RHEA-2014:0063 - Product Enhancement Advisory

Topic

Updated spice-vdagent-win packages that fix several bugs and add various
enhancements are now available.

Description

spice-vdagent-win provides a service and an agent that can be installed and run
on Windows guests. The SPICE vdagent supports multiple monitors and is
responsible for client-mouse-mode support.

This update fixes the following bugs:

• Due to issues with converting to UTF-8, EOL was stripped out when pasting text

to a Windows 7 guest, and the text was pasted without new lines. This has been
fixed so EOL is no longer stripped out when copying from client to guest.
(BZ#872252)

• Previously copying and pasting a large amount of data to a clipboard caused

the connection to timeout and the clipboard to be inaccessible, but vdagent
continued attempting to paste the data to the clipboard. Now under these
conditions the connection hits a timeout, but vdagent stops trying to write data
to the clipboard. (BZ#951618)

• When using sparse multi monitor, enabling display n in addition to display 1

enables all displays (1, ..., n). This has now been fixed so that only the
relevant monitors are enabled, preventing inconsistent behaviour. (BZ#953973)

• There are were cases where the _displays vector was being iterated, and some

of the vector entries were NULL. This caused the agent to be aborted and
restarted by the service several times. This has been fixed, now the agent
enables virtual machines with multiple monitors to show all monitors correctly.
(BZ#958051)

This update also adds the following enhancements:

• A virtual machine running the Windows agent now sends the

VD_AGENT_CLIENT_DISCONNECTED message when a client has disconnected, to prevent
VDAgentMessage fragments from being wrongly delivered to the agent. The
VD_AGENT_CLIENT_DISCONNECTED message also enables the agent to reset its
VDP_CLIENT_PORT state. (BZ#BZ#956133)

• Support has been added for agent-based client to guest file transfers. Users

can now drag and drop files from a client to a guest. (BZ#956146).

All Red Hat Enterprise Virtualization users are advised to upgrade to these
packages which address these issues.
