Importing OpenSolaris EC2 Image on Local Xen Environment

In this blog entry, I am going to walk you through the steps for importing OpenSolaris Amazon EC2 AMI on local Xen environment running on OpenSolaris 2008.11.

I assume
– you are running OpenSolaris 2008.11 build rc2 dom0.
– ec2 ami/api tools installed at /opt/ec2
– your ec2 certificate and private key files available at /opt/ec2/keys
– your ec2 keypair file located at /opt/ec2

[ Step-1 ]
Launch fresh OpenSolaris 2008.11 AMI Instance

ec2-run-instances ami-7db75014 -k your-keypair

Login in with your keypair file

ssh -i /opt/ec2/your-keypair

[ Step-2 ]
Remove EC2 specific stuff from the instance.

Open “/etc/ssh/sshd_config” and replace “PermitRootLogin without-password” with “PermitRootLogin yes” and save the file.

Set the root password

passwd: Changing password for root
New Password:
Re-enter new Password:
passwd: password successfully changed for root

Disable and remove ec2 specific services

svcadm disable svc:/ec2/sshkey:default
svcadm disable svc:/ec2/fixes:default
svcadm disable svc:/ec2/mount:default

svccfg delete svc:/ec2/sshkey:default
svccfg delete svc:/ec2/fixes:default
svccfg delete svc:/ec2/mount:default

[ Step-3 ]
Log out of the ec2 instance and transfer your keys at /mnt/keys to begin re-bundling image.

scp -i /opt/ec2/id-your-keypair -r /opt/ec2/keys/

[ Step-4 ]
Login back to ec2 instance.

ssh -i /opt/ec2/your-keypair

[ Step-5 ]
Start bundling the image.

# cd /mnt
# /opt/ec2/sbin/ -v opensolaris_2008_11_ami.img
Creating image file /mnt/opensolaris_2008_11_ami.img
Preparing clone pool on /dev/lofi/1
# will take about 10-15 minutes to create raw opensolaris image.

[ Step-6 ]
Bundle image and create parts.

export BUCKET=my-bucket
export JAVA_HOME=/usr/jdk/latest
export EC2_HOME=/opt/ec2
export PATH=$PATH:$EC2_HOME/bin
export RUBYLIB=$EC2_HOME/lib
export EC2_URL=

export EC2_PRIVATE_KEY=/mnt/keys/pk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.pem
export EC2_CERT=/mnt/keys/cert-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.pem

export EC2_KEYID=xxxxxxxxxxxxxxxxxxxxxxx
export EC2_KEY=”xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”

export DIRECTORY=/mnt
export IMAGE=opensolaris_2008_11_ami.img

# ec2-bundle-image -c $EC2_CERT -k $EC2_PRIVATE_KEY \
–kernel aki-6552b60c –ramdisk ari-6452b60d \
–block-device-mapping “root=rpool/52@0,ami=0,ephemeral0=1” \
–user <user-id> –arch i386 \

[ Step-7 ]
Upload image parts on s3

# cd $DIRECTORY/parts

# ec2-upload-bundle -b $BUCKET -m opensolaris_2008_11_ami.img.manifest.xml \
–url \
–retry -a $EC2_KEYID -s $EC2_KEY

[ Step-8 ]
Log out of the instance.
Download image parts and unbundle it to re-create the raw image locally.

# mkdir /osol-ec2-image
# mkdir /osol-ec2-image/parts
# cd /osol-ec2-image/parts

# ec2-download-bundle -b my-bucket -m opensolaris_2008_11_ami.img.manifest.xml \
-a <your-access-key-id> -s <your-secret-key-id> \
–privatekey /opt/ec2/keys/pk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx .pem

# ec2-unbundle -m opensolaris_2008_11_ami.img.manifest.xml \
-k /opt/ec2/keys/pk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx .pem

# mv opensolaris_2008_11_ami.img
# cd /osol-ec2-image/

[ Step-9 ]
Create “” at /osol-ec2-image with following lines

name = “opensolaris-ec2-image” vcpus = 1 memory = “1024”disk = [‘file://osol-ec2-image/opensolaris_2008_11_ami.img,0,w’] 

vif = [”]

on_shutdown = “destroy”
on_reboot = “restart”
on_crash = “destroy”

[ Step-10 ]
Launch domu image and login with root user and the password you set during step-2

xm create

Using config file “./”.
Started domain opensolaris-ec2-image
xm console opensolaris-ec2-image
v3.1.4-xvm chgset ‘Mon Oct 13 22:14:51 2008 -0700 15904:94bd0a643efe’
