Hi all, I am trying to start an MPI Cluster in Amazon EC2. I am using the link "Start MPI Cluster" in the guide Bioconductor - Cloud AMI<http: bioconductor.org="" help="" bioconductor-cloud-ami=""/>. I try to launch the cluster with the instance type "cc2.8xlarge" but unfortunately I run into an error. It starts to create the stack but when it comes to the creation of the MasterInstance, I receive the status "CREATE_FAILED" with the reason Virtualization type 'hvm' is required for instances of type 'cc2.8xlarge'. I hope someone out there are able to help me and I would be very grateful to any help. Thank you in advance. Best regards, Jonas Gylden [[alternative HTML version deleted]]

The current Bioconductor AMIs are not HVM-based. However, the link above describes how you can create your own HVM AMI from an instance of the current AMI (running on a smaller instance type).

The Amazon Cluster Compute systems require ami images based on HVM virtualization. The images that work with the compute cluster systems don't work with the other types of systems (and vice versa) as far as I'm aware. -Mike -- Michael Steeves (steeves at raingods.net)
