So, Ubuntu-14.04, Trusty Tahr, is out; and booting the cloud images requires a bit more hacking than booting the 12.04 cloud images. Here goes:
Get the image, resize and loop-back mount it:
qemu-img convert -c -O qcow2 trusty-server-cloudimg-amd64-disk1.img trusty-server-cloudimg-amd64-disk1_30GB.qcow2
qemu-img resize trusty-server-cloudimg-amd64-disk1_30GB.qcow2 30G
sudo modprobe nbd
sudo qemu-nbd -c /dev/nbd0 `pwd`/trusty-server-cloudimg-amd64-disk1_30GB.qcow2
ls image || mkdir image
sudo mount /dev/nbd0p1 image
Tell the system it’s not booting in a cloud:
sudo sed -ri 's|^(GRUB_CMDLINE_LINUX_DEFAULT=).*$|\1" ds=nocloud"|' image/etc/default/grub
sudo sed -ri 's|^#(GRUB_TERMINAL=console)$|\1|' image/etc/default/grub
sudo mkdir -p image/var/lib/cloud/seed/nocloud
sudo tee image/var/lib/cloud/seed/nocloud/meta-data <<EOF
instance-id: ubuntu
local-hostname: ubuntu
EOF
sudo tee image/var/lib/cloud/seed/nocloud/user-data <<EOF
#cloud-config
password: ubuntu
chpasswd: { expire: False }
ssh_pwauth: True
EOF
sudo sed -ri "s|^(127.0.0.1\s*localhost)$|\1\n127.0.0.1 `cat image/etc/hostname`|" image/etc/hosts
Unmount:
sudo umount image
sudo qemu-nbd -d /dev/nbd0
sudo modprobe -r nbd
Boot and customize (log in with username/password ubuntu/ubuntu):
Upload and run in a cloud.
