SMBIOS 3.0 support in dmidecodean invention by jdelvare On February 12th, 2015, the DMTF released version 3.0.0 of the System Management BIOS Reference Specification. This update isn't just adding enumerated values to existing structures, as previous updates did. It is also introducing a new entry point format which allows for larger tables and structures. Support for this needs to be added to dmidecode. Additionally, reading the entry point and the table from /dev/mem is no longer possible on all systems, so some work is in progress to offer an alternative interface through sysfs. It would be great to finalize this and release a new version of dmidecode that would support both SMBIOS version 3.0 and this new kernel interface. |
Protect disk devices from concurrent use in the libvirt libxl hypervisor drivera project by jfehlig The libvirt qemu hypervisor driver has long supported protecting disk devices from concurrent use via libvirt's lock manager interface. Xen used to support the same functionality in the old xend toolstack, but dropped support in the new libxl toolstack. The Xen community decided, rightly so, that this functionality is best provided by a higher-level management tool, e.g. libvirt. This project aims to provide integration between libvirt's lock manager and the libxl hypervisor driver, essentially reintroducing support for disk device protection in the Xen management stack. |
