Fwd: unable to launch the instances using lifeguard
shlomo....@gmail.com
The lifeguard-dev group is the place for this question.
It's hard to guess what might be going wrong here. There is a bug in
PoolManager.java at line 399
http://code.google.com/p/lifeguard/source/browse/trunk/java/com/directthought/lifeguard/PoolManager.java?r=83#399
where the Exception is caught but not printed, and this prevents the
actual problem from being reported.
If you're feeling brave you can change PoolManager.java's line 399 as follows:
Old:
logger.warn("Failed to launch instance(s). Will retry");
New:
logger.warn("Failed to launch instance(s). Will retry", ex);
and rebuild the library.
This will allow the actual underlying problem to be reported.

and regarding launching permissions
I am able to launch instances using Elastic Fox with the same credentials
regarding number of instances presently only 7 instances are running
in the account
Please let me know any other modifications to be done to make it work
Thanks and Best regards

The service AMI is an image that you should build yourself. On startup
it should automatically parse the UserData and start up the desired
service accordingly. You use the standard Amazon EC2 AMI Tools to
create an image and register it with EC2.
I have only built Linux AMIs, so I can't comment on how to build a
Windows AMI with the tools.

Hi Shlomo,
Please tell me how to create Windows AMI through life guard.
ultimately I need to create Windows AMI... The error I got is when I
tried to launch a windows AMI - ami-0529ce6c

You might find the following article, written by David Kavanagh (the
creator of lifeguard) helpful overall:
http://developer.amazonwebservices.com/connect/entry.jspa?externalID=915&categoryID=102
Lifeguard is not related to the boto library. The boto library can be
used to build a framework that works similarly to lifeguard.
