Michal has provided a patch which looks ok to me (I've already acked it), so I'll reassign the bz to him. Reproduced on qemu-kvm-0.12.1.2-2.189.el6.
Boot a guest with "-qmp tcp:0:4444,server,nowait" and connect with "telnet $host_ip 4444"
{"execute":"query-commands"} there's no "screendump" commands.
Verified on qemu-kvm-0.12.1.2-2.195.el6.
1. Boot a guest with qmp:
/usr/libexec/qemu-kvm -m 2G -smp 2 -cpu cpu64-rhel6,+x2apic -drive file=/mnt/win7-64.raw,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none,format=raw -device ide-drive,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup -device rtl8139,netdev=hostnet0,mac=00:10:1a:3b:20:1f,bus=pci.0,addr=0x4 -boot c -uuid 6d59434d-3f1c-4558-afc3-37e2cc430d6b -rtc-td-hack -no-kvm-pit-reinjection -monitor stdio -name win7-64 -spice port=5930,disable-ticketing -vga qxl -usb -k en-us -global qxl-vga.vram_size=33554432 -device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x5 -device qxl,id=video2,vram_size=67108864,bus=pci.0,addr=0x6 -device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x7 -chardev socket,id=channel0,host=127.0.0.1,port=12345,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=channel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -qmp tcp:0:4444,server,nowait
2. $ telnet 10.66.10.54 4444
{"execute":"qmp_capabilities"}
{"return": {}}
{"execute":"query-commands"}
{"return": [{"name": "block_stream"}, {"name": "block_job_cancel"}, {"name": "block_job_set_speed"}, {"name": "quit"}, {"name": "eject"}, {"name": "__com.redhat_drive_del"}, {"name": "change"}, {"name": "screendump"}, {"name": "__com.redhat_qxl_screendump"}, .......
There's "screendump" commands already.
3. {"execute":"screendump","arguments":{"filename":"/home/picture-1.pnm"}}
{"return": {}}
{"execute":"screendump","arguments":{"filename":"/home/picture-2.pnm"}}
{"return": {}}
The screendump command works well, guest desktop screen can be saved successfully.
So, this bug is fixed.
