Haha - and now i decide to RTFM:

I quote: "Please note that in order to reduce the size of JeOS to a
minimum SCSI drivers have not been included in the JeOS kernel. Please
make sure that you instruct VMWare to use an IDE drive instead."

Guess that's my problem!!!

Thanks for all your input. As far i understand it: jeOS is a lightweight
distro that does not include any unnecessary software, drivers and
kernel modules that are normally included for compatibility. I.E. They
do not need to include compatibility for 1000s of NIC cards, because all
it needs is the PCNet driver the VMWare emulates.

In reply to Tom: ive tried on 7.10, 7.04, and 6.06.1. VMWare-server
version 1.0.2 and 1.0.4. I think that is a fair spread to try on. 1
Thing that you said that stands out is that you used IDE. i always use
SCSI but i think its worth a try... thanks.

I've just installed JeOS 7.10 on VMware Workstation 6.0.2 on an Ubuntu 
7.10 i386 host. It installed perfectly using an IDE emulated hard disk 
and now it's updated. One cool thing I noticed is that the VMware guest 
kernel modules are included already in JeOS, that is vmhgfs, vmblock, 
vmxnet and vmmemctl.

I used to have a problem installing Dapper Server 6.06 on older versions 
of VMware. The solution I found was to use the desktop kernel rather 
than the server kernel as I couldn't get the server kernel to boot on 
virtual hardware. It's been ages since I had this problem though, I 
doubt it's even the same issue. What version of VMware software are you 
running?

Tom

Tht makes more sense, yes :)


I don't actually understand this at all...

I, like you, thought that JeOS would be the base operating system and 
then you'd install VMWare on that and then the Operating System on top 
of that, hence cutting out the overhead of a large bloated core 
operating system.


I think I'm missing something, but if anybody could explain the 
rationale behind running JeOS in a virtual machine I'd be grateful...


Sean


When you're building a distributable virtual appliance you want your OS 
to be start as small as possible. If you use Ubuntu Server you've got a 
lot more unnecessary bloat to cut down on. Virtual machines tend to run 
specific tasks, rather than be multi-function servers. Resources in a VM 
are also more precious than on a host OS because they are rationed by 
the host software.

Tom

Are you entirely sure chaps?

I thought JeOS was a bare-bones operating system designed for people
to base virtual appliances on.

In that case it would run on something like VMWare.

I noticed that, I thought I was just being dumb, until you mentioned it
Al... jeOS is the lightweight host OS..

You installed a system designed for running virtual machines _inside_ a 
virtual machine (VMWare)?

As I understand it jeOS is designed to be run on the bare metal in which you 
then create your virtual machines. jeOS isn't meant to be run inside virtual 
machine software.

Al.

[ubuntu-uk] jeOS!! umm does it work?

[Michael Holloway]

Has anybody else tried jeOS yet? 

I have tried it on 3 different VMWare servers, 2 AMD based, and one
Intel. No matter how hard i try, i cant get it to work. It installs
fine, and then freezes on boot, failing to load the Kernel. It would
appear that it cant mount the drive. Even when i edit the grub
parameters to use /dev/sda1 instead of the UUID. Even after booting from
the CD and reinstalling grub etc etc. I've tried to use SCSI and IDE
hard drives (i mean virtual hard drives) to no avail. Any one got any
ideas, or come across the problem?  Googling has not resulted in
anything useful.

btw , these 3 vmware servers are all running various other versions of
Ubuntu, from 6.06 to 7.10.
