RHEA-2018:2625 - Product Enhancement Advisory

Topic

Updated cockpit packages that fix several bugs and add various enhancements are now available for Red Hat Virtualization.

Description

Cockpit is a Linux system administration tool with a web UI, easy setup, and minimal system footprint at runtime. When installed on hosts in Red Hat Virtualization, it provides monitoring and management functions beyond those available in the Administration Portal. Cockpit is installed by default on Red Hat Virtualization Host (RHVH).

Changes to the cockpit component:

• This release updates the cockpit package to version 172, including the following enhancements:
• Use authenticated libvirt connection by default
• Add virtual CPU configuration (BZ#1607446)
• Previously, it was not possible to send an non-maskable interrupt (NMI) to a non-responsive guest operating system.

In this release, users can send an NMI via the Cockpit. A new menu option called "Send Non-Maskable Interrupt" was added to the "Shut Down" menu that is available from the Virtual Machines tab. It sends a 'virsh inject-nmi' command to the required virtual machine, and it is sent regardless of the virtual machine's state and without checking the type of operating system or its settings.

In the event of an operation system that is not installed or configured correctly, no action will be taken. (BZ#1297037)
