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"? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vm-builder in Ubuntu. https://bugs.launchpad.net/bugs/1090223 Title: The directory ubuntu-kvm disappeared after creating vms failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vm-builder/+bug/1090223/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
