I'm at a bit of a loss to explain this. My strace output is quite
different. I'm running the 2005-05-18 snapshot of qemu 0.7.0.
I think it's time to start inserting fprintf(stderr, "OK1\n");
statements into your code, recompiling, to trace the error origin (or
use gdb).
In detail...

well, nothing really means nothing. the guest window does not come up, and
the console window does not show anything, even with -monitor stdio. the
thread just goes to sleep.
strace may be interesting, and 5kb are not too much, i think, so here it
comes.
thanks for now,
Rudi

How do you mean 'nothing'? Can you be more precise?
Does it display the network interface configuration? open the guest
window? Or really is does it just hang immediately? With the '-monitor
stdio' option does it give you a monitor prompt?
Have you tried running qemu with:
strace qemu <your normal options> 2>/tmp/qemu.log

My OS:
GNU/Linux (Gentoo)
QEMU Version:
0.7.0, compiled using the standard ebuild; no kqemu or qvm86
I'd include the exact build options, but they're rather lengthy.
I've experienced the same problem with 0.6.1 and CVS somewhere in between
0.6.1 and 0.7.0.
Cheers,

How about starting with trivial details such as:
* Which host OS do you use?
* Which QEMU version?
* binaries downloaded or did you compile it?
Thanks,

Hi!
I keep wondering why QEMU does not do anything when I start it.
First of all: yes, I know how to use QEMU. When I use it on my other
PC, it works like a charm.
The major difference between the two systems is, that this one is an
AMD64. And here is what happens when I start QEMU:
Nothing. No output, no CPU activity.
I know that this is not a whole lot of information, but I will provide
any further information that is requested.
Thanks in advance!
