Anonymous users2024-02-04After you use Fuel to automatically install the OpenStack-VC environment and create a VM, you will see Create-Configuration-Register-Delete in the VC taskbar, and then the dashboard prompts that no host can be found.
After I extended the instruction interval parameter, after rebuilding, I turned on the VM after registering the VM in the VC, and then the VC failed to delete the VMDK, the VM can be used normally, the configuration and UUID are the same as in the dashboard, and the BR100 is automatically created in the VC.

Anonymous users2024-02-03Metadata is literally metadata and is a concept that is not easy to understand.
It is also common to encounter it in other occasions besides OpenStack.
Metadata in OpenStack provides a mechanism for users to set the parameters of each instance.
For example, you want to set a property to the instance, such as the hostname.
An important application of metadata is to set the SSH public key for each instance.
There are two ways to set the public key:
1. When creating an instance, the leakage is injected into the file image.
2. After the information and dynamic instance is initiated, it is obtained through metadata and then written by script.
The second method is more flexible and can inject a public key to a non-root user.
