RHBA-2016:1342 - Bug Fix Advisory

Topic

Updated vdsm packages that fix a critical bugs

Description

VDSM is a management module that serves as a Red Hat Enterprise Virtualization Manager agent on Red Hat Enterprise Virtualization Hypervisor or Red Hat Enterprise Linux hosts.

Changes to the vdsm component:

• Previously, when the VDSM service was restarted on a host, the host would still respond to queries from the Manager over JSON-RPC protocol, which could lead to incorrectly reported status of virtual machines in the engine database. In the case of highly available virtual machines, this would cause the virtual machine to be restarted under certain circumstances even though the virtual machine was running. This issue has now been resolved, and API calls are correctly blocked while the VDSM service is starting. (BZ#1344075)
