KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev packages provide the user-space component for running virtual machines using KVM in environments managed by Red Hat Virtualization Manager.

Bug Fix(es):
When attempting to use a virtual CPU with the “invtsc” feature, the “nonstop_tsc” flag was not set for the guest. This update adjusts the flag to be migrateable, and “nonstop_tsc” is now properly set when requested. (BZ#1413897)
Previously, the QEMU emulator failed to open disk images with backing files stored on a Gluster volume. This update ensures that QEMU is able to handle Gluster disk URIs correctly, and the problem no longer occurs. (BZ#1425125)
Prior to this update, creating a new GlusterFS instance in some cases consumed an excessive amount of memory. This update reuses data for existing GlusterFS volumes, which reduces the memory consumption when creating new instances. (BZ#1413044)
Under certain circumstances, guest machines previously encountered I/O errors or were paused when a large number of block transfer actions was being performed. With this update, QEMU ensures that the number of block transfers does not exceed the host limit, which prevents the described problem. (BZ#1431149)
