Subject: [alpine-devel] Notes on Alpine 2.4.2 in Amazon EC2

Just some notes on trying to get Alpine Linux running on an EC2 instance.

As of 27 May 2012, The Amazon Linux AMI includes pv-grub, so trying an 
alternate kernel is fairly simple:

* Start the instance (its some variant of redhat)
* wget the alpine iso and copy the /boot and /apk directories to the EC2 
  instance /
* create a apkovl.tar.gz that includes the ssh public keys, starts 
openssh, etc.; place the apkovl in /


The /boot/grub/grub.conf looks like this:

default=0
fallback=1
timeout=3
hiddenmenu

title Alpine Linux
root (hd0)
kernel /boot/grsec alpine_dev=xvda1:ext4 
modules=loop,squashfs,sd-mod,ext4 console=hvc0
initrd /boot/grsec.gz


title Amazon Linux AMI (PV)
root (hd0)
kernel /boot/vmlinuz-3.2.12-3.2.4.amzn1.i686 root=LABEL=/ console=hvc0
initrd /boot/initramfs-3.2.12-3.2.4.amzn1.i686.img

What doesn't work:


* Booting the 32bit kernel reports:
   ERROR: Invalid kernel: 'elf_xen_note_check: ERROR: Will only load 
images built for the generic loader or Linux images
   xc_dom_oparse_image returned -I


http://wiki.alpinelinux.org/wiki/Talk:Create_Alpine_Linux_PV_DomU says 
that's because the kernel uses PVOps and its running on 64 bit hardware.



* Booting the 64bit kernel reports:
   can only boot x86 32 PAE kernels, not xen-3.0-x86_64
   Error 13: Invalid or unsupported executable format
