Another user getting Block Device Mapping Invalid
Project->Compute->Instances
Launch Instance
Instance Name: MyCentos7 Availability Zone: nova Count:1
Select Boot Source: Image
Volume Size: 20GB
I hit the up-arrow on a previously uploaded Ubuntu14.04.5LTS
m1.small (2GB, 20GB)
Defaults on everything from that point hence
Launch Instance
I get the same useless error everyone else does: "Error: Failed to perform requested operation on instance "MyCentos7", the instance has an error status: Please try again later [Error: Build of instance e17bc224-42e2-49ec-9eb4-47cfe40d1cc3 aborted: Block Device Mapping is Invalid.]."
"Please try again later", ummmmm, what?
Anyway, the error is useless. I have sifted through tons of posts, lots of BS. If anyone has a straight answer they'd like to share, or a legitimate course of action on how to proceed, I'd appreciate it.
The error indicates that the cloud is not correctly configured. Try this: The instance launch dialog features a flag named something like "create volume", which is set to YES in the more recent versions Newton and Ocata. Set it to NO so that the instance uses ephemeral storage.
