# Copy this script to $vmpath. The filename should be the VM name. To ease
# snapshotting, each VM should be in its own directory, and should be a separate
# ZFS dataset. For example:

# /virt/vm/testvm <-- ZFS dataset.
# /virt/vm/testvm/testvm <-- This script.
# /virt/vm/testvm/testvm_disk0.img <-- Hard disk image.
# /virt/vm/testvm/cdrom.iso <-- Operating System install ISO.

# The VM will be named the same as this script filename, unless you change the
# vmname variable here.
