Description David Hildenbrand 2017-11-10 15:22:08 UTC

Description of problem:
kvm.conf is currently x86 specific

Steps to Reproduce:
1. cat kvm.conf

Actual results:

# Setting modprobe kvm_intel/kvm_amd nested = 1
# only enables Nested Virtualization until the next reboot or
# module reload. Uncomment the option applicable
# to your system below to enable the feature permanently.
#
# User changes in this file are preserved across upgrades.
#
# For Intel
#options kvm_intel nested=1
#
# For AMD
#options kvm_amd nested=1

Expected results:

# Setting modprobe kvm nested = 1
# only enables Nested Virtualization until the next reboot or
# module reload. Uncomment the option applicable
# to your system below to enable the feature permanently.
#
# User changes in this file are preserved across upgrades.
#
#options kvm nested=1
