[ubuntu] vmbuilder generated disk file size

view story

http://ubuntuforums.org – vmbuilder creates small disk files for kvm and vmw6 hypervisor machines and full-sized disk files for esxi hypervisor machines. I didn't specify any disk pre-allocation options (I don't even know if there is such a thing for vmbuilder). The following VMs were created using the same command, with the exception of the hypervisor choice. ubuntu-esxi: total 11G -rw-r--r-- 1 aaron.smith aaron.smith 3.0G Sep 11 16:55 tmpb9a4Ke-flat.vmdk -rwx---r-x 1 aaron.smith aaron.smith 487 Sep 11 16:55 tmpb9a4Ke.vmdk* -rw-r--r-- 1 aaron.smith aaron.smith 7.9G Sep 11 16:55 tmpsuqqPO-flat.vmdk -rwx- (Hardware)
