No valid host was found - Instance created with ERROR status

When instance is created with Error status is it occupying compute resources? Suppose i have instance initiated with config 4vcpu and 16GB ram and it failed with ERROR status ???

If the error is "no valid host was found", the instance doesn't use resources on a compute host. Perhaps there are other error conditions where some disk space is occupied, but I can't confirm that and doubt it very much.

Did you check flavor resources and minimum requirements? For example if your flavor have 1 GB disk and your image needs more than 1GB this error appears.

I had same problem. That's correct if your flavor doesn't have enough resources for selected Image, you can't create VM and this error happens.

well I know there are many reasons to this but if instance is not completely created and their is no "IMAGE issue" answering first few guys...(and btw thanks for letting know this issue comes in such case as well).

I am curious if instance is not created and it may be due to any reason does it ....
