Image too large for a given flavor
I have started up a test OpenStack envionment using 3 virtual machines for the controller, network, and compute nodes. Everything is working great and I am able to launch the CirrOS image as well as some of the Ubuntu Server images.
I have a custom CentOS image that I would like to launch, but the image is quite large, roughly 1.1GB. I have created a new flavor through the Horizon dashboard giving as many resources as my computer will possibly allow for me to try to boot this image, but when I try to launch the instance with this image, I get the following error:
Error: Failed to launch instance "Tools": Please try again later [Error: Build of instance 634c0e7b-4e82-4370-9e01-a19917e3a1ed aborted: Flavor's disk is too small for requested image.].
The CentOS image is 1.1GB but the flavor I'm using is:
vCPU:2 - RAM:2048MB - Root Disk:5GB
I understand that the image is a little larger but I believe these specs should be enough to run it, as I've done so in other environments with similar specs. Does anyone know what could be causing this error or what I can adjust to make the flavor large enough?
Is there anywhere I can find more specifics on what exactly was not large enough in the flavor?
