RHBA-2016:2673 - Bug Fix Advisory

Topic

Updated qemu-kvm-rhev packages that fix several bugs and add various enhancements are now available for Red Hat Virtualization Hypervisor 7.

Description

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

The qemu-kvm-rhev packages have been upgraded to upstream version 2.6.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#1289417)

In addition, this update adds the following enhancements:

• Support for the XSAVES, XSAVEC, and XRSTORS instructions in Intel Xeon v5 guests has been added to the KVM hypervisor and kernel code, and to the libvirt API. (BZ#1327589)
• This update adds support for removing virtual CPUs (vCPUs) from running KVM guest virtual machines on AMD64 and Intel 64 hosts, also referred to as the vCPU hot unplug. In combination with the vCPU hot plug, this enables users to dynamically allocate resources to guests without the need to shut them down. (BZ#1087672)
• It is now possible to hot plug vCPUs to guest virtual machines running on IBM System z hosts. (BZ#1172917)
• This update enables the post-copy guest migration feature for KVM guests. When used, post-copy migration immediately pauses guest vCPUs on the source host, transfers only a minimum of memory pages, and activates the guest vCPUs on the destination host. This significantly reduces the downtime of the migrated virtual machine, but the migration cannot be reverted while it is in progress. In addition, post-copy migration is guaranteed to finish regardless of how rapidly the memory pages of the source guest change, so it is optimal for migrating guests in heavy continuous use. (BZ#830966)
• With this update, Non-Volatile Dual In-line Memory Module (NVDIMM) persistent memory is supported and can be assigned to guest virtual machines. (BZ#1270345)
• This update adds libvirt support for Intel e1000e network interface controller for PCI-Express. This enables more effective use of virtual networks on recent Intel machine models and operating systems. (BZ#1343092)
• With this update, it is possible to use TLS encryption with the Transmission Control Protocol (TCP) back end for character devices. As a result, using the TCP back end is more secure and efficient. (BZ#1300773)

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