			Some things to do first, though:
			# Create a new qcow2 file for the VM. See top of this document for an example.
			# Add a second disk drive to the VM. <code>virsh</code>'s <code>edit</code> command to edit the VM's XML config file. Attach to a new PCI bus instance. Change name from <code>vda</code> to <code>vdb</code>, too.
			# Restart (not just reboot -- qemu needs to stop to get the new VM config XML file) the VM.
			# In the VM, install:
			## parted
			## cryptsetup
			## dosfstools
			# And in the VM, partition the newly attached disk. We need a GUID partition table (GPT) because we're running UEFI firmare. I like parted for this, but use whatever tool works for you. Here's a <code>parted</code> session transcript:
			$ '''sudo parted /dev/vdb '''
			GNU Parted 3.6
			Using /dev/vdb
			Welcome to GNU Parted! Type 'help' to view a list of commands.
			(parted) '''unit s'''
			(parted) '''mktable gpt'''
			(parted) '''mkpart EFI_boot 2048 2099199'''
			(parted) '''mkpart bpool 2099200 6293503'''
			(parted) '''mkpart data 6293504 134217693'''
			(parted) '''set 1 esp on'''
			(parted) '''p'''
			Model: Virtio Block Device (virtblk)
			Disk /dev/vdb: 134217728s
			Sector size (logical/physical): 512B/512B
			Partition Table: gpt
			Disk Flags:

			Number Start End Size File system Name Flags
			1 2048s 2099199s 2097152s EFI_boot boot, esp
			2 2099200s 6293503s 4194304s bpool
			3 6293504s 134217693s 127924190s data

			(parted) '''quit'''

			Information: You may need to update /etc/fstab.

			$
			Now, partition 3 of the new disk will get the LUKS encryption goodness:
			$ '''sudo cryptsetup luksFormat --verbose --hash sha512 --iter-time 30000 --key-size 512 --pbkdf argon2id --pbkdf-memory $((4 * 1024 * 1024)) /dev/vdb3'''

			WARNING!
			========
			This will overwrite data on /dev/vdb3 irrevocably.

			Are you sure? (Type 'yes' in capital letters): '''YES'''
			Enter passphrase for /dev/vdb3:
			Verify passphrase:
			Key slot 0 created.
			Command successful.
			$
			From here, follow the instructions in the ZFS on Linux [https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Bookworm%20Root%20on%20ZFS.html Debian Bookworm Root on ZFS] wiki page.
