Known Issues
| Issue | Description |
|---|---|
| Windows AMI launch times | Windows AMIs take longer to launch than Linux/UNIX instances due to larger AMI sizes and multiple reboots. |
| Windows AMI sizes | Windows AMIs are large and can easily reach the 10 GB limit. Before rebundling, check the size of the C:\ volume. |
| Amazon DevPay and Windows instances | Amazon DevPay does not yet support Windows paid or supported AMIs. This means that you currently can’t create a Windows AMI and sell it through DevPay, or associate an Amazon DevPay product code with a Windows AMI. |
| Windows instance availability | Initially, Windows instances will only be available in a single availability zone. Until notified, do not specify an availability zone when using ec2-run-instances; Amazon EC2 automatically launches Windows instances in the correct zone. |
| Limitation on drive mapping | There is currently no support for volume attachment to devices beyond /dev/sdp on instances running Linux/UNIX and xvdp on instances running Windows. |
| Limitation of AuthorizeSecurityGroupIngress | AuthorizeSecurityGroupIngress does not allow port ranges for group grants when using the command-line tools or the Query API. This is only supported through the SOAP API. |
| Instance limit | New users are limited to a maximum of 20 concurrent instances, but many of our customers use hundreds or thousands of instances. If you need a higher limit, go to http://www.amazon.com/gp/html-forms-controller/ec2-request. |
