Amazon EC2: how to convert an existing PV AMI to HVM -



Amazon EC2: how to convert an existing PV AMI to HVM -

question:

how should utilize new aws ec2 classes (r3, i2) existing ami without recreating whole scheme setup?

the new ec2 classes back upwards hvm based virtualization have pvm ami images.

answer:

start ubuntu hvm linux, version, new

start ubuntu / existing ami / pvm linux, , install grub packages on them: apt-get install grub-pc grub-pc-bin grub-legacy-ec2 grub-gfxpayload-lists

stop pvm linux

detach root (/dev/sda1) partition @ pvm linux

attach pvm linux root partition running hvm linux somewhere, e.g.: /dev/sdf

on hvm linux: mkdir -p /mnt/xvdf && mount /dev/xvdf /mnt/xvdf

rsync -avzxa /boot/ /mnt/xvdf/boot/

mount -o bind /dev /mnt/xvdf/dev && mount -o bind /dev/pts /mnt/xvdf/dev/pts && mount -o bind /proc /mnt/xvdf/proc && mount -o bind /sys /mnt/xvdf/sys

chroot /mnt/xvdf

grub-install --no-floppy --recheck --force /dev/xvdf

update-grub2

exit chroot: ctrl+d

stop hvm linux

detach /dev/sda1 original root , detach /dev/sdf pvm root

attach pvm root hvm linux /dev/sda1

start hvm linux, voilà!

create new ami image running hvm linux, hvm virtualized.
