Hello!
Is there FLOSS alternative to emu8086 [1]? I wanted write similar to
that, based on qemu source code, for didactic purposes.
The problem is haven't found the documentation I need on
http://wiki.qemu.org . I would like to find a detailed explanation of
qemu architecture and source code,
Hi,
running 0.12.5 with a Ubuntu LTS 10.04.1 64-bit kernel I see the following
error after a few days with severe load (constant 100-200mbps input).
# uname -a
Linux ubuntu-newsfeed 2.6.32-24-server #43-Ubuntu SMP Thu Sep 16 16:05:42 UTC

this patch http://patchwork.ozlabs.org/patch/65137/raw/ solves problem
partially .. NICs are working with that but after a deeper look,
connection is lost when the netstack is flooded with higher traffic ..
i can connect with ssh|tel
