Although the commands are very simple and just 2-3 steps but I keep forgetting them and hence wrote the following script:

The script takes input as “ova” filename and then creates the qcow2 image and finally a VM for you.

#!/bin/bash -

#          FILE: ova2vm.sh

#         USAGE: ./ova2vm.sh

set -o nounset                              # Treat unset variables as an error

if [[ $# == 0 ]]
then
    echo "You need to provide ova/vmdk filename"
    exit
fi
if [[ $1 == *ova ]]
then
    tmp=$(mktemp -d /tmp/amitXXXXXXX)
    cd  $tmp
    tar xvf $1
    file=$(echo $PWD/*vmdk)
else
    file=$1
    echo "Not a OVA file"
fi
dfile="$dest/$(basename $file)"

read -p "Enter the name for VM" vmname
qemu-img convert $file $dfile -p -c -O qcow2
virt-install --disk $dfile --ram 512 \
    --virt-type kvm --vcpus 1 --name "$vmname" --import
