[Qemu-devel] version command line option

[Qemu-devel] version command line option

[Pascal Erb]

hi,

actually I'm getting closer to qemu. And I like it ;-) . As I want to deliver 
some cd with a virtual machine on it, there's the need to check for an 
existing installation of qemu on the target host. I managed to check this by 
simply invoking qemu -h which returns 0 for success. But it seems to be 
impossible to do something like 

qemu --version

to find out some version information. Since this should be easy to implement, 
I'd do this. Any informations how to proceed?

Greetings,

Pascal

I came up with this but that looks overly complex and fragile :-)

qemu-x86_64 -h | head -1 | awk '{ print $3 }' | sed 's/,$//'

Hmmm. I agree with you. This looks really fragile since it is impossible to 
know in advance, head, awk or sed to be installed on the target host (having 
some ugly commercial OS with very low abilities in mind...). But thank you 
anyway that you strived for a quick solution :-)

My question tended more into the way: Where is the repository and where could 
I find the coding guidelines, etc? And how should I proceed to add the 
corresponding source code? About the repository I found already out how to 
make an anonymous checkout (git clone git://git.savannah.nongnu.org/qemu.git). 
Is there a howto document somewhere how to submit my code? Are there any 
public accessible documents about qemu's architecture or structure?
