- okvm – Open source KVM over IP technology – The okvm project team in 2005 developed an open source okvm KVM Development Kit – so engineers could cost effectively roll their own integrated KVM over IP control appliances. These okvm KVM Development kits included: one okvm PCI KVM Adapter card the okvm KVM over IP software source code the source information needed to manufacture the okvm PCI KVM Adapter card (circuit diagrams, BOM,PCD layout etc) A number of the KVM PCI cards were produced – sponsored by Opengear. However this project did not find traction in the developer community. So kits are no longer available and development in this branch of the project has stopped. Also Opengear now sells a proprietary KVM over IP solution!

- Riemann – A network monitoring system – Riemann aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception raised by your code. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward to Graphite. Send alerts when a key process fails to check in. Know how many users signed up right this second. Riemann provides low-latency, transient shared state for systems with many moving parts.

- Using KVM virtualization – Kernel Virtual Machine (KVM) virtualization has largely replaced Xen as the default open source mechanism for creating and supporting virtual machines (VMs) on most Linux systems. Though the motivation for this change is primarily build and support related rather than technical, the reality is that many enterprise IT groups that are interested in virtualization will need to learn the administrative command-and-control tools that KVM uses. Similarly, IT shops with an existing investment in Xen virtualization that are moving to KVM will probably want to convert existing VMs to the formats that KVM supports whenever possible, rather than having to re-create them.
- Create Linux and Windows images for OpenStack private clouds – This article proposes a new way to construct Linux® and Windows® images for private clouds built with the OpenStack cloud operating system. Current image-creation methods for OpenStack environments are cumbersome and time-consuming. The authors present an online, self-service method that makes image construction faster and easier for operators and end users of private clouds.

- Centralizzare i log mediante Elasticsearch, Logstash e Kibana – Mia mamma usa Linux! – Uno dei principali problemi che si rilevano in fase di debug delle anomalie relative ad applicazioni è la frammentazione delle informazioni. Tanti log, buona parte dei quali inutili, sono sparsi ovunque nelle macchine interessate all’erogazione di questo o quel servizio.
Tipicamente quando si tratta di servizi ripartiti su più macchine è sempre necessario aprire diverse console all’interno delle quali, per ciascuna macchina, il (o i) file di log vengono aperti, filtrati stampati e via così, sino ad ottenere una situazione degna di Sherlock Holmes, in cui solo consumati ed abili detective riescono a trovare l’indizio che sfugge ai più.
Esiste però una via migliore per gestire enormi quantità di log in una forma centralizzata, facilmente ricercabile e che usi un’interfaccia gradevole. Si tratta della combinazione di tre software: Elasticsearch, Logstash e Kibana.
- Seminario “Evoluzione della virtualizzazione su Linux”: video uno e due – “Introduzione” e “Virtualizzazione” – Mia mamma usa Linux! – Nella giornata del 29 giugno 2012, presso l’hotel Holiday Inn di Rho si è svolto il secondo seminario di miamammausalinux.org, intitolato quest’anno “Evoluzione della virtualizzazione su Linux“.
Viste le numerose richieste ricevute e rispettando sempre la filosofia alla base del progetto miamammausalinux.org, il video del seminario viene proposto integralmente nelle sue parti, insieme alla documentazione fornita ai partecipanti.
Ecco le prime due parti.
