Maybe I solove the problem.

I use the qemu-img make a new GustOS img. And install the debian5 on
the image file with option -net nic, model=virtio.
./x86_64-softmmu/qemu-system-x86_64 -hda debian.img -cdrom debian.iso
-net nic, model=virtio

This email reads as:

  -net nic, model=virtio

If this is in fact what you're running with, the whitespace is broken; 
correct would be to have no space after the comma, as so:

  -net nic,model=virtio

[Qemu-devel] Re: Network connections stalling (due to lost interrupts/ticks?)

2007-08-03 Thread Charles Duffy
Well, behavior with the patch applied is certainly different.

The large download I'm running still times out; however, it is now able
to resume without needing to bring the interface down and back up.
However, after the first timeout, subsequent timeouts occur with much
greater frequency -- still making this multi-GB download an
impracticality when using -net tap.

The flood ping is not killing the network connection, though it is
interrupted by frequent messages: Warning: time of day goes back
(-23150us), taking countermeasures. (This is no the high end of the
time variances shown; the smallest are on the scale of 120us

[Qemu-devel] etherboot support in x86_64 mode?

2007-08-02 Thread Charles Duffy
I notice that the -boot n etherboot support doesn't appear to work 
when emulating x86_64 hardware (invocation as qemu-system-x86_64). Is 
this intentional? A known issue?
