Hello, I have a question about cloud-init:
After installing vm, I installed cloud-init immediately, and enabled its
four services, and then I can use cloud-init in the admin interface.
However, I don't know how cloud-init knows where to get the relevant
information (such as host name, SSH secret key, etc.) that I configured on
the admin interface ? For I haven't configured the data source for
cloud-init.
Why it can works ?
Thanks!

Hi,
The relevant information comes as a payload to the VM, a CD-ROM
containing the data source.
Why it can works ?
Cloud-init detects the data source and configures the OS.
Please note that once the VM booted, the only way to provide the
cloud-init payload is by using Run-Once.
For a VM that didn't boot, a regular run will work as well.

Liran
Thanks!

Do you mean that you can use cloud-init for the first normal startup of a virtual machine
that has not yet been booted, and then you can't use cloud-init for subsequent normal
startup?
Is it possible to use cloud-init with the run-once boot option as long as the virtual
machine has already been started?

Yes. This is for safety from overriding a configuration on future boots.

Yes, if you set it in run-once
the payload will be included to the VM
on boot, regardless if it booted already or not.

Wouldn't the cloud-init information I configured in the initial run properties page of
the virtual machine be unnecessary?

In that case - correct. Only the
configuration you set in the run-once
will be taken into account when you run it.
