Attach a volume to a VM. The VM must be in the same region as the volume. A volume can only be attached to one VM at a time — detach it first if it's already attached elsewhere.

A Cost-Optimized server keeps its volumes on its node: it takes the volumes created to attach to a Cost-Optimized server, and they attach to no other server. A volume created on its own attaches to General Purpose, CPU-Optimized and Windows servers.

Inside the guest, the volume appears as /dev/vdb, /dev/vdc, etc. (virtio-blk).
