--- Comment #1 from François Gouget <fgouget at codeweavers.com> ---
Currently we take the screenshots through Libvirt and thus QEmu + Spice.
However QEmu does not have access to the screen of VMs that use PCI-passthrough
graphics cards. So for these we may need to take the screenshots from inside
the guest.

Furthermore the screenshot is transferred uncompressed from the VM host to the
TestBot server which are not on the same LAN. That's pretty inefficient and may
limit how often we can take screenshots. There taking screenshots from within
the guest could be an advantage as it could deduplicate identical screenshots
before their transfer.

For instance the client tool could create a new png file every time the screen
changed, and then the TestBot could retrieve the list of files and retrieve
them with TestAgent.
