Cloud Bursting Amazon EC2

Community Support

Hi,

I have 2 KVM node running and one EC2 connected.
OpenNebula can monitor wild VM on EC2.

While I try to launch a instance from OpenNebula to EC2, it stays pending forever.
Can you show me some light where to debug? Thanks.

Below is template file
I am trying to launch ami-7ea24a17, which equals to public CentOS image on Amazon.

CONTEXT = [
NETWORK = “YES”,
SSH_PUBLIC_KEY = “$USER[SSH_PUBLIC_KEY]” ]
CPU = "0.1"
DISK = [
IMAGE_ID = “0” ]
GRAPHICS = [
LISTEN = “0.0.0.0”,
TYPE = “vnc” ]
LOGO = "images/logos/linux.png"
MEMORY = "128"
PUBLIC_CLOUD = [
AMI = “ami-7ea24a17”,
INSTANCETYPE = “t2.micro”,
KEYPAIR = “gsg-keypair”,
TYPE = “EC2” ]
SCHED_REQUIREMENTS = “PUBLIC_CLOUD = YES”
