RHBA-2013:1819 - Bug Fix Advisory

Topic

Updated spice-server packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The Simple Protocol for Independent Computing Environments (SPICE) is a remote
display protocol for virtual environments. SPICE users can access a virtualized
desktop or server from the local system or any system with network access to the
server. SPICE is used in Red Hat Enterprise Linux for viewing virtualized guests
running on the Kernel-based Virtual Machine (KVM) hypervisor or on Red Hat
Enterprise Virtualization Hypervisors.

• Previously, the SPICE server assumed that the client was connected until they

got disconnected. When the SPICE client became unresponsive, the server
continued trying to communicate with it. Consequently, queues (such as driver
commands ring) filled up, and the guest display driver continued waiting. With
this update, the SPICE server monitors if the client is responsive, and
disconnects if it is not. (BZ#1027244)

Users of spice-server are advised to upgrade to these updated packages, which
fix this bug.
