Domain Cloning

Once a template system has been installed, that system can be cloned. Use the following script to clone your template

clonedomain.sh

LVM_GROUP="vg2"

NAME_ORIGINAL="stretch-template"
LVM_NAME_ORIGINAL="kvm_${NAME_ORIGINAL}_vda"
LVM_SIZE_ORIGINAL=`lvs /dev/${LVM_GROUP}/${LVM_NAME_ORIGINAL} -o LV_SIZE --noheadings --units B --nosuffix`
NAME_CLONE="stretch-clone"
LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"


if [ $# -eq 0 ]
then
        echo "${0}: domain-name"
else
        NAME_CLONE=${1}
        LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"
fi

if [ ! -e /dev/${LVM_GROUP}/${LVM_NAME_CLONE} ]
then
        # create lvm partition
        lvcreate --size ${LVM_SIZE_ORIGINAL}B --name ${LVM_NAME_CLONE} ${LVM_GROUP}

        # clone the domain
        virt-clone --original ${NAME_ORIGINAL} --name ${NAME_CLONE} --file /dev/${LVM_GROUP}/${LVM_NAME_CLONE} --check path_in_use=off,path_exists=off
else
        echo "${0}: refusing to overwrite existing domain"
fi
