PXE booting / TFTP/DHCP issue (using Cobbler 2.0)

Question

I'm using Cobbler 2.x from the EPEL repositories. Have used 1.6 for ages.

I've imported the CentOS 5.5 DVD (also tried this with 5.4). The DVD imports with no apparent issue, and sets up the standard and xen kernel distros. If I build a system and provision it with the standard kernel it works perfectly.

However, if I build a system and provision it with the xen kernel, the process fails while trying to download the stage 1 kernel.

from syslog w/tftp -vvv logging enabled.

for this particular system my pxelinux.cfg is:

default linux
prompt 0
timeout 1
label linux
        kernel /images/centos5.5-xen-x86_64/vmlinuz
        ipappend 2
        append initrd=/images/centos5.5-xen-x86_64/initrd.img ksdevice=bootif lang=  kssendmac text  ks=http://192.168.180.10/cblr/svc/op/ks/system/sfo-virt-01

I've quintuple-checked the paths that are requested and everything exists and is available over the network. I've been beating my head over this for over a day and any insight would be incredibly appreciated. I've md5sum'd everything I can think of and am totally without ideas at this point.

Thanks.

Solution

Try transferring the files over tftp:

[random-box]$ tftp sfo-util-01
get /pxelinux.0
get /pxelinux.cfg/01-00-25-90-19-4c-21
get //images/centos5.5-xen-x86_64/vmlinuz

My guess from the looks of the retries in the log is that in the manual test you on't be able to get the vmlinuz file, due to the double slash.

Try:

kernel images/centos5.5-xen-x86_64/vmlinuz

And then test via manual tftp calls.

Did it ever work?
