Ever since virtualization was invented, it has been an elusive goal to achieve the benefits of virtualization without reducing performance. Most virtualization technologies, especially hypervisors that host complete virtual machines, have overhead that prevents virtual environments from running with native performance. Virtualization can also subject applications to the "noisy neighbor" problem, in which other applications on the same host consume shared resources and cause...

An update to the Oracle VM Server for SPARC Best Practices whitepaper was just published. This brings the paper up to date with references to the latest servers and pointers to the current documentation, and adds discussion for resiliency when using scale-out servers like the S7-2. Background A review: Oracle VM Server for SPARC provides virtual I/O in which guest domains perform I/O though virtual devices provided by service domains. This is similar in concept to how guest...

In preparing for upgrading our lab Private Cloud Appliance (PCA) to the new release 2.3.2 (more on that later, but read here first) I remembered that we had already introduced a feature called Storage Live Migration (SLM). That lets you live migrate a VM from one server to another, even when its virtual disks and metadata are on a local file system repository instead of the typical shared SAN or NAS storage resource which would be accessible to both source and target...
