Enhancements
————
A technical overview that describes the major enhancements can be found at:
http://www.redhat.com/rhel/server/resource_center/
+ Support for up to 126 CPUs in the x86_64 Xen-based
Hypervisor (up to 32 CPUs per virtual server)
+ Support for up to 1TB memory per host on x86_64
(up to 80GB per virtual server)
+ Increased number of dynamic IRQs for x86_64 to allow for
more guests on large systems
+ Support for more than 16 disk devices per guest
+ Added Virtio drivers for use of Red Hat Enterprise Linux 5
as a guest on KVM-based hypervisors
+ Automatically determine correct parameters for large memory
machines. The domain 0 is automatically restricted to 32GB,
but the hypervisor sees the full amount of memory in the
machine
+ Support for Intel Extended Page Tables (EPT) which delivers
higher performance in Fully Virtualized environments
+ Support for 2MB backing page tables on x86_64
+ Support for more than 4 NICs per guest

to provide crash with needed address

+ Added Intel VT-i2 support for new ia64 processor
+ Fixed lengthy network outage after live migrations
+ Xen log file rotation
+ Xenstore database moved to tmpfs
+ Xen paravirtualized drivers included for fully-virtualized
