| Error | Solution |
|---|---|
| Failed to start VM | Check that the VM has sufficient resources (CPU, RAM, disk space) and that the virtualization extensions are enabled. |
| Timeout errors | Check the network connection and ensure that the VM is properly configured for networking. |
Deployment Guide with Repositories and Retention Policies
Configuring Repositories
Multipass allows you to configure repositories to manage VM images and templates:
- Create a new repository by running the command `multipass create-repo
`. - Add images to the repository by running the command `multipass add-image
`.
Configuring Retention Policies
Multipass allows you to configure retention policies to manage VM lifecycle:
- Create a new retention policy by running the command `multipass create-retention-policy
`. - Configure the retention policy by setting the `ttl` (time-to-live) and `max-snapshots` options.
Alternatives to Multipass
Other Virtualization Platforms
While Multipass is a powerful virtualization platform, there are other alternatives to consider:
- VirtualBox: A popular, open-source virtualization platform for x86 systems.
- VMware: A commercial virtualization platform for x86 systems.
- Docker: A containerization platform for Linux systems.
