3 (Optional) Enter a number in the Machine quota text box to set the maximum number of machines
that can be provisioned on this reservation.
Only machines that are powered on are counted towards the quota. Leave blank to make the
reservation unlimited.
4 Select a method of assigning key pairs to compute instances from the Key pair drop-down menu.
Option Description
Not Specified Controls key pair behavior at the blueprint level rather than the reservation level.
Auto-Generated per Business Group Every machine provisioned in the same business group has the same key pair,
including machines provisioned on other reservations when the machine has the
same compute resource and business group. Because key pairs generated this
way are associated with a business group, the key pairs are deleted when the
business group is deleted.
Auto-Generated per Machine Each machine has a unique key pair. This is the most secure method because no
key pairs are shared among machines.
Specific Key Pair Every machine provisioned on this reservation has the same key pair. Browse for
a key pair to use for this reservation.
5 If you selected Specific key Pair in the Key pair drop-down menu, select a key pair value from the
Specific key pair drop-down menu.
6 If you are configured for Amazon Virtual Private Cloud, enable the Assign to a subnet in a VPC
check mark box. Otherwise, leave the box unchecked.

load balancers options appear in a popup menu rather than on this same page.
For a VPC reservation, specify the security groups and subnets for each VPC that is allowed in the
reservation.

list.
Select each available location or subnet that you want to be available for provisioning.
8 Select one or more security groups that can be assigned to a machine during provisioning from the
Security groups list.
Select each security group that can be assigned to a machine during provisioning. Each available
region requires at least one specified security group.
9 Select one or more available load balancers from the Load balancers list.
If you are using the elastic load balancer feature, select one or more available load balancers that
apply to the selected locations or subnets.
