Hummm even if you convert your current QEMU image to a vmdk file you
still need a vmx config file to start-up a VM in VMWare player no?

Yes, but it's a fairly simple text file and there are links on the net to
show you how to create your own.

Hi Tim!

The last time I tried to compile JQEMU with gcj I had some errors
because the Swing API wasn't fully supported by gcj. But that was a
long time ago and I read that the gcj team have made significant
progress since then so I'll give it another shot this weekend!

In the development version of my Java frontend for QEMU (JQEMU) I've
already integrated the Java VNC client from TightVNC and it works like
a charm without any speed overhead! And it feels just like VMWare...

Since Java is already available for a large variety of platforms this
wouldn't require a big porting effort...

[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?

Sure.  But to 'sell' the project to wider audience, which may be
helpful for its longer term development, a GUI is necessary.
Usability engineering isn't as much fun as hacking the JIT, or 
whatever, but in the end usability counts.  A lot.

For what it's worth, VMware Player doesn't have much of a GUI.
It has about five menu items, a couple of buttons, and maybe one
dialog box.

Good point on that, BUT it's not just about the GUI. It's about an 
"easy" way to install the product and run a given app without the need 
to create/setup a VM - To me that is the benefit of the VMware player. 
However, not much of a big benefit IF QEMU is made easy to install and 
has a nice GUI along with it - IMO.

I've seen several projects ship preinstalled images with prebuilt qemu
binaries, and a script to start it.  It doesn't get much easier than
that.

As I already did in one of my last replies, I point you to
http://www.reactos.org/xhtml/en/download.html
and especially to this file:
http://prdownloads.sourceforge.net/reactos/reactos0.2.9-REL-qemu.zip?download

After Downloading and unpacking that zip-file you will find a .bat-file for 
windows and a .sh for linux to simply start the supplied image. No need to 
setup anything on the computer in question and another pro of using qemu for 
this is that you will not need to have admin/root priviledges (in contrast to 
VMware Player iirc).

Well, qemu does not even need to be installed, it can run from any location, 
if it is distributed in an intelligent manner. The steps required to setup a 
new VM are ridiculus easy as qemu ships a handy tool for creating and 
converting different disk images and a quite good documentation as well.

[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" ;-)

I don't like it. It's just a "player" and the images can't be written.
This means you can run an image but anything you write on it will be
deleted after you close it. I prefer the QEMU -snapshot :-)

use qemu-img to create the disk image.

Yes, that would be mostly useless. But I didn't get the impression that
everything you write will disappear when you close VMware Player.

Their comparison chart says they don't support snapshots, but that's a
different issue.

I would try it out but I understand that Player would overwrite my
VMware installation.

That is just creation. I think Stefano meant that you cannot use the guest 
OS to write to that image.

I understood. I just don't believe it; I didn't get the impression
Stefano was saying that he had actually tried it. AFAIK, VMware Player
writes changes to the hard disk image.

I was able to successfully take my qemu installation of Windows XP,
convert it with qemu-img to a vmdk file, and then boot it up in VMWare
player (and yes, I own the full version of VMWare as well on another
machine, so I'm not worried about the legality if there are any concerns).

I was also able to create a vmdk image from scratch using qemu-img and
install OpenBSD in it.

As I've only owned the full version for about two weeks, I haven't
researched what VMWare tools adds to the picture, but I know resolution
hasn't been a problem with VMWare Player, at least on the XP image.

Performance does seem a bit better than qemu, but I done anything to
quantify this. I'm running on the latest version of Ubuntu.

VMware Workstation 5.5 Beta also carries the VMware Player, yes even
before the Player became official. ;)

Re: [Qemu-devel] Re: VMWare player

[Christian MICHON]

Regarding performances of vmware player vs kqemu/qemu (I'm not
being critical about the figures here, just stating what I measured)...

using a slax-live cdrom, I managed to compile linux-2.6.14 in less
than 3 minutes, when it takes more than 6 minutes with
kqemu/qemu-0.7.2, and around 20 minutes without kqemu.
The test was made using vmdk image format.

But vmware player setup file is over 25Mb compressed, when
kqemu/qemu is less than 2Mb uncompressed :)

Please note that the VMware license terms forbid you to publish
benchmarks without prior written concern. I suspect that you may be in
violation (depending on the interpretation of "benchmark", and whether
you have such prior agreement). One of the reasons I decided not to
investigate VMware further.

But that's not correct. I tried it and could write data on the disk,
shut down the vm, start it again, have the data still there.

I found it a bit ugly that after shutting down the player, my usb disk
was unmounted on the host system - not exactly an effect I want.

I am not sure if it's technically possible and then legal to create
images for running in vmware player with qemu. It would be great,
though, because we can expect lots of people using it, it's perfect for
all kinds of demos, for example those that get distributed on live cd's
until now.
