Does anyone out there have a comprehensive tutorial on installing VMware and successfully managing virtual machines with either xen or vmware?

VMware is pretty simple: download the server rpm, install it, run the vmware-config.pl setup script to set the options and install your (free) license key. Then run vmware locally or from some other machine to access the console where you can create and start the virtual machines. Once created, you can treat the virtual machines like they were separate physical boxes except that they contend for host resources (and once they are up on the network I prefer to connect directly to them with ssh, X, freenx, or vnc instead of using the VMware console. You'll want plenty of RAM on the host machine and if you run several VM's they will perform better if you can spread them over different disk drives.
With VMware you can copy your disk images over to a Windows or Mac host and run them with no changes (Mac version isn't free, though).

This is pretty much what I do. I also keep stock "reference" images for each OS I support and copy from the reference image every time I need to deploy a new VM.
I like the idea of Xen, but the documentation is a little thin especially when it comes to installing useful things like Windows VMs; I don't have the time to solve the problem properly, and I hope that in a year or two I can change this.

So, what would you use if you wanted to / needed to host a Windows 2003 VM on a Linux / UNIX server? I don't / can't sacrifice a whole server for a few ASP.NET aps.

I've never tried this, but someone was telling me that it might be possible to serve up ASP and ASP.net with Apache and mono. I don't know if this is true, but might be worth checking out.

Yes, it is true, but mono or even chilliasp isn't the same as native ASP.Net, it has a lot todo with the COM objects. And as PHP has a lot of native Linux "calls" (which can be "emulated" on Windows + ISS with extra addons), ASP also has some native Windows "calls". The client may need MSSQL as well though, so in that sence extra RAM & CPU is cheaper than a whole new server + monthly colo space :)

I haven't used xen so I can't compare them, but it is easy with vmware server and doesn't require any changes on the host other than installing the vmware package and configuring it. People running xen tend to say that you shouldn't run anything else directly on the host, but this isn't a problem with vmware.

For me I like the features that Xen provides like hot-add memory/processor/storage, live migration, etc. Though if you are not using the commercial version you are kind of limited to the command line for management, if that bother's you then maybe VMware more suites your taste.
Oh, both products can host multiple Windows and Linux VMs side-by-side no problem.

I just started playing with VMware-server-1.0.5-80187 on a 64-bit CentOS 5 system system, and am having some issues with the hotkey switching. Running the vmware-server-console via an ssh connection from a PPC Mac Mini, it doesn't recognize the ctrl-alt sequences, which isn't totally surprising as I'm using a PS/2 Microsoft Natural keyboard on a KVM switch with a USB->PS/2 adapter. When I try running it directly on the CentOS system's console through the same KVM switch, it doesn't respond either.
I have installed SCO Openserver 5.0.6a on a virtual image, and that seems to be working OK (my primary object now with VMware is to have a fall-back when customer's OSR5 system's hardware goes south). I have had at least one situation where it didn't recognize the CTRL-RightButton sequence in an xterm running on the OSR5 image.
This is a CentOS 5 system with ``yum update'' reporting that everything is current.
The system has 2GB RAM.

Once at a social gathering, Gladstone said to Disraeli, I predict, Sir, that you will die either by hanging or of some vile disease. Disraeli replied, "That all depends upon whether I embrace your principles or your mistress".

As I mentioned in the post above, I prefer to connect directly to the guests once their network is up instead of using the vmware console - and especially so for a guest OS that doesn't have a vmware-tools package. I only use the console long enough to create and configure the guest systems.

That makes sense, particularly since I didn't understand that the vmware- tools was something that runs on the guest-os.
So far I have gotten as far as getting the basics configured including the network interface and have it automatically booting when the Linux box comes up (although it's currently hanging waiting for date entry which may require a bit of hackery).
The only way I have found to reliably get mouse and keyboard focus out of the virtual window is to use ctrl-alt-F1 to switch to a character mode, then ctrl-alt-F7 to get back to X11.
Tony Lawrence has some useful information for those of use who are afflicted with maintaining SCO OpenServer systems:
