[virt-tools-list] [PATCH virt-viewer 0/4] RFC: Avoid opening extra displays in fullscreen mode

[Jonathon Jongsma]

This is a second attempt to fix an issue where extra displays are sometimes
opened when starting virt-viewer in --full-screen mode. This can happen when
the guest has more displays enabled than the client requests. My first attempt
involved changes in spice-server to prevent sending out "old" monitor 
configurations at startup if the client had already sent a new config. In
contrast, this patch attempts to deal with the issue from the client side. It
does this by sending out the monitor configuration and then waiting for a
certain amount of time to let the server reconfigure itself before creating any
display windows, etc. If the guest does not configure itself in time, it just
gives up and creates displays to match the current state of the guest.

The timeout is rather arbitrary. In this patch it's set to 2 seconds, but I
suspect that's far too low to be generally useful. I've so far only tested it
with a host and client on different machines on a local network. I think the
timeout will probably need to be increased to deal with slower and higher
latency networks.

Jonathon Jongsma (4):
  SessionSpice: keep a list of display channels
  SessionSpice: save initial fullscreen configuration
  SessionSpice: Keep track of auto conf state
  Fullscreen auto-conf: wait for server to be configured
