Booting Ubuntu-14.04 cloud images without a cloud
Leave a reply
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:
wget cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-amd64-disk1.img
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 … Read the rest
