I add an id to the virtio-serial-pci device, it can fix "Bus 'virtio-serial0.0'
not found"

Seems like nothing is writing to the port on the other side. Are you
sure you are using a version of spice-server that supports the
streaming agent? Lastest git master would probably be the best.

Re: [Spice-devel] not clear how to use streaming agent
Hello, Thanks for your response, you are right,I am using Intel vGPU and running a Windows7 guest. So I am not clear how to using streaming-agent in Window 7 guest. Next I will try linux as the guest. Intel provides a dma-buf of the host at 30ms intervals(the dma-buf is full-screen size), spice-server's commands tree is used for video stream detection. My idea is capture guest video stream(use plugin) and send to client direct, do not use spice-server's commands tree for video stream detection.At present, it is in the pre-research stage.

Hello, So, you are using Intel vGPU and running a Windows 7 guest. Theoretically, spice-streaming-agent can do what you want, run on the guest to capture the video and send it via SPICE to the client. But, currently spice-streaming-agent is written for Linux guests. So first you'd need to make it work on Windows (for example the virtio-serial port name is different on Windows guests, cursor handling is different (can be disabled at first)). Also you need a spice-streaming-agent-plugin. The mjpeg plugin is one example (it too is written for Linux). Look at Snir's experimental gst-plugin [1] as another example. Possibly there exists a gstreamer src to capture windows screen and x264 would work on Windows too. You may want to use hardware encoding if possible. If Intel provides a dma-buf of the host, it may be even better to do it from the spice-server somehow, similar to what's done with virgl (requires code-modifications). When you have these written, you'd need We'll be happy to know if you make progress or if you need more help (and of course if you send patches :-) Uri.___ Spice-devel mailing list Spice-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/spice-devel

Thank you for the compliment. "[1] https://www.linux-kvm.org/page/SPICE; is what I want. At first, I running Windows 7 as the guest, not clear how to use streaming agent.

That you want to capture the video and send it to the client is too vague and low-level. What do you want to use it for, the high-level use case? SPICE alone without the streaming agent can do what you are describing, you should probably start with that: Install SPICE from your distribution packages, follow a guide like [1], there are some more information in [2]. If you know you need more than regular SPICE can offer, please describe it.

I hope you will pardon me for this.

Sure, first off, what exactly do you want to achieve? If you just want to remotely access your VM (see the graphical desktop and interact with it), you don't need the streaming agent for that, SPICE can do that for a long time without it. Streaming agent is designed for a very specific case of capturing and encoding the desktop from within the guest, which only has an advantage to the regular old SPICE approach if you have a physical GPU or a vGPU assigned to the guest to accelerate the process. If you still think streaming agent is what you need, please describe in detail what is your use case. > 1.host environment and Software version: > centOS(Mini install) > GVT-g kernel: https://github.com/intel/gvt-linux/ (branch: topic/dmabuf) > QEMU: https://github.com/intel/igvtg-qemu (branch: qa/dma_buf) > streming agent:https://gitlab.com/spice/spice-streaming-agent > spice-server version:0.13.3 > spice-protocol version:0.12.12 > > > 2.build info > kernel: > make -j 8 > make modules_install && make install > reboot > > > qemu: > ./configure --prefix=/usr --enable-kvm --disable-xen --enable-debug-info > --enable-debug --enable-sdl --enable-vhost-net --enable-spice > --disable-debug-tcg --enable-numa --enable-libusb --enable-curl > --enable-usb-redir --enable-linux-aio --target-list=x86_64-softmmu > --enable-gtk --with-gtkabi=3.0 > make -j 8 > cd roms/seabios > make -j 8 > cd - > make install > cp roms/seabios/out/bios.bin /usr/bin/bios.bin > > > spice-protocol: > ./configure --prefix=/usr > make -j 8 > make install > > > spice-service: > ./configure --prefix=/usr --enable-manual=no --disable-silent-rules > --disable-smartcard --disable-celt051 --enable-client CFLAGS="-g -O0" > CXXFLAGS="-g -O0" > make -j 8 > make install > > > streming agent > ./autogen.sh > make -j 8 > make install > > > 3.run qemu > /usr/bin/qemu-system-x86_64 \ > -m 8192 \ > -smp 4,sockets=1,cores=4,threads=1 \ > -M pc \ > -name win71 \ > -hda /Image/vm/win7_base.img \ > -bios /usr/bin/bios.bin -enable-kvm \ > -k en-us \ > -vga none \ > -display egl-headless \ > -spice disable-ticketing,port=6901,streaming-video=off \ > -machine kernel_irqchip=on,usb=on \ > -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 \ > -cpu host -device usb-tablet \ > -device > vfio-pci,sysfsdev=/sys/bus/pci/devices/:00:02.0/5b8d581a-2dc9-11e8-8238-000906258002,x-display=on,x-igd-opregion=on > -device > virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel1,id=channel1,name=org.spice-space.stream.0 > -chardev spiceport,name=org.spice-space.stream.0,id=charchannel1 Are you running Windows 7 as the guest?
