|
|
#
|
|
# /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.
