RHBA-2012:0012 - Bug Fix Advisory

Topic

Updated vdsm packages that fix various bugs are now available.

Description

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

These updated packages fix the following bugs:

• Previously, the vdsm-4.9 package ignored the "displayNetwork" parameter when

starting a virtual machine. This fix ensures that the "displayNetwork" parameter
is honored again and that VNC/SPICE traffic is directed over it, preventing
VNC/SPICE traffic from being directed over other networks.

Warning: Once a virtual machine is started on a host which honors the
"displayNetwork" parameter it will not be possible to migrate the virtual
machine to a host that does not. Additionally if or when the display network is
changed a VNC/SPICE connection that is already active beforehand will not change
network (BZ#757546).

• A race condition previously meant that issuing shutdown or destroy virtual

machine commands would sometimes result in an unexpected error from VDSM stating
that the virtual machine could not be found. VDSM has been updated to handle
these corner cases and not report this error condition unless it has actually
occurred (BZ#758716).

• Previously, logs collected by the vdsm-4.9-112 package from Red Hat Enterprise

Virtualization Hypervisor sometimes lacked a tree of the file system below the
/rhev/data-center/ directory, since the /usr/bin/tree command was missing. With
this update, a dependency for the tree command has been added to the VDSM spec
file, ensuring that it is installed. (BZ#766377)

• Previously, if the path given for an NFS storage domain contained spurious

slashes (/), VDSM failed to connect to that storage domain. This version
normalizes the storage path provided to VDSM, allowing connection of the storage
domain to proceed (BZ#767631).

All users who require VDSM are advised to upgrade to these updated packages,
which fix these bugs.
