RHEA-2016:1700 - Product Enhancement Advisory

Topic

Updated rhev-guest-tools-iso packages that fix several bugs and add various enhancements are now available.

Description

The rhev-guest-tools-iso package contains tools and drivers. These tools and drivers are required by supported Windows guest operating systems when installed as guests on Red Hat Virtualization.

Changes to the ovirt-guest-agent component:

• Setting the USEPLATFORMCLOCK option in bcdedit to "yes" leads to degraded performance on the guest side when the Hyper-V extensions are enabled, which is the default for Red Hat Virtualization for the affected systems (Windows 2008 R2 Server and newer, Windows 7 and newer). The guest agent now removes this option on every start of the guest agent service unless this functionality is disabled in the configuration of the guest agent. When the option apply_timer_configuration in the general section is set to false, the agent will skip this behavior and leave the bcdedit configuration completely untouched. (BZ#1335309)
