qemu-kvm-0.12.1.2-2.415.AXS4.4

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.

Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

Security issues fixed with this release:

• CVE-2013-4344

Buffer overflow in the SCSI implementation in QEMU, as used in Xen, when a SCSI controller has more than 256 attached devices, allows local users to gain privileges via a small transfer buffer in a REPORT LUNS command.

Fixed bugs:

• Fixed smart card emulation with MS Windows guests versions XP, 2003 and 7.

• The page_l1_map() function now works properly when using KVM and could lead to segmentation faults or other problems when calling page_l1_map(1 << 20) beyond the end of the l1_map array.

• Fixed I/O performance degradation.

• The "qemu-img info" command took a long time to respond when run immediately after creating an image with very small non-standard cluster sizes (for example, 512 bytes). This has been fixed

• Fixed a regression and live migration with the "--copy-storage-all" option now finishes successfully: no more "error: Unable to read from monitor: Connection reset by peer" messages.

• qemu now supports opening VMWare ESX image files.

• Added support for VMDK version 3 images: qemu-img can now convert them.
