RHEA-2017:0553 - Product Enhancement Advisory

Topic

New rhevm-guest-agent-docker packages are now available.

Description

The rhevm-guest-agent-docker package provides the guest agent for Red Hat Enterprise Linux Atomic Host virtual machines. The guest agent allows the Red Hat Virtualization Manager to receive internal guest events and retrieve information such as the IP address and list of installed applications from the guest. Additionally the guest agent allows the Manager to execute specific commands, such as shut down or reboot, on guest virtual machines.

Changes to the rhevm-guest-agent-docker component:

• Previously, when virtual machines were stopped during a system shutdown or reboot the shut down of those instances appeared to VDSM the same as if the virtual machine had been shut down gracefully from within the Guest Operating System. This incorrect information was sent to the Red Hat Virtualization Manager. This meant that the Red Hat Virtualization Manager did not start highly available virtual machines on a different host because it considered that the virtual machines had been shut down by the user from within the Guest Operating System. Now, VDSM detects when a virtual machine was shut down from within the system, with the help of the Red Hat Virtualization guest agent. VDSM can now differentiate between an unplanned shutdown and a user-initiated shutdown and reports this information to the Red Hat Virtualization Manager accordingly. This means that highly available virtual machines stopped during a system shutdown or reboot are now restarted on a different host. (BZ#1406033)
