Many thanks again for your help.

@nsherin I’m sorry its taking me so long to answer but I’m checking on something. So please stick with me for a minute.

Also can you tell me what version of FOG (specifically) you are using?

george1421

This menu item is from my working production server

:os.Ubuntu.Desktop.17.10
kernel nfs://${fog-ip}:/images/os/ubuntu/Desk17.10/casper/vmlinuz.efi
initrd nfs://${fog-ip}:/images/os/ubuntu/Desk17.10/casper/initrd.lz
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/images/os/ubuntu/Desk17.10/ locale=en_US.UTF-8 keyboard-configuration/layoutcode=us quiet splash ip=dhcp rw
boot || goto MENU

Here is from your ipxe menu

:fog.ubuntu-mate
kernel tftp://t-pxe/os/ubuntu/16.04/mate/vmlinuz.efi
initrd tftp://t-pxe/os/ubuntu/16.04/mate/initrd.lz
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=t-pxe:/var/www/fog/dist/ubuntu/16.04/mate/ locale=en_US.UTF-8 keyboard-configuration/layoutcode=us quiet splash ip=dhcp rw
param sysuuid ${uuid}

I did notice that your menu is missing the boot instruction

boot || goto MENU

I did also notice an out of place sysuuid parameter, but I think FOG is doing that. That extra parameter is not hurting your boot process, I think the missing boot command is.

Thanks for your help. I’m running version 1.5.2

My /etc/exports file:

/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1

george1421

@nsherin Those settings are correct. What I’m pointing out is wrong is this parameter: netboot=nfs nfsroot=t-pxe:/var/www/fog/dist/ubuntu/16.04/mate/

The FOG server is only sharing out /images/… yet you are telling the client to get its files from /var/www/fog/dist… That isn’t going to work. Plus the /var/www/… path is the base directory for the web server.

My instructions that I posted show you expanding the ubuntu iso image to /images/os/ubuntu/… which IS in the nfs export path.

With iPXE you can use any of several protocols to get to your files.
if you use
tftp:// the base path is /tftpboot
http:// the base path is /var/www/html
nfs:// the base path is /images

The issue is the kernel it self has to reach out to this path you defined
nfsroot=t-pxe:/var/www/fog/dist/ubuntu/16.04/mate/
Yet it can’t get there because /var/www is not exported from the FOG server only /images and /images/dev is.

Look at my menu item I posted below, you can see the nfs:// is used for ipxe to deliver the files as well as the nfsroot path for ubuntu’s kernel.

@george1421 said in Booting Ubuntu Live CD:

I’ve got a bit further - I’ve added

boot || goto MENU

I now get a message ‘Unable to find a live file system on the network’:

0_1523992151904_Ubuntu 64-bit-2018-04-17-20-08-52.png

Also, do you know the parameters I’d need in locale= and keyboard-configuration/layoutcode for a UK keyboard?

Many thanks.

george1421

@nsherin The problem you now see is exactly what I described below. Fix your nfsroot path and file locations.

I would say the local for your side of the pond would be en_GB.UTF-8

@george1421

Thanks for that - I’ve moved the files from the DVD into /images/os/ubuntu/16.04/mate and modified the parameters to read:

kernel nfs://t-pxe/images/os/ubuntu/16.04/mate/casper/vmlinuz.efi
initrd nfs://t-pxe/images/os/ubuntu/16.04/mate/casper/initrd.lz
imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=t-pxe:/images/os/ubuntu/16.04/mate/ locale=en_US.UTF-8 keyboard-configuration/layoutcode=us quiet splash ip=dhcp rw
boot || goto MENU

It’s still complaining about the lack of a file system on the network.

@nsherin said in Booting Ubuntu Live CD:
ok next change (understand I’m swagging it a little)

Possibly it doesn’t like the dns names here of t-pxe. Replace the t-pxe value with the iPXE menu variable of ${fog-ip} That will then set the ip address of the fog server in there instead of the dns names. Refer to my working menu. on how to place the ipxe variable.

nsherin

Thanks! That worked! I replaced t-pxe with the server’s IP 192.168.0.22 and I now have a booted live CD!

nsherin

Oh and for a UK keyboard, the syntax is:

locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb

george1421

@nsherin Issue solved then?

@george1421

Almost - I’m just trying Ubuntu Server now and have added another menu option:

Menu Item: fog.ubuntu-server
Description: Ubuntu Server 16.04
Parameters:
kernel nfs://192.168.0.22/images/os/ubuntu/16.04/server/install/vmlinuz
initrd nfs://192.168.0.22/images/os/ubuntu/16.04/server/install/initrd.gz
imgargs vmlinuz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.22:/images/os/ubuntu/16.04/server/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash ip=dhcp rw
boot || goto MENU

I have copied the Ubuntu Server CD contents into /images/os/ubuntu/16.04/server/

It boots to the Ubuntu installer and then asks me to insert a CD-ROM.

Any ideas would be great. Thanks!

george1421

@nsherin Again please review this post (especially Note1 where the installer asks for the cdrom during installation. And then note2 where it says where to get what you need): https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/6

@george1421

Thanks for that - I’ve got it booting - my menu entry now looks like:

Menu Item: fog.ubuntu-server
Description: Ubuntu Server 16.04
kernel tftp://192.168.0.22/os/ubuntu/16.04/server/vmlinuz
initrd tftp://192.168.0.22/os/ubuntu/16.04/server/initrd.gz
imgargs vmlinuz initrd=initrd.gz root=/dev/nfs netboot=nfs nfsroot=192.168.0.22:/images/os/ubuntu/16.04/server/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb
boot || goto MENU

Many thanks again for your help!
