So you are being accidentally persistent then? And not doing it deliberately?

Why are you trying to use an old vmware version on the almost very latest 
kernel version? If you know anything about the kernel development process and 
the vmware development/release process, you will know that what you are trying 
to do is just never ever going to work.

SO STOP TRYING!!

Do one of these options:

1. Use latest unstable vmware with the last unstable kernel that builds
2. Use stable vmware with latest stable kernel that builds

There is no third option. Stop looking for one.

Do any of the emulators work with 2.6.30r5 kernel? I am not bound to only
vmware, what about XEN,  VirtualBox etc...

VMWare 2.x is your best bet....

VMware Workstation and VirtualBox work with ~gentoo-sources-2.6.30 here.

As I said in a different thread, that version of virtualbox-modules will
build successfully against kernels *older* than 2.6.29.

I don't use vmware but I do use virtualbox every day and I love it.
It's extremely fast even compared to kvm, which I also use on my newest
machine with hardware virtualization support.

I suggest you fetch the latest stable binary package from:
http://www.virtualbox.org/wiki/Linux_Downloads
(choose the "All distributions" package) and run it, which will also
build and install the vbox kernel modules automatically.

It's very easy, quick, and simple. It even comes with an uninstall
script if you don't like it.

Some questions, please:

1. How would you contrast these two packages for "security" use?

(I'm planning on setting up a server on my desktop, and would think
running it in a VM would be appropriate)

2. Should someone get a shell in either of these VM clients, would they
even be able to determine that they're not on hardware (using full
virtualization)?

3. Do the VMs see themselves as being on a LAN (e.g. 192.168.x.x), or do
they actually share the hardware with the host?

4. Do you communicate with them via, e.g. SSH and/or X?

Thank You (been hoping to find someone who knew both VB and KVM :-) )

1) Security is for exploiting
2) If they are well versed on the drivers that virtualization technologies
use, then yes they can tell they are on a virtual machine and not on
dedicated server.
3) You can bridge network connection "physically on the network" minus the
nic of course
4) Virtualization servers "VMware, VirtualBox" offer clients to connect to
the servers, ssh, sftp is also possible as is done with regular servers.

I'm not a computer professional, so I'm not the best one to give advice
about security.  I can tell you that both vbox and kvm are built on top
of a qemu base so they share a lot of code.

The principal advantage for vbox is its nice gui interface to the massive
list of qemu command-line options, and its highly optimized virtual graphics
driver, which is what make vbox faster than kvm.

If you don't need the fancy fast graphics driver (for your server) then
it's just about a tossup between the two, both being based on qemu.(Oh,
but vbox is very fast even without hardware virtualization support, and
kvm isn't.)

Networking is anywhere between trivial and a nightmare, depending on what
you need it to do.  Both by default "just work" when a guest is talking to
the internet via your host machine, but then it's difficult communicating
with the guest locally.  There are ways to do bridging, firewalling, making
a virtual lan between guests, and lots of fancy stuff, but then you really
need to know how to use all those fancy options (which I don't).

I use both of them to run Windows guests using the default network settings
(no custom configuration whatever) and I use samba on the host to share files
with the guests, which is very easy.

I suspect that running a virtual server might require some network tweaking
to make a decent job of it, but I'm only guessing.

I hope some experts can add to or correct the above.

Well, not an expert by any measure here, but I have been using Vbox
for about a year (with a variety of both hosts and guests), and I will
mention that networking with it is an absolute breeze 9 out of 10
times. Bridged connections, internal networks (client to client
visible only, great for hosting mysql on one guest and apache on
another), host-only (internal with a virtual connection into it on the
host, only worked with this on Windows hosts), NATed connections
through the host (not optimal for servers, but the default and great
for initial builds and 'simple' work with a guest). I also run 3-4
guests at a time with no problem on my meager little Core 2 duo,
3.0ghz, 4gb ram.

I tried it, but on my box it can't detect either of the DVD drives, so I 
can't install a client.

I may try installing it on my local server and see if that's any better.

Hm, never tried that.  The reason is that I've always just used an iso file
'mounted' on the virtual machine's CD/DVD player to install a guest.  Most
open-source OS's supply the install disk in the form of an iso file, and
to install Windows I create an iso file from the original CD/DVD first.

The trouble is that there isn't a CD or DVD player on the vm at all; 
only /dev/fd0, which isn't a lot of use to me.

You've confused me there.  We're talking about VirtualBox, right? Every
time I create a new virtual machine it automatically has a virtual CD/DVD
player on which I can mount ISO files.  Just tell vbox which ISO image you
want mounted on the virtual CD player and start the vm.

Are you seeing something very different at your end?

Yes. I've created just one VM (this is on my KDE-4 test system). On the 
Details tab I get a list of configuration variables with their values. 
Under CD/DVD ROM I have "Mount CD/DVD drive" selected, and the "Host CD/DVD 
drive" drop-down box contains just the one entry: /dev/fd0.

That's why I said I can't install a guest OS - the VM can't read the 
installation CD. Have I to make an ISO from the CD and mount that? Seems 
like a bit of a roundabout route if so.

I'm attaching a screen capture of the dialog window I see when mounting an
ISO file on the vm's virtual CD player.  If you are seeing something very
different, then that's where we need to start debugging.

I hope this group doesn't object to binary attachments -- it's fairly small.

Ah! Are you telling me I have to install the additions before /dev/hdc 
becomes visible? (That would also be one of my physical drives.) I had 
assumed they were for addition to an installed guest OS.

No, that's the iso I just happened to have attached to that vm -- it has
no effect on the host.  But my CD player does show up in the dialog box,
so I have no idea why yours doesn't.

In addition to the screenshot, using Linux it's very easy to create an ISO-file 
from an existing CD/DVD.
I always do it with:
# cp /dev/cdrom <path-to>/bladiebla.iso
(change paths / names as appropriate)

No need to install additional software to do this and I have succesfully used 
this to create ISO images from MS Windows install media as well for use with 
both VirtualBox and VMWare.

This is indeed strange - to make an ISO of a CD-ROM and install from that. 
I'll try it and see what happens. Thanks to you and Walt.

This is an easy way to install software that, when unpacked, is larger then a 
DVD, but don't want to copy it to the local drive every time.
I have a few ISO-images of around 14Gig with software on it. Just connect that 
to the virtual machine and install from there. :)
