qemu-kvm-1.5.3-141.el7.5

Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM.

This update fixes the following bug:

* Previously, the memory mapping of processor access to base address registers (BARs) smaller than the system page size was incorrect. As a consequence, devices assigned to a guest virtual machine using the vfio-pci driver did not work, which in some cases prevented the guest from booting. This update fixes the QEMU emulator to map the affected devices properly, and the described problem no longer occurs. (BZ#1515110)

Users of qemu-kvm are advised to upgrade to these updated packages, which fix this bug. After installing this update, shut down all running virtual
machines. Once all virtual machines have shut down, start them again for this update to take effect.
