Here's the stack trace for where it falls out... (it remembered my last setting of 1024x768 on the 5th QLX device and now doesn't start)... #0  0x00007fd349999ed5 in raise () from /lib/libc.so.6 #1  0x00007fd34999b3f3 in abort () from /lib/libc.so.6 #2  0x00007fd34d5bba92 in fill_bits (display_channel=0x1f30020, in_bitmap=<value optimized out>, drawable=0x44fe9c90) at red_client_shared_cache.h:51 #3  0x00007fd34d5bc423 in red_send_qxl_drawable (worker=<value optimized out>, display_channel=0x1f30020, item=0x44fe9c90) at red_worker.c:5677 #4  0x00007fd34d5bd1dd in display_channel_push (worker=0x44fad500) at red_worker.c:6182 #5  0x00007fd34d5c40cc in red_worker_main (arg=<value optimized out>) at red_worker.c:6751 #6  0x00007fd34a5c2fc7 in start_thread () from /lib/libpthread.so.0 #7  0x00007fd349a3759d in clone () from /lib/libc.so.6 #8  0x0000000000000000 in ??

Some time ago, Izik said the following: >Spice currently support only 4 monitors, however it is just a matter of changing a #define to make it run with more >monitors. >What worry me with 8 monitors is the amount of pci memory that we will have to allocate I am not sure if there >will be enougth memory below the 4giga address I have assembled a 6 head thin station (if you can call it really thin ;)) and wanted to try SPICE with 6 heads. So I went ahead and modified vdesktop/qemu/hw/pc.h:#define QXL_MAX_MONITORS 4 to 6 compiled everything, and started with the "-qxl 6". Windows was able to detect two additional monitors, i proceeded with the driver install. I then went into Properties and did "Extend my windows desktop..." on the 5th monitor. qemu crashed. I then restarted, now the 5th monitor was enabled. I tried setting resolution to > 834x762 and apply, another crash... (640x480 works)... Tried enabling 6th monitor - crash! Tried adding "-qxl 6,ram=32" no change... I've also changed #define DEFAULT_QXL_RAM_MB_SIZE 64 to 128 and Windows clients stopped booting. I tried "-qxl 6,ram=128" but that also has started hanging up the windows vm boot... really shooting in the dark here, but hey that's just a try ;) I'm using stable 0.4 release, since in the unstable the preformance of my virtual machines is very poor. not sure why. I'd be glad to keep testing 6 monitor setup ;) Thanks!!!
