Migrating Virtual Machines
Virtual machines are able to be migrated between servers that support hypervisors in the same region as the existing virtual machine.
Caution
At this time, virtual machine migrations are not live. A new copy of the virtual machine will be started on the target server before traffic is redirected.
Under the hood, Cycle uses the same system to migrate a virtual machine as a container instance. This means that volumes attached to the virtual machine will also be migrated to the target instance.
Target Server Requirements
A virtual machine may only be migrated to a server in the same region as the existing virtual machine, and to a server that supports the hypervisor feature. Virtual machines may only run on servers with this feature, and not all servers supported by Cycle have the hypervisor feature.
Network Considerations
When migrating a virtual machine, it will maintain its assigned IP addresses. As IP addresses are attached to the gateway service, the virtual machine is able to migrate freely between servers in the same region (hence the server restriction) without causing any change to networking.
