RHBA-2013:1073 - Bug Fix Advisory

Topic

Updated vdsm packages that fix various bugs are now available.

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.

This update fixes various bugs.

Changes to the vdsm component:

• SSL handshakes are now cached with the hosts in order to reduce CPU load on

the hosts. (BZ#857035)

• Previously, it was not possible to attach a fibre channel storage domain to

Red Hat Enterprise Virtualization when using a QLogic iSCSI HBA offload card.

Now, it is possible to attach a fibre channel storage domain to Red Hat
Enterprise Virtualization when using a QLogic iSCSI HBA offload card.
(BZ#972863)

• Previously, an unhandled EPERM exception while attempting to unregister a FD

lead to the virtual machine Channel Listener thread dying.

Now, an unhandled EPERM exception while attempting to unregister a FD no longer
leads to the virtual machine Channel Listener thread dying. (BZ#972749)

• Previously VDSM provided unnecessary warning messages regarding storage

latency. This led users to believe that the storage domains were operating too
slowly, even when they were fine.

Now, VDSM accurately provides warning messages so that only actual cases of
problematic latency are reported. (BZ#972700)

• Previously accessing the TUI via SSH would sometimes produce out of place

debug messages in the background of the TUI screen. This has been corrected so
that the TUI appearance is as expected. (BZ#965762)

All users managing Red Hat Enterprise Linux Virtualization hosts using Red
Hat Enterprise Virtualization Manager are advised to install these updated
packages, which fix these issues.

These updated packages will be provided to users of Red Hat Enterprise
Virtualization Hypervisor in the next rhev-hypervisor6 errata package.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
