So far we have a test setup with a kgdb to debug the guest and a regular = gdb to debug QEMU. We are still trying to reproduce the bug in a test environment. Once the bug reproduced would you have hints on what to look for in virti= o-net driver state ? Any idea to debug this would be wellcome. Best regards Beno=EEt
