Public bug reported:
Description
===========
Openstackclient + Nova API accept to rebuild server with virtual size greater
than the specified flavor’s disk size.
Steps to Reproduce
==================
1 - Create a server specifying a flavor with small disk size (example: 1 GB)
and an image small enough to fit.
openstack flavor create --ram 512 --disk 1 --vcpus 1 tiny
openstack server create –flavor tiny –image cirros vm-test
2 - Try to rebuild the server using a larger image but that still fits. It’s
virtual size must be greater than the flavor’s disk size.
openstack server rebuild –image ubuntu-jammy vm-test
Expected Behavior
=================
The rebuild process should fail and the created VM must retain the previous
image.
Actual Result
=============
The rebuild process starts, going to the REBUILDING state. After that, the
process fails, the VM state changes to ERROR and a FlavorDiskSmallerThanImage
Exception is thrown by Nova.
Environment
===========

Title:
VM rebuild starts even if image virtual size is greater than the
flavor's disk size
Status in OpenStack Compute (nova):
New
Bug description:
Description
===========
Openstackclient + Nova API accept to rebuild server with virtual size greater
than the specified flavor’s disk size.
Steps to Reproduce
==================
1 - Create a server specifying a flavor with small disk size (example: 1 GB)
and an image small enough to fit.
openstack flavor create --ram 512 --disk 1 --vcpus 1 tiny
openstack server create –flavor tiny –image cirros vm-test
2 - Try to rebuild the server using a larger image but that still fits. It’s
virtual size must be greater than the flavor’s disk size.
openstack server rebuild –image ubuntu-jammy vm-test
Expected Behavior
=================
The rebuild process should fail and the created VM must retain the previous
image.
Actual Result
=============
The rebuild process starts, going to the REBUILDING state. After that, the
process fails, the VM state changes to ERROR and a FlavorDiskSmallerThanImage
Exception is thrown by Nova.
Environment
===========
