Having trouble booting live image



  • I’m using Fog 1.2.0 with IPXE

    The iso I’m trying to load is a customized lubuntu image which boots and works just fine as a live image on some local host computer as well as in a virtual box. I have mounted the .iso file in the [url]http://${fog-ip}/fog/lublive/trusty[/url] directory using the command:
    [INDENT=1]mount -o loop lublive1.iso trusty/[/INDENT]

    Configuration 1:

    :lublive1
    initrd [url]http://${fog-ip}/fog/lublive/lublive1.iso[/url]
    chain memdisk iso raw ||
    goto MENU

    The iso image appears to download, the lubuntu splash screen appears with the loading bar, then it shows the following:

    [INDENT=1]command line: iso raw[/INDENT]
    [INDENT=1]MEMDISK: Image seems to have fractional end cylinder[/INDENT]
    [INDENT=1]MEMDISK: Image appears to be truncated[/INDENT]
    [INDENT=1]Disk is hd96, 149248 K, C/H/S = 65535/255/15 (El Torito/El Torito), EDD on, rw[/INDENT]
    [INDENT=1]Using raw access to high memory[/INDENT]
    [INDENT=1]Code 1844, meminfo 324, cmdline 8, stack 512[/INDENT]
    [INDENT=1]Total size needed = 2688 bytes, allocating 3k[/INDENT]
    [INDENT=1]Old dos memory at 0x92c00 (map says 0x9f000), loading at 0x92000[/INDENT]
    [INDENT=1]1588: 0xffff 15E801: 0x3c00 0xba6c[/INDENT]
    [INDENT=1]INT 13 08: Success, count = 1, BPT = 0000:0000[/INDENT]

    [INDENT=1]new: int13 = 9200000a int15 = 920003ef int1e = f000efc7[/INDENT]
    [INDENT=1]Loading boot sector… booting…[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]BusyBox v1.21.1 (Ubuntu 1: 1.21.0-1ubuntu1) built-in shell (ash)[/INDENT]
    [INDENT=1]Enter ‘help’ for a list of built-in commands.[/INDENT]
    [INDENT=1] [/INDENT]
    INDENT=1 Unable to find a medium containing a live file system[/INDENT]
    [INDENT=1] [/INDENT]
    Configuration 2:

    :lublive2
    kernel [url]http://${fog-ip}/fog/lublive/trusty/casper/vmlinuz[/url] boot=casper netboot=nfs
    nfsroot=[url]http://${fog-ip}/fog/lublive/trusty[/url]
    initrd [url]http://${fog-ip}/fog/lublive/trusty/casper/initrd.lz[/url]
    boot || goto MENU
    autoboot

    The pxe boot fails immediately and boots from the harddrive

    Configuration 3:

    :lublive3
    imgfetch [url]http://${fog-ip}/fog/lublive/lublive1.iso[/url]
    boot memdisk iso raw ||
    goto MENU

    Once again the iso image loads, the splash screen appears, but the result/error is the same as Configuration 1.

    Configuration 4:

    :lublive4
    kernel [url]http://${fog-ip}/fog/lublive/trusty/casper/vmlinuz[/url]
    initrd [url]http://${fog-ip}/fog/lublive/trusty/casper/initrd.lz[/url]
    imgargs vmlinuz boot=live config console=ttyS0 fetch=[url]http://${fog-ip}/fog/lublive/trusty/casper/filesystem.squashfs[/url]
    boot

    it appears to load vmlinuz and initrd but then the screen becomes blank and is unresponsive, I let it sit for a while in case it was loading the image and just taking a while but nothing happened.

    I also tried booting the unaltered standard lubuntu image and although it didn’t show the initial Memdisk errors as before, it still loaded a BusyBox shell and said “Unable ot find a medium containing a live file system”

    Any help or insight would be much appreciated.

    the “boot memdisk iso raw” method won’t work with linux disks, typically
    on the other one’s, you might be able to get some hints from this page [url]https://gist.github.com/robinsmidsrod/2234639[/url]
