i create qcow2 format image with -o encryption, and assign password. but when i qemu-img info encryt.qcow2 , it display encryt.qcow2 info no master what i input, even just hit enter. the 'Password Authentication ' of qemu-img may be invalid.
thanks. my steps: -------- Create an encrypted disk #qemu-img create -e -f qcow2 image.qcow2 10G If you pass the option -e or -o encryption when you create an image, the resulting image will be encrypted, with an empty (blank) password – there is no option to set a password in a single step at the time of creation. To set a password, again use qemu-img , but this time with the convert option #qemu-img convert -e -O qcow2 image.qcow2 encrypted.qcow2 You will be asked to give a password twice. At the first prompt hit enter (as the password is blank), at the second prompt you will set the password for your resulting encrypted disk. ------------ [root@kvm images]# qemu-img info encryped.qcow2 Disk image 'encryped.qcow2' is encrypted. password: image: encryped.qcow2 file format: qcow2 virtual size: 8.0G (8589934592 bytes) disk size: 136K encrypted: yes cluster_size: 65536
