QEMU does not support the LAN7800 device (ven424-7800). For network access it uses a USB CDC Ethernet device (int2-6-0), which is not supported by USPi, but by Circle (lib/usb/usbcdcethernet.cpp). If...

I'm familiar with Circle (but not with Ableton Link) and I would help. But I'm afraid Ableton Link requires the ability to receive multicast network frames? This is currently not...

Circle has its own TPC/IP stack, which cannot easily replaced with an other stack. This is also not the main problem. The (five different) low-level NIC drivers in Circle do...

IP multicast send and receive support is now on the *develop* branch. There is a test program in *test/mdns-receiver*, which demonstrates the receiver. After calling `Connect()` for a socket, one...

You should have told, that you are working on this. ;) My code is slightly tested and comes with multicast support for all supported NICs, but without IGMP. GPT told...

I had a look at your code and it's astonishing, what these tools can do today. But I never used them to code for Circle so far. I would also...

The IGMP support in Circle is making progress. I'm testing this with Wireshark at the moment. Circle is responding to Membership Queries, sends a Query by itself on joining a...

The IGMPv2 support is on the *develop* branch. Unfortunately I wasn't able to setup a test network, where the IGMP function was really verified. It was only tested using Wireshark....

I had a closer look now onto the Ableton Link source. I think somebody would have to port the Asio library to Circle first, which seems to be a huge...

I can reproduce this with an older QEMU version. I think your command line is OK. I'm afraid there is no quick solution for this. I tried sample/26- cpustress again...
