Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated qemu-kvm-rhev packages that fix two bugs are now available for Red Hat Enterprise Virtualization Hypervisor 7.
Description
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 Enterprise Virtualization Manager.
This update fixes the following bugs:
- When a guest virtual machine was configured as a vhost-user server and the back end was restarted, the guest was not able to recover. With this update, the back end is able to discard the SET_VRING_BASE value and resume from index. This allows the guest to recover successfully in the described scenario. (BZ#1348593, BZ#1356892)
- Previously, deleting a guest virtual machine set up as a vhost-user server caused the socket file on the host machine to be preserved. This update adjusts the guest clean-up mechanism to ensure that in the described situation, the socket file is deleted as expected. (BZ#1351892)
Users of qemu-kvm-rhev are advised to upgrade to these updated packages, which fix these bugs. 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.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
