Red Hat Enterprise Linux 6.6 released
Yesterday Red Hat released another update of its Red Hat Enterprise Linux major release 6: 6.6. Like for the minor updates before many optimizations and some "technical previews" were implemented.
The changes have been documented well in the release and technical notes:

Beside common kernel driver updates some other interesting customizations were made - I'd like to list some of those:
- Installation as Hyper-V second generation VM - e.g. under Windows Server 2012 R2 (*), this also includes new Hyper-V Daemons: Hyper-V KVP (Hyper-V Key Value Pair) Hyper-V VSS (Hyper-V Volume Shadow Copy Service)
- Improved support of additional SCSI signals for better hardware change handling using
udev
(e.g. size changes, thin-provisioning status, adding new LUNs,...) - Implemented a Open vSwitch module for additional Red Hat products, support is only offered in combination with other Red Hat products
- For device mapper a caching modul (
dm-cache
) was introduced (*). This module can use faster drives (e.g. SSDs) as cache for slower storage media - details can be found in thelvmcache
manpage - The software packages

- System Security Services Daemon (SSSD) was optimized for better authentification in combination with Microsoft Active Directory
