And we don't check all the lib versions for qemu runtime, that'd be a waste of time, so this is quite alright, I think. I updated everything spice-related and I still can't properly build qemu particularly because of the patch you mentioned. And I update everything from git. Then I looked there and I see no such function, no wonder the build fails with undefined reference to spice_qxl_set_monitors_config_limit. Although that would mean that itqemu tries to call spice_qxl_set_monitors_config_limit but the entry point ended up being called spice_qxl_set_max_monitors in spice-server :-/
I spend all morning fixing this to be installed properly in the system. Anyway, I finally managed to make this work and found out the guest I used for it is not ready to have multiple monitors. Anyway, looking at everything else this definitely works, so ACK, I'll push it in a while. In the meantime, is the only thing this does limiting the maximum? Is it there just to save some memory or why? Because otherwise I can't see the use-case in that. I'm not saying there isn't one, just that I can't find it. And I even looked under the fridge :) Have a nice day, Martin
