i have been going through Administration handbook and got confused in KVM virtualization section.
Book teaches us to create volume first then assign it to vm with Virt-install command however, we can also create image on runtime with virt-install command. we do not need volume to be set before creating a VM. so my question is what is the difference b/w the two methods.
if i create Volume first then assign or if i create image directly from virt-installl command what are the pros and cons.
