I wrote a websocket client to help reproduce the bug without a browser: https://github.com/anisse/websocktty
You can install it to your $GOPATH/bin (defaults to ~/go/bin) with "go get github.com/anisse/websocktty" I can reproduce the bug with it by simply pasting a long-enough (5 to 20 characters) string. I could not reproduce the bug with qemu's "-serial tcp" and netcat, so this problem might indeed be limited to the websock channel implementation. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1828608 Title: Chardev websocket might not support pasting more than a few chars Status in QEMU: New Bug description: When sending more than 4-5 characters on the websocket serial console (with pasting for example), the guest might not receive all of them, or worse interpret the input as Magic SysRq keys. This might be due to the io loop not checking the backend readiness before calling the read function. Attached patched fixes the problem on my system. I'm not sure it's the proper approach, this is just to start discussion. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1828608/+subscriptions
