Server configuration file

Eucalyptus and Amazon EC2 supports 5 different types of Virtual Machines to instantiate. These differe from one-another by CPU, memory and disk characteristics. Eucalyptus allows the modification of these characteristics. The 5 VM types and their associated default characteristics inside Eucalyptus are:

1. m1.small: 1 VCPU, 128 MB RAM, 2 GB Disk
2. c1.medium: 1 VCPU, 256 MB RAM, 5 GB Disk
3. m1.large: 2 VCPU, 512 MB RAM, 10 GB Disk
4. m1.xlarge: 2 VCPU, 1024 MB RAM, 20 GB Disk
5. c1.xlarge: 4 VCPU, 2048 MB RAM, 20 GB Disk

Configuring the server part is done by using the following options:

• BATCHNAME: the name of the batch system to be used. This is recognized internally by the DIET Batch System and should always have the value eucalyptus.
• PATHTONFS: path to a temporary directory
• CLOUDURL: the URL of the Cloud System's management service
• EMINAME: the name of the Virtual Machine Image containing the service
• ERINAME: the name of the Ramdisk image to be used when instantiating the service
• EKINAME: the name of the Kernel image to be used when instantiating the service
• VMTYPE: the type of the Virtual Machine to be instantiated
• KEYNAME: the name of the keypair created for use in the Cloud System
• VMMINCOUNT: minimum number of VM instances that is acceptable for the current service call to succede
• VMMAXCOUNT: maximum number of VM instances for the current service call
• PATHTOCERT: path to the X.509 certificate given by the Cloud System
• PATHTOPK: path to the private key that the current Cloud user has associated to the Cloud System

An example of a valid configuration is the following:
