[Qemu-devel] qemu and configuration file?

[Giuseppe Della Bianca]

Hi.

The options of qemu are so many, that would be the case to use configuration 
file.  

You are interested to this? 
If the answer is, I could also think to insert in qemu the code of management 
of the configuration file of my program gesconf  
( http://savannah.nongnu.org/projects/gesconf ). 

Regards.

Re: [Qemu-devel] qemu and configuration file?

[Giuseppe Della Bianca]

Hi.

My idea is this:  
- qemu start 
- set up of the hardcode parameters 
- reading of the configuration file and set up of the parameters 
- set up of the parameters of command line 

Example of configuration file:
[general]
  ....
  [vlan0]
    ip= x.y.x.w
    mac= l:m:n:o
    ....
  [/vlan0]
[/general]

[suse.img]
  ....
  [vlan3]
    mac= h:j:k:l
    ....
  [/vlan3]
[/suse.img]

[win.img]
  ....
  [vlan2]
    mac= z:x:c:v
    ....
  [/vlan2]
[/win.img]

Result: 
- full compatibility with every version of qemu 
- more flexibility 
- possibility to set up the hardcode parameters 
- possibility of parameters personalized for every image 

One similar thing, with smaller flexibility, is possible 
 without modify qemu and using one series of bash script.

Comments are welcomes (at least one "it does not interest to us"). 

Regards.

I'd go for the shell script. If enough people like it I'm sure it could be 
included with qemu.
Config file support without a decent GUI seem rather pointless.
The big advantage of doing it as a shell script is it's dead easy to hack to 
include whatever custom magical features people want.

It would be useful for automatic startup of the VMs by init scripts.
OTOH it's very simple to create a config file parser with
perl/python/bash who can wrap around qemu options.

If I find 1 free hour tomorrow I'll post a POC.

It is simpler to write the bash script right away, especially if you know 
init scripts.

I wrote one a long time ago called vqemu. It's a simple bash script that
gives support for a really primitive style of config file (basically a file
full of "qemu parameter"="on/off" or "parameter"="value". All I have to do is
type 'vqemu' in the right directory (or call 'vqemu -config file') and I get
a VM running with no troubles.

If people think this is a good idea I can easily update this to qemu 0.8.0's
options.

I understand and I agree yours (and of the others that prefer the scripts) 
motivations.  

To modify qemu allows to make things that with script are impossible, and one 
 linear configuration file is the first step for having one graphical tools 
easy and friendly (I think as an example at kde, samba and others).

  If we'd go for a config file at all with such a complicated structure, i see no reasons why to 
choose anything else than xml for it. We have tons of xml libs that can be used for gui's (think 
perl, tk, python etc...). Certainly better every dude writing it's own XuPeRpArSeR that will be 
broken and compatible after a major change in qemu ...
  Another choice would be the pure rc (just 'item = value' lines) without any supersmart blocks.

xml style or rc style, please no hack in betweeen :)

I like VMWare style. Maybe it should be possible to share the same
config file between qemu and VMWare, also to favour user migration.

I'd like to see some more things in it (besides that windows clients  
can't handle (ba)sh scripts:

- State of the machine (saved/running/snapshot)
- what cpu/machine
- further information (Author, Copyright...)
- paths that can be handled by every plattform
...

so you can g(zip) up a vm and send it to your fellow tester and he  
can run it on every plattform...

and of corse advanced configuration/packages are only good for a GUI!

else you can really stay with bat/sh ;)

Re: [Qemu-devel] qemu and configuration file?

[Mike Kronenberg]

I made a proposal some month ago based on xml:
http://lists.gnu.org/archive/html/qemu-devel/2005-08/msg00034.html

I use this style of xml property lists for the configuration of the  
vm of Q (slightly alter by now).
Q is a OS X port of QEMU http://www.kberg.ch/q

I ran recently into some troubles with arguments that can appear  
multiple times, like -net and -redir.
I'm now about to changes my configuration files. Having a well  
defined style of configuration files would help making simple guest  
packages, that could be used on multiple systems...

The xml configuration file are too much hard to consult and to modify 
directly from a human. 
The idea to use additional library and therefore to add obligatory 
prerequirement to qemu, is not an idea that have appeals for me.

My program and library can manage from the basic ' key value' 
to the configuration file of xfree/xorg (and multiple keys, groups with name 
in one key) without particular problems.

As an example: 
Qemu set up a function of callback, calls one function of my library for 
 demands one group (or some groups) and one key (or some keys), my library, 
using the callback function it gives back the value (or some values). 
Then qemu it will make what he must make, and I do not see particular problems 
of incompatible with a major change in qemu.

> xml style or rc style, please no hack in betweeen :)

All depends from functions that are wanted to be added at qemu, without the 
group not it goes beyond simpler configurations.

It's not hard to edit XML (when it's nicely structured, and not clumped all
in a single line), but from my experience it just doesn't give enough
advantage over flat files for storing simple configuration, to justify
writing the much more complex parsing code it needs.

As I mentioned in a earlier thread about config files, one of the big  
advantages of XML is it's language independence.
There are french, spanish, japanese, chinese people using qemu,  
resulting in imagenames / paths in the corresponding language.
ASCII/UTF-8 is not everything.

simple example:

qemu "/Users/Jernej Simončič/Simončič_image_2.img" -m 128

can be correctly declarated and stored in a XML file while its  
generating problems with normal 8bit text files. Not necessarily on

the config file and the image with somebody...
It's already fun to exchange "normal" textfiles" between Mac

You do realize, that Qemu could easily declare that it's config files are in
utf8? (Though, from my experience with Linux filesystems, the file names
there are just stream of characters, and it's entirely up to the program how
those characters will be presented to the user - the programs/OS doesn't
care if the filename can't be properly displayed with the current user
settings, as long as the name is valid, it can be accessed).

IMHO, XML and charset encodings are beyond Qemu's scope - it just needs to
read in the file, change it's settings accordingly and go it's way. Parsing
XML or dealing with encodings adds too much code for way too little benefit.

> Not necessarily on

Depends on what you use to share the config - many network protocols and
archive formats don't care about the charsets either, and in the worst case
scenario, you'll have to edit the config file and do a bit of
search-and-replace (or simply use iconv) before the file will be usable
(then again, I normally avoid naming my files using national characters -
too many problems with that).

UTF8 is pretty universal, and should be supported on just about any OS (on
Windows 2000 eg. the simple Notepad opens and saves utf8 files just fine).

The script not are the solution that I would want.  

To make a good job with the script is much laborious, and demands to use one 
collection of additional programs (that I think is one bad solution).  

Also modifying qemu, the command line of qemu allow to use the logic 
that everyone prefers.

No it doesn't. All that is needed is the one script.

Unless you mean like a GUI config file editor? But that would likely be
a separate program anyways (and not a script).

What do you mean by that?

I thing that would be useful to insert in the configuration file the options 
for set up the mac address, for assing at one key the combinations of keys 
for execute change of the removable units, and other.
To have for every image one personalized configuration.

That the options of command line having always the priority on the options set 
up from the configuration file.

What do you want (specifically)?

Huh? I do not need any additional program.

I, for one, prefer shell scripts. Config files have no notion of loops, 
conditionals or variables. Shell scripts do. As in the first flame war 
about config files, I fail to see the necessity of config files, let alone 
XML config files.

I'd prefer to have 5 config files and just specify one of them on the
command-line, than having 5 scripts, which run qemu with the parameters I
want.

Well, you can have 5 config files and one shell script.

vqemu -config file

I would prefer to go also beyond, one unique configuration file for every 
image of S.O., and use the command line for overwrite the set up hardcode and 
the set up from configuration file.

Thanks for the confirmation.

Therefore the alternatives are: 
- create several script that they use the command line of qemu 
- modify and maintain one personalized version of 'vdeq'.
- nothing  

Thanks for all, for the comments and the help.

That is not completely true. QEmu is Open Source, and the license permits 
to have your own version ("fork").

Just look at Linux: There is Linus' version, which is often referred to as 
"official", but almost nobody uses it. Most people use a version adapted 
by vendors like SuSE or RedHat.

If you need config file support in QEmu, just do it. If you're nice, you 
send a patch to this list, but you don't have to. If you do, and enough 
people like it, I am sure Fabrice will take it into his CVS, too.
