Why Can I Not Use m1.small And m1.medium Instances With By EBS Boot Image On Amazon AWS?

  • 772

I modified a Canonical ubuntu image on a t1.micro sized instance, saved the EBS boot image, and am now trying to re-start it using a slightly larger instance.

The only instances available (for regular and spot requests) are:

  • t1.micro
  • m1.large
  • etc...

Why can I not start an m1.small or m1.medium sized instance?

Micro instances are too weak, but a m1.large is too powerful...

    The t1.micro instance type supports both 32-bit and 64-bit AMIs.

    m1.small and c1.medium only support 32-bit AMis at this time.

    All the rest (larger) instance types only support 64-bit AMIs.

    You created a 64-bit AMI, so it will run on t1.micro and the larger instance types, but not on m1.small or c1.medium. You would need to create a 32-bit AMI to run on those types (including t1.micro which can run either).
