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="vg_storage"
   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}/${LVM_NAME_CLONE} --check path_in_use=off,path_exists=off
  23 else
  24         echo "${0}: refusing to overwrite existing domain"
  25 fi

Make a clone. 

./domain_clone.sh clone

Console Access

Remove console access by editing the domain.

Memory

Increase or decrease amount of memory by editing the domain.

Network

For your convenience add the MAC address to the DHCP servers lits of fixed IP-adresses before starting the system for the first time. This way you know beforehand which IP-address to connect to.

Guest OS

Continue by configuring the KVM Guest Operating System.
