RHBA-2020:0457 - Bug Fix Advisory

Topic

An update for qemu-kvm-rhev is now available for Red Hat Virtualization Host 7.

Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.

Bug fixes:

• CPUID_7_0_EDX_ARCH_CAPABILITIES is not enabled in VM qemu-kvm-rhev (BZ#1730603)
• MDS_NO exposure to guest - qemu-kvm-rhev (BZ#1743633)
• Live storage migration fails with: TimeoutError: Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchConnectGetAllDomainStats) and the VM becomes 'Not Responding' (BZ#1755340)
• After host update, older windows clients have large time drift (BZ#1767624)
• qemu-kvm crashes when Windows VM is migrated with multiqueue (BZ#1779100)

Users of qemu-kvm are advised to upgrade to these updated packages. 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.
