Zfs send and receive to migrate a VM

Here is a tutorial on how to use zfs send and zfs recv to migrate a virtual machine (VM) from one system to another:

1. On the source system, create a snapshot of the ZFS file system that contains the VM:

zfs snapshot pool/filesystem@snapshot

2. Send the snapshot to the destination system over the network:

zfs send pool/filesystem@snapshot | ssh destination "zfs recv pool/filesystem"

3. On the destination system, list the received snapshot to verify that it was received successfully:

zfs list -t snapshot

4. (Optional) If the VM is running on the source system, you can stop it before sending the snapshot to ensure that the VM is in a consistent state.
5. (Optional) If the VM is a Linux system, you may need to update the boot loader (e.g. GRUB) on the destination system to ensure that the VM can boot properly after the migration.
