The user is using virt-viewer with Spice as the client and a Windows 7 guest VM. + +The issue seems to be that when the guest VM sends many bulk USB transactions (like 50 per second), each one takes around 10-20 milliseconds, leading to delays of up to 1000 milliseconds for all 50. This causes timeouts in the VM because the responses aren't coming back quickly enough. + +The log provided shows that QEMU is handling these bulk packets sequentially—each one after another on a single thread. The user suggests sending them concurrently using multiple threads, which would speed up the process since they wouldn't be waiting for each packet to complete before sending the next. + +Looking at the categories: it's related to USB redirection performance. The problem isn't in the translation from source architecture or assembly; it's more about how QEMU handles the I/O requests. It’s specifically about USB device handling and performance issues with bulk transfers, which falls under the 'usbredir' category. Since the delay is affecting real-time data transfer speeds, it relates to device performance. + +Considering all the categories given, the most fitting one here is 'device', as it's directly dealing with USB device communication and its efficiency in QEMU. +</think> + +device \ No newline at end of file |
