<![CDATA[Trying to build my first bzImage or custom kernel]]>So, I’d say to some degree that i know enough Linux to be dangerous, but i might be selling myself short. Anyway, I’ve got my first Fog env up and running and have completed a number of imaging tasks. The need has come up for me to become able to add drivers to the kernel image that’s passed onto clients booting PXE.

I’ve followed instructions here:
[url]http://fogproject.org/wiki/index.php?title=Building_a_Custom_Kernel[/url]
and [url]http://dinomite.net/blog/2007/setting-up-ubuntu-for-building-kernel-modules/#.T48antUcuo5[/url]

The only item I added in the GUI (from make xconfig) was “VMware PVSCSI driver suport” I then saved and closed that guy then ran the make bzImage. the product of that was, after some time:

drivers/net/dl2k.c: In function ‘rio_ioctl’:
drivers/net/dl2k.c:1294: error: implicit declaration of function ‘capable’
drivers/net/dl2k.c:1294: error: ‘CAP_NET_ADMIN’ undeclared (first use in this function)
drivers/net/dl2k.c:1294: error: (Each undeclared identifier is reported only once
drivers/net/dl2k.c:1294: error: for each function it appears in.)

make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2
root@AusFog01:/usr/src/linux-source-2.6.32#

This is what i have for my fog server and where this failure occured:
root@AusFog01:/usr/src/linux-source-2.6.32# uname -a
Linux AusFog01 2.6.32-45-server #101-Ubuntu SMP Mon Dec 3 15:54:27 UTC 2012 x86_64 GNU/Linux

And I’m running fog .32

I’m able to boot the fog image and blast images to the VM. Be it paravirtual or LSI Logic SAS. Havent tested the other modes yet tho.

At least you got it sorted out now? Were you able to test booting to the SCSI VMware hard drive?

This was the reason for my last two failures with init and CPU arch:

The kernel compiled and the bzImage was produced but it wont boot. i get this on the VM:
“kernel panic - not syncing: No init found. Try passing init= option to kernel”

And a thin client also fails with “This kernel requires x86_64 CPU, but only detected an i686 CPU”

So, it looks like I have more things to do in xconfig. Back to the console!

Which I realize is nothing like a solution… More just a curiosity, haha.

On another note, I had a similar problem to yours, so I updated the kernel to include those VMWare drivers. And then I ended up not needing it. The only VMs I need to connect to FOG are my reference images, so when I created the new VMs I created them as blank templates, deleted the default SCSI hard drive, and added VM IDE hard drives which FOG 0.32 picked up just fine.

Not sure if that helps you in your situation at all (especially if you’re trying to connect exisitng vms with SCSI based vmdks), but if you’re sick of banging your head against the bzImage errors and you have the option to switch, it works.

more info on my server:
minimalist/base/headless install of Ubuntu Server 11.10. Then installed fog .32 per instruction. then added other tidbits. and ultimately, through this process, added GDM and X.

I dont need that for my environment so i simply removed it and i think i got a bit further with the make bzImage job.

however, on to the next failure:

Still tracking this. Figured I’d post my findings in case I’m not alone.
