Beyond Microbenchmarks: breakthrough container performance with Tesla efficiency
Back story As virtualization was beginning it's march to prominence, we saw a phased approach to adoption. This is common with any sort of game changing technology....let's take electric cars as an example. Early adopters are willing to make certain trade-offs (short range) to gain new capabilities (saving money at the gas station). In the meantime, engineers are off in the lab working hard to increase the possible consumer-base for electric cars by increasing range, decreasing charging cycle times, and...

Extending Red Hat Enterprise Virtualization with Vdsm hooks
oVirt is an open source management system for KVM -powered virtual machines. Red Hat Enterprise Virtualization (RHEV) derives from oVirt in the same fashion that Red Hat Enterprise Linux is derived from Fedora. oVirt's (and RHEV's) central management component, called oVirt-Engine, is written in Java and runs on top of JBoss. Engine controls dozens of nodes that may run many dozens of VMs each. Besides sounding like an improper innuendo when pronounced by Spanish-speaking people, "Vdsm" is Engine's per-node agent...
