Openstack / Create New Flavor
Create New Flavor
Creates a new OpenStack flavor for compute instances.
openstack flavor create <flavor_name> --vcpus 2 --ram 4096 --disk 20 openstack flavor create <flavor_name> --vcpus 2 --ram 4096 --disk 20 #!/bin/bash
# Create New Flavor
openstack flavor create {{flavor_name}} --vcpus 2 --ram 4096 --disk 20 import subprocess
# Create New Flavor
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"openstack",
"flavor",
"create",

"--vcpus",

"20"
]
try:

run_command() When To Use
During the setup of a new environment requiring specific compute resources.
Pro Tip
Check quotas before creation to avoid exceeding limits set by the OpenStack administrator.
Command Builder
Tune the command before you copy it
openstack flavor create <flavor_name> --vcpus 2 --ram 4096 --disk 20 Anatomy of Output
Understanding the result
+---------------------------------------------+ Table Header Separator Indicates the start of the newly created flavor information.
| ID | Flavor ID Unique identifier assigned to the newly created flavor.
| vCPUs: 2 | Flavor Specifications Number of virtual CPUs allocated to this flavor.
Troubleshooting
Common pitfalls
Quota exceeded for instance flavors
Solution: Reduce the number of existing flavors or request an increase from the administrator.
Invalid value for RAM: must be greater than 0
Solution: Ensure that RAM is set to a valid positive integer.
Failed to create flavor: Invalid disk size
Solution: Ensure the disk size is a valid integer greater than or equal to the minimum required.
