[Bug 1090223] Re: The directory ubuntu-kvm disappeared after creating vms failed

[whuang]

Sorry, it should not be a bug, but a misleading option.

According to the official virtualization guide:
http://doc.ubuntu.com/ubuntu/serverguide/C/jeos-and-vmbuilder.html
"the -o tells vmbuilder to overwrite the previous version of the VM"
The users should suppose to overwrite ONLY the VM.

But the manpages of vmbuilder tells
" -o, --overwrite
              Force overwrite of destination directory if it already exist. [default: False]"
It will delete the whole directory which may contains many VMs.

Is it too dangerous?
Will it make more sense if the "-o" option only overwrite the VM with the same "--hostname"?
