I applied your patch to 10.99.6 and built a XEN3_DOM0 kernel (XEN3_DOM0 + bigger IFQ_MAXLEN). The result was, while the kernel booted up, when a 32 bit 9.x PVH+PVSHIM guest performed its ifconfig against a xennet interface, the DOM0 rebooted. No DDB, no obvious panic message,... just a hang for a bit and a reboot. I also observed the DOM0 appear to hang up hard before the guest started while poking at other stuff. I don't know if the patch caused the trouble, or if 10.99.6 has trouble for me in a general sense (or if I am not allowed any more to make IFQ_MAXLEN larger than the default). I won't have time to mess with this again for a while, but the results were not encouraging. -- Brad Spencer - b...@anduin.eldar.org - KC8VKS - http://anduin.eldar.org
