Boot Ubuntu 15 over http - wayne.workman2012 - 2015-11-06 02:03

Hello,

I've been browsing around here for a few hours now and have only found one relevant thread that talks about using httpd to load a linux live iso.

At home, I have a Fedora 21 server in the basement, it's setup as a FOG server. I have the Ubuntu 15 x64 iso mounted as read-only in the web-root here: /var/www/html/ubuntu

when I use a web browser to browse to x.x.x.x/ubuntu I can see the contents of the iso.

for my ipxe menu entry, this is what I have so far but it's not working out...

Code:

:ubuntu

kernel ${boot_url}/ubuntu/casper/vmlinuz.efi

initrd ${boot_url}/ubuntu/casper/initrd.lz

imgargs vmlinuz root=${boot_url}/ubuntu boot=casper netboot=http

boot

The computer I've been trying to boot using this method has 3 gigs of ram and is a dual core.

With Google, I couldn't find a good list of parameters with examples. For instance, I simply guessed to use netboot=http but I'm not sure if this is right or not.

It appears that the kernel and init are pulled and loaded, and then I simply get a PXE-M0F error, it looks like it's tftp related.

What's going wrong here? Any help would be appreciated.

I'm not aware of Ubuntu including any support for mounting the root filesystem via HTTP. You can export the root filesystem via NFS and boot using something like:

Code:

kernel ${boot_url}/ubuntu/casper/vmlinuz.efi initrd=initrd.lz \

       boot=casper netboot=nfs nfsroot=${nfs_root}/ubuntu

initrd ${boot_url}/initrd.lz

boot
