Comment 2 Laurent Vivier 2017-11-24 10:24:33 UTC

There is no "nested" parameter for kvm on POWER. So I think we can just remove the file.

Comment 3 Laurent Vivier 2017-11-24 10:50:17 UTC

Adding cc: Eric Auger as the problem is the same for aarch64

Comment 6 Miroslav Rezanina 2017-11-28 10:53:19 UTC

Fix included in qemu-kvm-rhev-2.10.0-9.el7

Comment 7 Qunfang Zhang 2017-11-29 07:58:51 UTC

Verified qemu-kvm-rhev-2.10.0-9.el7 on Power8,9, s390x and x86_84:

(1) Power:

# cat /etc/modprobe.d/kvm.conf 
#
# User changes in this file are preserved across upgrades.
#

Also checked s390x and x86_64:

(2) s390x:

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

(3) x86_64:
# cat /etc/modprobe.d/kvm.conf 
# 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


Based on above, the issue is fixed.  Thanks!
