Re: [libvirt] [PATCH] Support 'block_passwd' command for QEMU disk encryption

The old text mode monitor prompts for a password when disks are encrypted. This interactive approach doesn't work for JSON mode monitor. Thus there is a new 'block_passwd' command that can be used. * src/qemu/qemu_driver.c: Split out code for looking up a disk secret from findVolumeQcowPassphrase, into a new method getVolumeQcowPassphrase. Enhance qemuInitPasswords() to also set the disk encryption password via the monitor * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h, src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add support for the 'block_passwd' monitor command. --- src/qemu/qemu_driver.c | 117 +++++++++++++++++++++++++++++------------- src/qemu/qemu_monitor.c | 15 +++++ src/qemu/qemu_monitor.h | 4 ++ src/qemu/qemu_monitor_json.c | 33 ++++++++++++ src/qemu/qemu_monitor_json.h | 4 ++ src/qemu/qemu_monitor_text.c | 47 +++++++++++++++++ src/qemu/qemu_monitor_text.h | 4 ++ 7 files changed, 188 insertions(+), 36 deletions(-)
