Description:

   The following vulnerabilities were fixed:

     CVE-2015-2752, bnc#922705)
   - Unmediated PCI command register access in qemu (XSA-126, CVE-2015-2756,
     bnc#922706)
   - Certain domctl operations may be abused to lock up the host (XSA-127,
     CVE-2015-2751, bnc#922709)

   The following non-security bugs were fixed:
   - xen dmesg contains bogus output in early boot (bnc#923758)
   - Xentop doesn't display disk statistics for VMs using qdisks (bnc#921842)

   The following functionality was enabled:
