Thanks again for your reply. Still no joy.

I’ve recopied the contents of the 18.04.1 LTS iso to /images/os/ubuntu/18.04/mate. after cleaning out that directory.

My menu config is as follows:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/vmlinuz
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd imgargs vmlinuz initrd=initrd root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

There is no initrd.lz so had to change it to initrd

Booting up my test PXE client VM gives me a kernel panic:


I added the following to /etc/exports:

/images/os/ubuntu/18.04/mate *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

And rebooted the server. Same result!

I don’t want to use a DHCP assigned IP on my PXE server as I need it to resolve local DNS queries from my internal DNS server on the network. Is there a workaround/

Many thanks,
Neil

Thanks for your reply - I’ve been away for a few days, so have only just got back to working with this.

I’ve now put the following code in the menu:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/vmlinuz
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz
imgargs vmlinuz initrd=initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

But when booting, I get booted into maintenance mode. Pressing CTRL+D allows me to get a prompt. I can then run startx to bring up the GUI. However, starting the installer doesn’t work. Opening a terminal and typing ifconfig gives me an IP address but the machine won’t do any DNS lookups or ping to say google.com

Here’s the error I get on boot up:

I also tried using ‘linux’ from the netboot installer and initrd.lz with this combination:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/linux
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz
imgargs linux initrd=initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

Same result

Any help would be much appreciated.

Many thanks,
Neil

Thanks again for your reply. I get a bit further now, but end up being booted into emergency mode.

I’ve copied over initrd.gz from the netboot.tar.gz file and placed it into /images/os/ubuntu/18.04/mate/casper/linux

I’ve changed my menu entry to read:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/linux
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz
imgargs linux root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

If I use the ‘linux’ file from the netboot.tar.gz file, I get:

If I rename the vmlinuz file that is part of the Live CD ISO to linux in /images/os/ubuntu/18.04/mate/casper/, I get:

Thanks for your reply.

Still no luck I’m afraid - I downloaded netboot.tar.gz from http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/

I then extracted the tar file and from /ubuntu-installer/amd64, copied the file ‘linux’ to /images/os/ubuntu/18.04/mate/casper

I then edited my Fog menu entry as follows:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/linux
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz imgargs linux root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

The error is still the same one.

Any ideas would be great.

Many thanks,
Neil

Hi,

I’ve got my Fog/IPXE server up and running and can boot the Ubuntu Mini ISO without issues.

Just tried to set up booting an Ubuntu 18.04 Live CD.

I’ve copied it to /images/os/ubuntu/18.04/mate and created the following Fog menu entry:

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/vmlinuz
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz imgargs vmlinuz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

When my test VM tries to boot, I get an error Unable to mount root fs on unknown-block(0,0) - I’ve attached a screenshot.

My /etc/exports file shows this:

/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)

Any help would be much appreciated!

Many thanks,
Neik

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!

@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!

Oh and for a UK keyboard, the syntax is:

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

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

@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.

@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’:

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

Many thanks.

@george1421

Thanks for your help. I’m running version 1.5.2

My /etc/exports file:

/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1

Thanks - but that’s the guide I followed - which hasn’t worked. I’m not using http here.

TFTP seems to be working - otherwise surely I wouldn’t be getting ok for both vmlinuz.efi and initrd.lz in the screen grab in my original post.

In my boot options, I’m using NFS and I can connect to that NFS export/share just fine from another workstation. I am using the same parameters - modified for my setup as in the example in the URL.

Hi,

I’ve set up FOG using this guide here: https://github.com/marcbizal/FOG-Install-Guide

I’ve set up DNSMASQ in ProxyDHCP mode.

Booting a couple of ISOs - Acronis TrueImage 2016 and the Ubuntu Net installer CD work fine.

However, I’m trying to get the Ubuntu Live CD to boot. I’ve done the following:

in /tftpboot, created a path of /os/ubuntu/16.04/mate. So in /tftpboot/os/ubuntu/16.04/mate, I’ve then copied initrd.lz and vmlinuz.efi.

In /var/www/fog, I’ve created a dist folder for holding distributions. So for Ubuntu MATE, I’ve st up the following: /var/www/fog/dist/ubuntu/16.04/mate

I’ve copied the contents of the ISO to here.

I’ve also set up the NFS export to /var/www/fog/dist - this is accessible from another Linux machine.

I have also tested TFTP by retrieving vmlinuz.efi from /tftpboot/os/ubuntu/16.04/mate from another Linux machine.

I’ve set up a menu entry with the following details:

Menu Item: fog.ubuntu-mate
Description: Ubuntu 16.04 MATE
Parameters:
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

However, when my test VM boots via PXE and I choose the Ubuntu 16.04 MATE, I get the following:

Any help would be much appreciated!

Many thanks,
Neil
