Add a nested_virt option about kubevirt-apb HOT 9 CLOSED

To support both Intel and AMD:

if [ -d /sys/module/kvm_intel -a -d /etc/modprobe.d -a ! -f /etc/modprobe.d/kvm-intel.conf ]; then
    echo "options kvm-intel nested=1" > /etc/modprobe.d/kvm-intel.conf
    rmmod kvm-intel && modprobe kvm-intel || true
fi
if [ -d /sys/module/kvm_amd -a -d /etc/modprobe.d -a ! -f /etc/modprobe.d/kvm-amd.conf ]; then
    echo "options kvm-amd nested=1" > /etc/modprobe.d/kvm-amd.conf
    rmmod kvm-amd && modprobe kvm-amd || true
fi

To verify:

cat /sys/module/kvm_intel/parameters/nested

from kubevirt-apb.

i'll be a bit picky and suggest modprobe -r instead of rmmod

from kubevirt-apb.

@karmab can you explain further?

from kubevirt-apb.

@rthallisey sure, you re saying in first comment the following

In order for this to work, the container needs to be a root user and needs to mount in /lib/modules.

and it dont get which container you re talking about:

• the kubevirt ones
• the apb one

from kubevirt-apb.

The kubevirt-apb need to be root and mount /lib/modules.
