I can't comment much on the code, but I'm supportive of QEMU gaining this feature, because it addresses a number of use cases not satisfied by using iSCSI via the host OS's block layer. > >>> You can specify devices using a iscsi url of the form : > >>> iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> > >>> When using authentication, the password can optionally be set with > >>> LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process > >>> list I'm not a fan of sending passwords via command line args, or environment variables. Env variables *can* be exposed via the process list, albeit not to unprivileged users. More critically, env variables will end up in logfiles like /var/log/libvirt/qemu/$GUESTNAME.log, and in data reported to distro bug trackers, via tools like sosreport which capture /proc/$PID/environ and aforementioned logfiles. We have a similar requirement for specifying passwords with the Ceph/RBD driver, and also for the curl/HTTP block drivers. We have a monitor command for providing decryption passwords for QCow2 disks. We could either reuse that for connection passwords, or perhaps slightly better would be to have a separate command for connection passwords.
