the duration of the migration process, VM downtime duration and the amount of data transfered via the ethernet during a live migration. All tests were performed across 5 different VM flavors to examine the impact […]
[Update 8.12.2014] Since OpenStack’s Juno release hasn’t introduced any changes regarding live migration, Juno users should be able to follow this tutorial as well as the Icehouse users. If you experience any issues let us know. The same setup can be used for newer versions of QEMU and Libvirt as well. Currently we are using QEMU 2.1.5 […]
Vojtech joined the ICC lab through the IAESTE trainee programme. He’s completed his Masters study programme at the department of Computer science of the Technical University in Ostrava in Czech Republic. During his studies, he spent one year at Saimaa University of Applied Sciences in Finland participating in a double degree study program. His academic […]
