xen-3.0.3-132.2.0.1.AXS3

This package contains the Xen tools and management daemons needed to run virtual machines on x86, x86_64, and ia64 systems. Information on how to use Xen can be found at the Xen project pages.
The Xen system also requires the Xen hypervisor and domain-0 kernel, which can be found in the kernel-xen* package.
Virtualization can be used to run multiple operating systems on one physical system, for purposes of hardware consolidation, hardware abstraction, or to test untrusted applications in a sandboxed environment.
Security issues fixed with this release:
CVE-2011-3346
No description available, see the CVE link below.
Fixed bug:
- Fixed the VIF hot-plug script so that the default MTU for new VIFs will match that of the target Xen hypervisor bridge. In combination with a new enough kernel (RHSA-2011:1386), this enables the use of jumbo frames in Xen hypervisor guests.
- Fixed the network-bridge script so that the the MTU of the bridge does not differ from that of the physical interface. This means the MTU can be higher than 1500, thus also providing support for jumbo frames.
- The recent migration procedure speeds up the migration of guests with large memory, but can theoretically cause data corruption. This update makes the xend daemon wait properly for correct device release before the guest is started on a destination machine, thus fixing this theoretical bug. Note: Before a guest is using a new enough kernel, the MTU of the VIF will drop back to 1500 (if it was set higher) after migration.
