Amazon Elastic Compute Cloud User Guide for Linux Instances Creating an AMI from an Instance Store-Backed Linux Instance Note that the console parameter is pointing to hvc0 instead of ttyS0 and that the xen_emul_unplug=unnecessary parameter is missing. Again, your options may differ. 6. Edit the /boot/grub/menu.lst file with your favorite text editor (such as vim or nano) to change the console and add the parameters you identified earlier to the boot entries. title Ubuntu 12.04.3 LTS, kernel 3.2.0-54-virtual root (hd0) kernel /boot/vmlinuz-3.2.0-54-virtual root=LABEL=cloudimg-rootfs ro console=ttyS0 xen_emul_unplug=unnecessary initrd /boot/initrd.img-3.2.0-54-virtual title Ubuntu 12.04.3 LTS, kernel 3.2.0-54-virtual (recovery mode) root (hd0) kernel /boot/vmlinuz-3.2.0-54-virtual root=LABEL=cloudimg-rootfs ro single console=ttyS0 xen_emul_unplug=unnecessary initrd /boot/initrd.img-3.2.0-54-virtual title root kernel 7.

(For Ubuntu 14.04 and later only) Starting with Ubuntu 14.04, instance store backed Ubuntu AMIs use a GPT partition table and a separate EFI partition mounted at /boot/efi. The ec2-bundle-vol command will not bundle this boot partition, so you need to comment out the /etc/fstab entry for the EFI partition as shown in the example below.

Upload your credentials to your instance. We use these credentials to ensure that only you and Amazon EC2 can access your AMI. a. Create a temporary directory on your instance for your credentials as follows: [ec2-user ~]$ mkdir /tmp/cert This enables you to exclude your credentials from the created image. 94
