Hello Navine,

Avocado-vt uses `qmp` monitor by default. The `drive_add` was not yet accepted upstream (and probably won't be) in qmp monitor and is only available in unbreakable linux (RHEL) via experimental `__com.redhat_drive_add` command. You can still run this test on upstream qemu by using human monitor. You can force the monitor type by using `--vt-extra-params monitor_type=human` on the command line.

Kind regards,
Lukáš
