Maximilian Güntner 66aa0743f0 vmm: allow net devices without ip and mask This change enables easier integration with third-party tools by removing the requirement for a dummy IP address when configuring tap devices. The modification applies to both CLI and API interactions. Previously, cloud-hypervisor would automatically set a default static IP address (192.168.249.1) if none was provided. This could lead to: * multiple devices without explicit IP configurations would end up with the same default IP * unnecessary inclusion of this IP in firewall rules * the IP address could clash with host networking and routing This introduces a new constraint: When providing an IP, the mask must also be provided. Removes warnings introduced in #7179. Closes issue #7083. Signed-off-by: Maximilian Güntner <code@mguentner.de>	2025-09-22 14:12:47 +00:00

Maximilian Güntner 66aa0743f0 vmm: allow net devices without ip and mask

This change enables easier integration with third-party
tools by removing the requirement for a dummy IP address
when configuring tap devices. The modification applies to
both CLI and API interactions.

Previously, cloud-hypervisor would automatically set a
default static IP address (192.168.249.1) if none was provided.

This could lead to:

* multiple devices without explicit IP configurations
  would end up with the same default IP
* unnecessary inclusion of this IP in firewall rules
* the IP address could clash with host networking and
  routing

This introduces a new constraint:
When providing an IP, the mask must also be provided.

Removes warnings introduced in #7179.
Closes issue #7083.
