Remember me from Be days? (maybe not)

Only one point to quibble with: In your article blurb, you state that "Bochs... are applications that virtualize the x86 hardware..." Well, I know that you clarify that in the article, but the blurb is incorrect, since Bochs is really a full-blown emulator, not a "virtualizer" like VMWare. I wish it were! What's up with Plex86, anyway?

Anyhoo, thought you might want to know that I was able to install, boot, and RUN BeOS R5 in VMWare 3.5 beta. Only a few glitches, such as no color (stub VGA as expected), and wrong CPU speed ID (probably a loop during the boot process, gets hosed by the VM), so it reports my Atlon 1.4 as about 60 MHz, and of course the BeOS system clock runs like I'm in a future-going time machine.

I suspect that VMWare doesn't handle very well the MSRs that BeOS uses for high-resolution timing? Too bad.

I added the "or emulate" blurb, but there is not a real issue, because I do clarify it later in the article.

>What's up with Plex86, anyway?

AFAIK, it is dead, right after Mandrake laid off Kevin.

>BeOS R5 in VMWare 3.5 beta

Unfortunately, I don't have access to this unreleased version. I was able to boot the BeOS installer with VMWare 3.1, but BeOS could not see the virtual hard drive. I was more lucky by booting it directly from my real hard drive, from its BFS partition. But it is extremely slow for the reasons explained in the article and in the comments here:

It wasn't VMWare 3.5, it was VMWare 3.1 BETA, which is "older" than what you tested, most likely, since it's no longer in BETA.

BTW: How to get BeOS RUNNING in VM 3.1... Select "Other" as the guest OS, then make sure that "Enable RAW Access" is checked under CD-ROM/DVD-ROM options. It worked perfectly for me, just booting & installing directly from my R5 Pro CD!!

Just a little note from my experience running VMWare Workstation 3.0 and 3.1 under Linux (RedHat 7.2), sound works very well under WinXP, RedHat 7.3, and FreeBSD. IIRC, VMWare creates a virtual Sound Blaster 16 which most OS's have built-in support for. Watching streaming video on windows media player running in vmware nets extremely acceptable performance on my athlon 750.

> VMWare doesn't work in windows 98, right?

No, it does not make sense to support a FAT32-based OS. Even VirtualPC has different binaries for Win9x/ME and for NT/XP/2k. You see, you can't have more than a 2 GB file under FAT32, which means that if you want to install Red Hat 7.3 which is 5 CDs or XP which will need 3-4 GB to work efficiently with it, you are out of luck with Win9x/ME. Plus NT/XP/2k support more features and stability, something that VMWare supports and welcomes. We should not forget that VMWare is mostly a professional tool, it is not directly destined for end users.

How do you think AtheOS and SkyOS are running under VMWare in the screenshots? VMWare will automatically expose the VESA if the VMWare virtual graphics card drive is not installed or supported under the guest OS.

I'm currently running NT 4.0 Workstation (SP6) under Slackware Linux 8.0 with a 1 GHz PIII with 256MB RAM with VMware Workstation 3.1 and it runs quite nicely. The only problem I've encountered is some weirdness with going to full-screen mode...sometimes it takes a few tries at the button to get it to actually switch.

Setting up VMware under slackware is a bit weird though...due to the different init file layout. Basically, you have to make an init.d directory under /etc/rc.d and then populate it with rc0.d to rc6.d directories, then install VMware. To have VMware's startup actually run on boot you need to add /etc/rc.d/init.d/vmware to one of your startup scripts (rc.local is a good choice). All this is documented on VMware's site as well...

Probley... but unless you have a 1000 Mbps network, or faster, and a really nice server I have a feeling this will be a really slow setup. VNC isn't very fast... but that could be just me.

I needed a quick way to test something with Linux without having to have a dedicated machine to do it, so my choice went over vmware 3.1

'Real Machine' Specs:
AMD Athlon XP 1700+, 256Mb RAM, 2 Intel NICs, WinXP PRO

'VM Machine' Specs:
128Mb RAM, 2 NICs, RedHat 7.2

I'm running 1 VM NIC bridged with public IP from my ISP and the other to my intranet. KDE runs very fast and with sound
Currently this VM is hosting a DirectConnect Hub Server with 450 users witch translates to 450 open connections and 60+ KB/s upload modem traffic 24/7. No crashes for a month testing now.

The only problem I had was the logfile vmware uses: 5,7Gbs in 4 hours? some fast text log to screen from DCHUB caused BitBlk errors in vmware. No option to disable logging?!

I've been running VMWare for quite a while with great success. When faced with the choice of which os to be the 'Host' and which is to be the 'Guest' os, my own views might help some of you.

The issue is that with the typical desire to run NT and a *nix system together on th same hardware, one sees that VMWare is purchased as one of two different binaries: as a Win2k/NT 'Host' , or as a 'Linux' host. For at least two reasons one is *strongly* advised to use the Win2k/NT version of VMware as the Host system, and then to install one or more linux/unix's , etc, as guests. The reasons follow:

1) With Win2k/NT as the 'base' ie, 'host' system installed, one finds that nearly all hardware is available at ALL times .. We love linux, but the fact is we have hardware that just will not run *yet* in that environment. (Eg: Nikon 4000 filmscanner, which is a pure 'firewire' device). Working in Linux (guest system) lets me immediately switch back to the host NT5, and i'm golden. I get full support of all hardware whether linux drivers exist or not. The *host* system MUST support what you need in order for the guest system to have any chance of accessing it. Period.

2) All instances of MS os's installed (as guest or host) must have costs a license fee. I think that having NT5 as host satisfies any inclination to add multiple 'guest' NT systems to a Linux host. (yea, this is a 'soft' reason, cuz ya might never dream of having two MS os's)

I use NT5 (Win2k) as host on this 512meg dual PII with very satisfactory results. Photoshop 6, the Nikon scanner, 8 USB ports, digitizer, dual monitors, and a mix of scsi and ide drives (including CDR and a CDROM-DVD disk) all work fully under the Win host. As an example of what i've said, DVD drives are not supported in VMWare yet, but i can use it fully in NT. (unfortunately, VMWare does not support SMP !)

I'm nearly always in my trusty linux (SuSE 7.3) which i manually upgraded to the 2.4.18 kernel. Today i effortlessly started that Suse virtual machine and caused it to boot from the new SuSE 8.0 cdrom disk (the nice SuSE DVD disk is useless in this system, as i said.) The upgrade was a snap: kde3 is great , kmail is beautiful, and so far it's a 'go'.

(afterthought: re: dual monitors: the full use of dual monitors for each os (NT and Linux) needs comment: my host NT fully supports both ViewSonic flatscreens. If i booted a purt linux boot, (which i can do via SystemCommander) then linux, too , sees both monitors fine. However, booting to the NT5 host only lets the NT use both monitors fully. Linux guest starts up in an NT5 window, which can be dragged to either of the 2 monitors and behaves fine. However, guest os's run much faster in 'Fullscreen' , and if that linux window is popped up to fullscreen, it instantly comes up *only* on the first monitor, no matter where it's 'windowed' instance existed.. a little quirky, but in no way a problem. When fullscreen on monitor 0 , the rest of the NT desktop is seen fine on monitor 1. Fri, 10 May 2002 02:21:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? I've tested both VPC for Windows and VMWare. From my experience VPC is more compatible with most OS. Most OSs I tried installed and detected the hardware (including the sound card) without glitches. The list of OSes:
1. Linux - Mandrake 7.2 thru 8.1, Trustix 1.5
2. OpenBSD 2.9
3. Windows 98, Windows 2000 Server
4. Dos 6.22 (to run Master of Magic )

Contrary to the review, I find the GUI performance in VPC is actually better than VMWare. Overall performance is not that great, sometimes it will stall for a while (probably due to disk I/O).

The latest VPC 4.3 has a built-in remote desktop feature which allows you to use VNC client to view your client OS's output.

I have VirtualPC for Windows, and sound emulation is pretty good (but by no means perfect). First off, sound emulation under Linux has known problems and is very difficult to get working. I've been trying for a while and still can't get it to work. Under Windows it is good. Under DOS it is surprisingly good. All you need to do is add the SET BLASTER= line to your autoexec.bat and nearly everything works. For some reason, however, none of Creative Labs SB16 (the sound card VPC emulates) drivers detect the card. But this does not matter, as most (if not all) DOS programs/games do not require drivers to be loaded. There's this program called QVPRO (quickview pro?) or something. It runs under plain DOS and plays nearly all types of media (MPEG, AVI, DIVX, QUICKTIME, WAV, MP3, etc). Under VPC, every type of file I could find and test worked perfectly. You can download a 30 day free trial, if you didn't know. Fri, 10 May 2002 05:47:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? Just an FYI.. in VMware's FAQ it mentions that you should install RedHat in text mode. The problem is that until the guest os toolkit is installed, X will be very slow.

Once the OS toolkit is installed though, it's lightning fast. Fri, 10 May 2002 05:53:00 GMT donotreply@osnews.com (Anonymous) Comments http://osnews.com/thread? http://osnews.com/thread? I got onto the virt pc bandwagon the day the beta was
publically announced... (or so).. and ended up picking
it up for a reduced rate a month later. I knew that vmware
was a much more mature product, but I also know that vmware and bochs were dead slow.

to me, virtual pc blew away vmware in terms of ease of
use, price and speed.

for the cds and floppies, can't you "bind" them to the virt pc? vs sharing them with the host?

I run all my system now through virtual pc -- because I use a type of home-grown "ghost" imaging of the base os installs of win95, win98 and freebsd... although I haven't had to re-install the freebsd :->

Basically, my 900mhz laptop running virtual pc hosting freebsd is FASTER than my 500mhz celeron running freebsd native. Oh well.

So, anyway, my current laptop has 512mb ram, next will have 1 GB. disk is 20 GB or so, next will probably be at least 30. So with this much ram and 128mb to each virtual, I can run everything I need from one machine.

I see vmware as a much more mature product and ready for use in business for server farms and the like and probably both vmware and virtpc would be good/great for home use. I simply liked the easy of the interface and speed of virtpc.

The 3.0 version only supports win98 and 95, but the newer version 4.0, now includes support for ME and additional hardware support.

It is definately more virtualized than VMWARE, and application performance seems better based on my limited experience with VMWARE.

For comparitive sakes though win4lin might be better compared to the former VMWARE "Express" version.

I believe I paid $80 bucks for my copy.

I am running VPC under eComStation (OEM version of OS/2) as host and a variety of operating systems as guest. I do not see the CD/floppy drive problem you described. We have tested VPC on a variety of hardware. The "slowless" you experience might actually be caused by the dual processor (don't remember if you were runnign NT as host, or Linux as host). The current version of VPC does not take advantage of SMP and having it around might actually slow things down. In any event, I would not recommend using the sub-1GHz processors to run it. My thinkpad T22/900 is ok for a demo machine but things become very usable on my Athlon 1900+ system.

We are doing a number of things to boost the performance of runing VPC under eCS. You didn't mention if you are using the shared folder feature of VPC but we found that performance is generally much better by not using that feature. In fact, if you can minimize or eliminate local I/O, you will get a tremendous boost in performance. For instance, we are running the host diskless - remote booted from the server and the Guest "thinks" that it has a local hard drive but all I/O are actually networked I/O - cached at the server.

As I understand it, VPC's method of virtualization makes it more compatible. We have been throwing all kinds of operating systems that we can find at VPC and everything works. The only one I didn't get to try is BeOS (I don't really have a need for that).

I have no way of comparing VMWare to VPC since VMWare does not support OS/2 but I find VPC very usable - given the proper hardware.

I'd like to reinforce the comment on win4lin - I've been using it for about 2 years now under slack 7.0 (with various kernels) to host a win95 system. It's much more lightweight than vmware (it'll run on a 24Mb 486-100), and on midrange machines, much faster. In comparison Bochs is technically intereting but glacial.
