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.
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.

Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
