# This explorer tries to determine what type of machine the target to be
|
||||
# configured is (container, virtual machine, bare-metal).
|
||||
#
|
||||
# It will print one line for each layer it can detect.
|
||||
# The format of all lines is: TYPE[ VERB VENDOR]
|
||||
#
|
||||
# VERB does not have a special meaning, it is just for better readability.
|
||||
#
|
||||
# e.g.
|
||||
# container on lxc
|
||||
# virtual by kvm-spapr
|
||||
#
|
||||
# The third word of each line can be composed of different parts concatenated with a `-'
|
||||
# (minus) character, with each component being a specification of the previous,
|
||||
# e.g.:
|
||||
# - lxc-libvirt (LXC container, managed by libvirt)
|
||||
# - lpar-s390 / lpar-power (LPAR running on IBM S/390 or POWER, respectively)
|
||||
# - xen-hvm / xen-pv (Xen HVM vs para-virtualization)
|
||||
#
|
||||
# If this explorer cannot determine any information it will print nothing.
