hmp: Make "info block" output more readable

Enterprise / Virtualization / QEMU - Kevin Wolf [redhat.com] - 28 June 2013 15:14 UTC

HMP is meant for humans and you should notice it.

This changes the output format to use a bit more space to display the information more readable and leaves out irrelevant information (e.g. mention only that an image is encrypted, but not when it's not; display I/O limits only if throttling is in effect; ...)

Before:

(qemu) info block ide0-hd0: removable=0 io-status=ok file=/tmp/overlay.qcow2 backing_file=/tmp/backing.img backing_file_depth=1 ro=0 drv=qcow2 encrypted=1 bps=0 bps_rd=0 bps_wr=0 iops=1024 iops_rd=0 iops_wr=0 ide1-cd0: removable=1 locked=0 tray-open=0 io-status=ok file=/home/kwolf/images/iso/Fedora-18-x86_64-Live-Desktop.iso ro=1 drv=raw encrypted=0 bps=0 bps_rd=0 bps_wr=0 iops=0 iops_rd=0 iops_wr=0 floppy0: removable=1 locked=0 tray-open=0 [not inserted] sd0: removable=1 locked=0 tray-open=0 [not inserted]

After:

(qemu) info block ide0-hd0: /tmp/overlay.qcow2 (qcow2, encrypted) Backing file: /tmp/backing.img (chain depth: 1) I/O limits: bps=0 bps_rd=0 bps_wr=0 iops=1024 iops_rd=0 iops_wr=0

ide1-cd0: /home/kwolf/images/iso/Fedora-18-x86_64-Live-Desktop.iso (raw, read-only) Removable device: not locked, tray closed

floppy0: [not inserted] Removable device: not locked, tray closed

sd0: [not inserted] Removable device: not locked, tray closed
