RHEL 7 beta test

Some highlights from RHEL7 beta, planing to put one to production asap.

• LIO kernel target subsystem - better storage support
• LVM2 replace LVM with support of thin provisioning
• No more 32 bits
• XFS and Btrfs!
• Swap memory compression
• Fast block devices caching slower block devices
• automate relocate processes and memory for NUMA performance improvement
• APIC virtualization
• Long list of kvm improvement, including hot plug vCPU
• rgmanager, luci, ricci, ccs replaced with pacemaker (about time...)
• ruby 2.0.0, python 2.7.5! It's almost latest and greatest now, but for how long?
• co-pilot, performance tools. I cann't wait to dive in
• chrony replace ntp
• firewalld is a dynamic firewall daemon
• OpenLMI (another puppet & chef altnative?)
• OpenSSH chroot shell logins
• Multiple required authentications
• Need learn how systemd works
• Gnome 3, with screencast support
• DM-Multipath improved performance
• linux container as another interesting lightweight replacement for kvm 
• tickless kernel (great for battery life, also less CPU interrupt)
