[Qemu-devel] Nothing happens

[Qemu-devel] Nothing happens

[Rudi Lippert]

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!

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,
Hetz

[Rudi Lippert]

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,
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

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

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...

Do you have the SDL devel packages installed? Usually people have this 
problem when they compiled Qemu without SDL... Could you compare what 
SDL packages are installed on the two computers?

I had similar problems when I run qemu on NT4 for a while ago. Using "-nics
0" make the system start. The sad thing is that qemu by default (at least
never versions) doesn't write any error messages or output when it's started
on Windows. I did report this for a while ago by didn't have any response.

PEK,

The no-console-on-Windows can be resolved by linking extra libraries, as
per http://lists.gnu.org/archive/html/qemu-devel/2005-04/msg00422.html

Actually, no additional libs are needed, just the -mconsole compile-time
option. Another option is to edit the compiled executable, I posted a small
program that does that a while ago:
