Domain Cloning
Once a template system has been installed, that system can be cloned. virt-clone will automatically change the MAC address of your network device.
Cloning
Use the script below to clone your template.
domain_clone.sh
1 #!/bin/sh
2
3 LVM_GROUP="vg2"
4 NAME_ORIGINAL="stretch-template"
5 LVM_NAME_ORIGINAL="kvm_${NAME_ORIGINAL}_vda"
6 LVM_SIZE_ORIGINAL=`lvs /dev/${LVM_GROUP}/${LVM_NAME_ORIGINAL} -o LV_SIZE --noheadings --units B --nosuffix`
7 NAME_CLONE="stretch-clone"
8 LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"
9
10 if [ $# -gt 0 ]
11 then
12 NAME_CLONE=${1}
13 LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"
14 fi
15
16 if [ ! -e /dev/${LVM_GROUP}/${LVM_NAME_CLONE} ]
17 then
18 # create lvm partition
19 lvcreate --size ${LVM_SIZE_ORIGINAL}B --name ${LVM_NAME_CLONE} ${LVM_GROUP}
20
21 # clone the domain
22 virt-clone --original ${NAME_ORIGINAL} --name ${NAME_CLONE} --file /dev/${LVM_GROUP}/${LVM_NAME_CLONE} --check path_in_use=off,path_exists=off
