Win4Lin allows you to run Windows on a guest Linux environment. It works well, but does it really achieve near-native Windows performance as stated by Win4Lin?

(Attention: the following post is probably the most useless of the day)

I am am quite eager to find out if games work at all in this fashion. If it does... I might actually take this for a test-drive. Has anyone been using this, or any emulation software for Linux?

I cannot imagine that this would be working well. Especially because the new games even let the most dedicated systems sweat.

For a linux user that really needs to use (i have a hard time coming up with an excample) a windows application however... Why not.

Update:

"Any application built upon the DirectX graphics library won't work under Win4Lin owing to its lack of built-in support."

So not really.

It would have been more interesting to see the booting times and others, compared to VMware...

You don't need to be a genious to figure out that it's slower than a native windows (thou there is "how much?" )

Well a great review anyways, I tried to install win2k with this a month ago, but it complained that the media isn't bootable (my win2k disc might be broken..)

How about running Linux under Windows?

http://wiki.colinux.org/mediawiki/index.php/Main_Page

It takes some effort to set up the networking but the performance is good.

I am running Debian but there are a number of other supported distros. All the Linux application I have tried have worked including google earth. The main problem is that you need to install a windows X terminal like Cygwin's XWin.

I have used both recently on the same machine (actually, QEMU + KQEMU module, but it's the same whing without pretty wrapping), and they both seem roughly the same, VMWare perhaps getting a slight edge due to some additional tools that can be installed in the guest OS to help things along. Don't have any hard and fast numbers, just gut feeling.

Also note that the horrendously slow install times noted in the article are not aparent in VMWare Server.

In the end, I've been able to run Windows XP Pro at native speed on my machine with the regular visual stuff turned on, but that's mainly a credit to my machine. It's great for trying out different OS's like FreeBSD and Solaris that I would not readily install on my home machine for learning purposes.

All you Windows users that want to try out some version of Linux but are afraid to actually put it on the hardware, I heartily endorse giving VMWare Server a go. It was fairly straightforward installing it on Linux, so I imagine it's quite easy to do in Windows
edit: or as CDDK states, colinux.

ya thats actually a really intelligent idea to use VM tools to try out linux. It is a lot easier to do virtualized linux than deal with wiping your Harddrive.

If I ever try out other newer linux versions (besides Fedora) I will make sure to use these VM tools...

I get the feeling this guy did not actually READ the article.......

If you want to try a Linux distro without messing with your Windows installation try a Live CD or Live DVD. Boot Linux up off the CD/DVD without having to install it (e.g. Knoppix at http://www.knopper.net/knoppix/. Some of these Live CDs are useful tools to have if you are traveling or you you want to recover from a Windows drive that won't boot (e.g. http://www.sysresccd.org/). You can be up and running Linux as fast as you can download a 650MB ISO and burn a CD.

You can also be up and running Linux on Windows using the free VMware Player software and one of the free virtual appliances at http://www.vmware.com/products/player/. A lot of the more popular distros are avaialble as well as various BSD distros. Or, if you like hacking, you can roll your own. See, for example:

I have a dual boot OpenSuse 10 and W2K home installation at the moment. This is still a bit of an experiment but I'm impressed enough that I'll probably upgrade this to SLED 10 when it is available. I've been a long time Windows user but I just can't get excited about Vista. It's very late, stripped of lots of promised features, has a high hardware requirement, and it's expensive for what it is. Why do I need this? At work I got upgraded from W2k and Office 97 to WXP and Office 2003. And I'm hard put to see that I got anything out the change. I'm already running a lot of Open Source apps on Windows that all come in Linux versions. There are a few apps I need that won't run on Linux so I'm probably looking at using VMware Workstation or maybe Parallels (http://www.parallels.com/).

If you want to get a taste of the forthcoming (July) Suse Linux Enterprise Desktop 10 take a look at these videos:

The cool XGL desktop will run on a cheap $30 Nvidia card unlike Vista's Aero.

Open Suse 10.1 available here (but this was just released and there are some issues being worked out with the package update manager...):

They're getting there...

I would like to see WINE, or crossover office, cedega, compared to win4lin. Since WINE is a translation library allowing windows apps run natively under linux, it should be a lot faster. It would be nice to see how compatable it is with desired apps and how well the run. It would also be cool to see how efficient the directX to openGL libraries work.

Yes, liveCD's are great and they are a great intro, but my suggestion for using a virtual machine is more along the lines of testing out the installation process (as streamlined as it is now, in most cases) as well as daily use and software install. For most users who are kinda curious about Linux, i'd say the following migration path is a nice way to ease into it...

LiveCD: get to see what all the hoopla's about, get a feel for interface and software
V
Virtual Install: become more familiar with the management/daily use aspects of Linux
V
Dual Boot: furthering the daily-use experience, this time at full-speed and full capability

If you need to learn it fast, for example for work/school purposes, I'd say get a friend (I or any of the admitted Linux fans who use this forum will do) to help setup a dual-boot and set the default to be Linux. That way, when you turn of the machine and just walk away, you'll be gently prodded into using Linux for daily stuff.

My $.02

edit: Fixed a typo or two

I can tell you (again, no hard numbers here, just gut feeling) once I got it installed and running* under WINE, GTA Vice City ran just as fast as it did under Windows with a glitch here and there. I haven't yet installed it on my VMWare'd XP Pro, and if you'd like I can give it a go and report back, but I have a feeling it'd be noticeable slower due to the increased (although optimized) overhead.

Breakdown from my experiences:
WINE - usually fullspeed or sometimes faster, but can be painful to set up and glitchy
Cedega - no experience, ask others
VMWare/QEMU+KQEMU - 75-90% full speed

*required running down various Windows DLL's of specific versions and editing the WINE config file. For any Windows users that wish to point to this as a reason that Linux isn't ready for primetime, try installing Cygwin, then any Linux app. API redirection or whatever you wish to call it ain't easy but it is fast.

VMWare
- is very user-friendly
- has GUI wizards for anything you might want to do
- is also slightly faster than Qemu.
- Supports a very wide range of guest operating systems (like Mac OS X)
However,
- it abuses the host Linux system (nice -10, lots of kernel modules) disrupting other native applications
- it requires root privileges to run
- Uses many kernel hooks that may break with recent Linux kernels (gfx drivers suffer from this too).
- is proprietary software, not open.
- needs a license to work, which can expire at any time and demand to be renewed.

Qemu by contrast
- is a little slower
- you need to fiddle with its command-line options
- you need to compile its simple KQemu kernel module and insert it by hand
- Does not support many guest operating systems. (no Win Vista yet, no Mac OS X)
BUT
- it's completely open and free
- runs with a simple user account
- runs smooth and does not abuse the host system
- it will NEVER expire, never bother you with licenses and stuff :-)

I vote for Qemu anytime, unless performance is a deciding factor or you want to host a strange operating system.

Running games and other 3d applications is not practical on any of those virtual machines.

Dual booting is a PITA: rebooting takes time and you usually need programs from both systems.

colinux is FAST. Faster than any virtual machine, BUT it is also insecure (your Linux kernel has complete control over all your windows disks)

Wine is nice if you only want to run 1-2 small windows apps but it becomes a problem as your needs increase.

A heavy Linux user's two cents.

Performance under VMware is actually not bad. My Athlon X2 runs Windows XP on VMware Server 1.0.0 (Gentoo 64 host) pretty well- just a touch slower than my 2.2GHz Pentium 4-M notebook does natively.

However, do NOT try to install Vista x64 using VMware to test it! You do not have enough power to do so if your computer cost less than 5 grand and you got it yesterday. You need at least 4GB of RAM, 4 fast cores, and a very fast HDD array. 2GB RAM, my X2 OC'd to 2.5GHz, and a Raptor did not even come close to cutting it. I even have 6GB swap striped across both the HDDs in my system and still had a system load between 12 and 19 and change (!!) while running Vista. Oh, and I was swapping about 1K pages per second even though I only gave Vista 1GB RAM. Vista on VMware on my desktop acted like the PII-300 with 192 MB RAM running XP SP2 that I have to use at work.
