Xen 4.1.1 maintenance release available

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.

    I have downloaded the newest xen via
    “hg clone http://xenbits.xensource.com/ext/debuggers.hg
    which include kdb, however ,when I used “make xen kdb=y debug=n” to compile it, there`s something wrong. The error is that :
    kdb_cmds.c:75: error:‘struct cpu_user_regs’ no such member named ‘xxx’
    What should I do to deal with these error ?
