using either the latest raring full server iso, or a minimal netinst image from release=raring arch=amd64 f=${release}-mini-${arch}.iso wget -O $f http://archive.ubuntu.com/ubuntu/dists/${release}/main/installer-${arch}/current/images/netboot/mini.iso status: incomplete ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155403 Title: virtio cdrom detected as hard disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1155403/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
