Updated qemu-kvm-rhev packages that fix a bug are now available.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linuxon AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-spacecomponent for running virtual machines using KVM, in environments managed by RedHat Enterprise Virtualization Manager.This update fixes the following bug:* When hot unplugging a virtual CPU (vCPU) from a guest using libvirt, thecurrent Red Hat Enterprise Linux QEMU implementation does not remove thecorresponding vCPU thread. Because of this, libvirt previously did not correctlyperceive the vCPU count after a vCPU had been hot unplugged. Consequently, anerror occured in libvirt, which prevented increasing the vCPU count after thehot unplug. In this update, information from QEMU is used to filter out inactivevCPU threads of disabled vCPUs, and the internal checks now pass and allow thehot plug. (BZ#1081462)Users of qemu-kvm-rhev are advised to upgrade to these updated packages, whichfix this bug.
