Re: confusion on KVM virtualization (debian admin handbook)

Thanks for sharing your thought.

just learn from some where, that "creating disk with virt-install can only create raw on the other hand qcow2 first needs to be initiated as volume"

Thanks,

I think it's mostly six of one and half a dozen of the other. If you are
not using sparse volumes, disk creation can take quite a lot of time, so
it might be logistically easier to batch the creation of a lot of
volumes before you start installing VMs, especially if you need to
re-run the install process a few times as you tweak parameters.
