Doc Text:
Previously, using the virt-viewer utility to view a guest virtual machine in virtual network computing (VNC) graphic mode did not properly generate the graphical output if virt-viewer was disconnected and then reconnected in a short span of time. With this update, a server refresh is reliably triggered on reconnecting with virt-viewer in the described scenario, and it shows the expected graphical output.
