This is really more suitable for qemu-devel. In general, qemu doesn't trap the real hardware interrupt; it waits for a signal (or select()) indicating that there are packets waiting to be received. Depending on how the emulated nic is configured, there may or may not be a virtual interrupt generated. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
