[Qemu-devel] VMWare player

[John R. Hogerhuis]

Barely on-topic, but since VmWare interop crops up from time to time:

http://www.vmware.com/products/player/

I doubt this is targeted at QEMU, but rather at competing with Microsoft
and VirtualPC. That or they are leaving the low-end market for server
consolidation.

This may in fact be as much VmWare as most people would need. Countdown
has started for the first person to create a system image solely from
freeware "VmWare Player" ;-)

Yeah, it barely on topic. But the .vmx files are extremely simple text
files, and qemu-img creates vmdk disk images. Yes, it's possible to
install operating systems solely withing VMware (this is the correct
spelling, btw) Player, but you cannot install VMware Tools, even with
the appropriate (windows|linux|freebsd|netware).iso file.

That was my first thought when I saw this as well.

I figured as much. I understand some of what VMware tools has in it. Is
it necessary? QEMU is quite usable without special guest-side utilities.

Or perhaps the issue is that VMWare player will not run anything that
does not have VMware tools installed?

I agree. It seems it can do 3 things that qemu currently can't: Use certain
types of host hardware (such as DVD or USB), copy & paste between host and
guest, and support drag & drop. None of these is a major issue (and copy and
paste over qemu machines which are networked is possible).

On the other hand, qemu supports using multiple snapshots, networking virtual
machines together, and its user-net/slirp network support is better than
the host only support that VMware Player has. (qemu also have a primitive
video capture ability via the monitor 'snapshot' command, which captures
video stills of the guest into png files.)

Personally, I'd say that the latter is more likely. VMware gets most of the
big bucks from businesses which want to run hundreds of virtual machines.

Based on the comparison sheet they give, I doubt it is possible. VMware Player
isn't able to create virtual machines. Of course, if you can save changes to
the virtual disk and boot from something other than the hard disk, it might
be possible to use qemu-img to get around this.

[Qemu-devel] VMware Player

[Joe Lee]

I was wondering if there's the capability to have a "vmware player" type 
functionality to qemu. This is just to allow playing or running images 
with out needing to create virtual machines. May this could be a 
separate product. What's everyones thought to this?

Why on earth would we want to make a crippled version of qemu?

AFAIK "Creating" a VMware virtual machine is just making a config file.
qemu doesn't have config files, so your question makes no sense.

Well, I was not thinking or suggesting of a crippled qemu version. I 
asked the question because there are some software
appliances which are pre-built and pre-configured apps that are built on 
a LAMP stack and packaged as a single image
type file. This image file can be downloaded and run on a product 
similar to VMware Player. This is used for quick demo
purposes of an application with out the need to have a full virtual machine.

I am totally new to VM technologies but have played around with VMware 
and the player as well. So, my question was just
an inquiry to see if that capability would make sense on a qemu based 
product that is open source.

However, thanks and appreciated your comments/feedback!

My impression was that these "appliances" are full virtual machines. It's just 
an OS install that's been stripped down and configured to run a single 
application on startup.

What exactly do you mean / what is the actual "use case" for your idea?

Maybe you mean something like this:
http://www.damnsmalllinux.org/usb-qemu.html


Btw. regarding your earlier question about a Qemu GUI similar to VMware: 
AFAIK at least two people have posted GUI patches for Qemu (look in the 
mailing list archive); so far there has been little response to that, 
and I suppose that these patches "just" need testing and some feedback 
(as they seem to be pretty intrusive, with changing the video output and 
the input handling stuff).

Oliver

Re: [Qemu-devel] VMware Player

[Joe Lee]

You are right, and the idea is that the person have full interaction 
with the application environment including the underlying LAMP/WAMP 
stack  that has been packaged. Users that want to quickly run and 
test-drive the appliance may not really need a full VM type application. 
Just something that could quickly run the image (appliance).

An VMWare player "appliance" is really just a disk image & config file.
Running a disk image in QEMU is just a matter of executing

   qemu -hda /path/to/image  

Perhaps adding "-m XXX" to set increased  RAM.

This is no harder to do than using VMWare player

  vmplayer  /path/to/appliance

Since QEMU already understands VMWare disk images, there's even a good
chance that QEMU can run a VMWare "appliance" image itself. So it looks
to me that QEMU is already on a par with VMWare player in terms of being
able to quickly & simply test 'appliance' images.

If you are looking at something like rpath/rbuilder then qemu will run
those images that
are packaged as raw HDD.  If you set the options right the running
image has network access also.  I am trying to figure out how to get
the network access options working
for the windows version of Qemu.

To add to this and my previous mail, I'd like to point to ReactOS, which is 
distributed in various forms for simple testing, including a version bundled 
with qemu: http://www.reactos.org/xhtml/en/download.html

With regards,
Jan

PS: As qemu is really small compared to VMware Player, it poses only very 
little overhead to bundle it with the image (one could even hack some sort of 
selfextracting executable qemu+imagefile)

Sure.  But to 'sell' the project to wider audience, which may be
helpful for its longer term development, a GUI is necessary.

Which is exactly why I like to wrap up things in a really small Tcl/Tk

Your right! the keyword is "some" but not all. I think if QEMU is to be 
adopted by the masses it will need to come up with a quality 
GUI-Frontend. However the CLI can always be in place for those who want 
and prefer to use it. Otherwise, I think most users will prefer to stay 
with VMware and especially that there VMware player AND VMware server 
edition is now FREE.

I appreciate the effort that some are making to develop a GUI for QEMU - 
There's a few project I see that trying to achieve this. But, I wish 
they all could come together and work together to develop a nice GUI. I 
would like to see a sub-project exist in the QEMU site so all can come 
and contribute to that effort.

You're right! However, as Julian pointed out: it is less than fascinating 
to work on a GUI, _especially_ if it is for the masses who tend to 
criticize without contributing*Footnote 1*.

So, unless the people who want a GUI so badly do it themselves, I think 
they will have to hire somebody to do it for them. Remember: since it is 
free, there is customer, and therefore no customer can be lost!

IIRC Fabrice has (quite some time ago) stated that he'd like to see a 
Qemu GUI that is integrated into the app (ie. not an external 
application that only captures the Qemu window), and also that the GUI 
should be done in GTK (though I'm not sure about the exact wording, so I 
might be spreading false rumours here ;)

This would mean that the next steps for a GUI would be to "migrate" 
input event handling and graphics output from SDL to a GUI toolkit like 
GTK. Incidentally, that is more or less what the patches do which are 
floating around on the mailing list. I guess the reason why they were 
not integrated in CVS is that they are quite big and intrusive, and that 
Fabrice waits for some more feedback and testing of the patches.

So, in the end, testing is probably something that anyone can do who has 
enough spare time and wants to put that time into developing a GUI for 
Qemu :)

Oliver

I am not sure I agree if that thought. It really depends on the mission 
or goal of the project. In the case for QEMU, I am not sure what its 
goal/mission is. Is the project just to scratch an itch to server a few 
people who needs it? Is it to fill a void over what exist in commercial 
software? Or, is the intent to develop something FREE and then offer 
some support service around the product?

As far as users criticizing, that always going to be the case in Open 
Source - Show me a project where users don't criticize. As far as 
contribution goes, not everyone has the talent and ability to contribute 
- Like me. The way I see it, criticizing (when done in a constructive 
way) is not a bad thing. It is what drives the project when others share 
there views on features/functionality good or bad!

As far as I know: Fabrice started the project because he had this idea 
that translation should be faster than interpreting, and not much more 
difficult.

He proved his point. And many people actually use QEmu, which is all the 
better.

Yes. And developers will always complain about those who profit and don't 
contribute.

I doubt that. You _can_ contribute. You actually do it right now.

This is a contribution! By telling what is important to you, you 
contribute to the future value of the project (note that I say "project", 
not "product"...)

There is a subtle point-of-no-return though. The story I was referring to, 
was where a person did not contribute, but instead called people names if 
they did not do what she wanted, which was effectively to work hard and 
for free. Which is just not fair.

I do not know VMware. Anybody? I would be interested, too, to know how 
complicated that frontend is... Should not be too difficult to reproduce 
it in Tcl/Tk (with a proper Tcl script as config format).

Geez, why not ask for world peace while you are at it.  One GUI?  So
which toolkit?  Pick Gtk and watch the K folk whine.  Ok, so KDE it is. 
Oops, now the Gnomes are all over ya.  And of course since I suspect a
non-trivial percentage of QEMU users are on Windows, Solaris, etc. they
ain't gonna like either of those choices much.

Face it, putting a GUI on something like QEMU is going to require at
least a one per desktop/platform effort.  And that can best be kept with
the GNOME/KDE/etc software repositories because they require constant
updating on the schedule of the rest of the desktop environment to stay
current.

Think of it like mkisofs/cdrecord/growisofs/cdrdao vs the abundance of
graphical front ends that all make use of them.  Nobody has to totally
reinvent the wheel because those solid CLI only parts can be reused by
each project and each graphical environment gets a totally native (ok,
several) GUI CD/DVD authoring/burning program instead of one crappy
ported program.

There are some screenshots of "VMware Workstation" at
http://www.vmware.com (see Products menu). Didn't find screenshots of
"VMware Player" there, but Google image search shows a few for "VMplayer".

If you are familiar with Tcl/Tk, maybe you could give some hints on how
to embed the Qemu window into such an app?

I think there are only two ways for making a GUI:
- - embed the Qemu SDL window into another application (there seem to be
various hacks that do this under X11; not sure about Win32)
- - replace Qemu's SDL part with some GUI toolkit (GTK, Tcl/Tk...)

I guess the second way is quite a lot of work.
The first way is a bit "hackish", as eg. events have to propagated from
the GUI app to the Qemu window... how would this work with Tcl/Tk?

Probably with the second way it would also be difficult to display
real-time status info in the GUI (eg. guest CPU load, guest HDD
accesses, network accesses).

Oliver

Thanks. But I would like to know if there is a developer who has 
experience with the GUI. It is one thing to see the GUI, another to work 
with it.

I would go the easy way: just before starting QEmu, hide the Tk window... 
no need for embedding.

Yes, I know this is a lame answer. But I am quite certain that most users 
would be happy about it. They do not *need* to do something fancy. They 
run the virtual machine, shut it down, and that's it.

Heh :) that's what the current Qemu GUIs do already (many of which are
mainly configuration GUIs). Thinking about it, at this point maybe an
"official" configuration file format would be useful for all frontends
and would really help unifying the GUIs (there has been a lot of talk
about this already anyway).

Re: [Qemu-devel] VMware Player

[Rick Vernam]

QEMU leaves me with very few 'itches to be scratched' ...

The basic tasks that a QUI should confine itself to, IMO, are already pretty 
darn easy - define/manage a VM (via a shell script for me), start it, stop 
it, pause it...etc..

Even so, I've been thinking about this for some time - months probably...
What I'd develop, if I were to undertake such a task, is a very simple app 
that can start qemu according to some configuration, and simply hook into the 
monitor to issue such commands as sendkey, stop, cont ...etc ...

I do not imagine a need to have this app embed the qemu VM in itself, only 
start it & hook into the monitor.  Besides, I don't want to loose precious 
real estate - I like the window that a running VM is in just how it is - no 
changes.
I've used VMWare in the past a lot.  I found the toolbars & menus to be 
nothing more than clutter & annoyance.  The majority of the work I do with a 
VM has everything to do with the VM, and nothing to do with things that can 
be done with an additional GUI, however it would be nice to have one for 
simplifying those extra tasks...

Specifically, I imagine something sitting in my Sys. Tray.  This Sys. Tray 
icon menu thing would have options to invoke qemu's monitor commands for easy 
access ...or a list of all VMs, each with a sub-menu (I'm thinking stop, 
cont, loadvm, savevm, commit, usb stuff, change device x).
Also, I can use the Sys. Tray Icon to bring up it's window with all the 
niceties to create a new VM, manage existing VMs...etc.

Right now, I have a shell script that has the 'configuration' of my VM - 
changing of that 'configuration' would need to go in the GUI.

I also use the monitor thing for stop, cont, loadvm, startvm, commit, usb 
stuff & change device x - that would need to go in the GUI.

Beyond that, what does more bling really bring to the table?

I glad to see many people sharing comments and making suggestions since 
this thread topic started. I seems there enough interest to have a 
GUI-Frontend for QEMU. I am hopeful this can lead to getting something 
started.

I'd like to see a poll from people who would be willing to participate 
and contribute to getting something started.

I'd absolutely love to.
Although I have no experience with Qt, GTk, Tcl/Tk ...etc (only win32 GUI 
stuff, which I haven't done in years).
Nor do I know anything about qemu internals...

WxWidgets (www.wxwidgets.org) provides a nice way out of this - provides
a uniform API for the application developer, and local look-and-feel for
each platform.  WxWidgets can sit on gtk, motif, x11, win32, mac, cocoa
(doesn't appear to be a qt backend yet, but no reason there couldn't
be).

Firstly, we do not have to start from scratch. There are some excellent
examples of gui's as separate projects. We just need a benevolent
dictator to "select" one as a concept, so the project will focus on a
main branch.

I will put forward my vote in advance for gtk. Cross platform, always
free, no strings attached. 

I am not a very good programmer. I could do a simple gui is one day, a
comprehensive one may be a solid month. But the quality of my code would
not be as good as the existing options.

I tried qemu-launcher. Loved it, then upgraded qemu and it no longer
works. Hence I would like the gui to be in the main project, so they
stay synchronised.

Fortunately a lot of the work has already been started in the separate
projects. It would be better to select one and build on it, than
starting over.

I would never advocate taking away the text based interface. That in the
MS domain. But an installer + default gui will go far.

Yes, there should be abstraction between the UI and the VM, but I think
that the approach taken by xine, gstreamer, cdrecord, cdparanoia, etc.
is much cleaner.  You could still write a frontend with WxWidgets...

I think it would be best if QEMU didn't depend on any particular
toolkit, and that includes WxWidgets.

I thought I share this with you all. I have been looking into XEN lately 
and someone has developed a GUI-Frontend for it. Here's the link below 
showing images for the GUI interface to manage xen. A similar type GUI 
interface could be done for QEMU.
I wonder want programming tool used for it.

GTK. Since XEN is already limited in scope to a Linux host, it makes (sort 
of) sense.

I was suggesting WxWidgets as a way to avoid writing separate gui
frontends for each platform (that's what WxWidgets is for). I wasn't
suggesting WxWidgets be embedded into Qemu (or the other way around for
that matter).  If you want a pretty controller app and you want to
avoid cross-platform issues WxWidgets does a lot of the work for you
(much more than just gtk for example).  In particular I was responding
to the statement

I don't see any reason to hack up qemu just to put a pretty face on
it.  VNC support already provides an easy way to place the guest screen
wherever you want if you don't like the SDL window (although I think
SDL remains the best choice for the guest screen).
http://code.technoplaza.net/wx-sdl/ talks about combining WxWidgets and
SDL, although I don't know if that's useful.

you're putting c++ inside the qemu source tree when it is not
needed (yet).

if SDL is common to most guest screens: I agree with you
that the gui/toolkit should overlay the SDL.

Yet Fabrice mentionned months ago this was not his
intention, so we should respect it and (hopefully) close
this long thread.

Close the thread? Please not - I think it's good that many people posted 
their ideas about a GUI, and maybe there will finally come some 
agreement about the techniques and libraries that should be used.

And if Fabrice doesn't want C++ in the tree (seems a bit reasonable), 
then there's still GTK. And if it is too difficult to install and run a 
GTK GUI under Windows, then a native Windows GUI is still possible 
(after all, the Mac OS X version uses a native GUI toolkit as well, so 
why not do the same under Windows, and use the GTK frontend under all 
other platforms).

Btw. it would be interesting to know what features would be required to 
get a GUI into the Qemu tree, and what would be a total showstopper... 
Maybe the people with commit permission could comment on this :)

Regards,
Oliver

Perhaps I'm still not making myself clear.  I did _not_ suggest that
a WxWidgets GUI be integrated into QEMU.  I assumed we were all talking
about an independent controller app to provide a pretty clicky-button
way to start/stop qemu instances, provide console and serial i/o
terminals, that sort of thing.

The only thing that may be worth thinking about is a way to redirect
the SDL output from QEMU, if VNC proves too slow.  Even that would only
be if you want the QEMU screen to be embedded in the frontend, and to
be honest I see no need for that.

The FLOZ project
http://www.oszoo.org/wiki/index.php/Free_Live_OS_Zoo

Uses the tightVNC Java applet to connect to QEMU instance.
QEMU on the server is CVS, but lacks the last vnc.c patch (I'll put it
on when I have some time).

This really is too cool ;)

What hardware is it running on?

Currently we use a dual xeon 2.8 GHz with hyperthreading and 2 GB
physical RAM.
