We are pleased to announce the availability of the Xen 4.1.1
maintenance release, the first maintenance release of the Xen 4.1
series. The release can be downloaded from the download pages.
Xen 4.1.1 sports the following changes:
- Security fixes including CVE-2011-1583 CVE-2011-1898
- Enhancements to guest introspection (VM single stepping
support for very fine-grained access control)
- Many stability improvements, such as: PV-on-HVM stability
fixes (fixing some IRQ issues), XSAVE cpu feature support for PV
guests (allows safe use of latest multimedia instructions), RAS
fixes for high availability, fixes for offlining bad pages and
changes to libxc, mainly of benefit to libvirt
- Compatibility fixes for newer Linux guests, newer compilers,
some old guest savefiles, newer Python, grub2, some
hardware/BIOS bugs.
For those yet to make the jump to the Xen 4.1 series, we have
also made available Xen 4.0.2, a
maintenance release in the Xen 4.0 series making available a
subset of the fixes listed above.
