Details

Updated qemu-kvm packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux
on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running
virtual machines using KVM.

This update fixes the following bugs:

* Recent changes to the block layer resulted in a disk I/O performance
degradation due to the way block length is calculated and cached internally.
This update improves the logic for calculating such lengths and restores
performance to the expected levels. (BZ#1025596)

* Due to a regression, the "qemu-img info" command took too much time to respond
with the "cluster_size=512,preallocation=metadata" option. This bug has been
fixed and "qemu-img info" now responds within one second. (BZ#1029327)

* On images created with very small non-standard cluster sizes (for example, 512
bytes), the "qemu-img info" command could take a long time to respond if run
immediately after an image creation. This bug has been fixed, and "qemu-img
info" now works as expected. (BZ#1029327)

* When doing live migration with the "--copy-storage-all" option, the virsh user
interface failed with the following error message:

"error: Unable to read from monitor: Connection reset by peer"

This bug, caused by a regression, has been fixed, and live migration now
finishes successfully. (BZ#1029329)

* Previously, qemu (for example, the "qemu-img info" command) could not open
VMWare ESX image files. A patch fixing this bug has been provided, and ESX
images are now handled correctly. (BZ#1028252)

Users of qemu-kvm are advised to upgrade to these updated packages, which fix
these bugs.
