Hi all,
I did some investigation and found that "virsh qemu-monitor-command" supports qom-get,
but qemu hmp doesn't. However, in hmp.c there are qom_list and qom_set. It confused me
and my question is: why is this? And how can I get a property's value in hmp? e.g.
qemu-system-* -nodefaults -machine accel=qtest -no-shutdown -nographic -monitor stdio -serial none -hda /root/t.qcow2
"info qtree" can only get a few properties.

Thanks a lot!
