I've been playing with boot from volume for a bit. You can use it from the 'euca-run-instances', use the '-b, --block-device-mapping' option to specify the volume (or snapshot) e.g.<br>#euca-run-instances -b /dev/sda=vol-0000000f -b /dev/sdb=vol-0000000c ami-00000015 -t m1.tiny --kernel aki-00000014 --ramdisk ari-00000013<br>
<br>I recently added the functionality in novaclient to boot from volume (or snapshot) using the OS API. The changes are still pending review. But you can pull from my public repository to get the changes:<br><a href="https://github.com/rackspace/python-novaclient/">https://github.com/rackspace/python-novaclient/</a><br>
<br>The usage is:<br>root@server9-clone:~/openstack/creds/novaadmin# nova boot ---help<br>usage: nova boot [--flavor <flavor>] [--image <image>] [--meta <key=value>]<br> [--file <dst-path=src-path>] [--key_path [<key_path>]]<br>
[--key_name <key_name>] [--user_data <user-data>]<br> [--availability_zone <availability-zone>]<br> [--security_groups <security_groups>]<br> [--block_device_mapping <dev_name=mapping>]<br>
<name><br>
<br>The format of mapping is:<br>
<dev_name=<id>:<type>:<size(GB)>:<delete_on_terminate><br>
<br>e..g<br>nova boot --flavor 1 --image 50 --block_device_mapping /dev/vda=10:snap:10:True<br><br>Hope it helps!<br><br><div class="gmail_quote">On Thu, Nov 3, 2011 at 2:00 PM, Vishvananda Ishaya <span dir="ltr"><<a href="mailto:vishvananda@gmail.com">vishvananda@gmail.com</a>></span> wrote:<br>
