From 887354bd13ecb7ff68ec26892806c97512b77877 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Fri, 10 Feb 2017 16:24:56 +0100 Subject: hmp: Request permissions in qemu-io The HMP command 'qemu-io' is a bit tricky because it wants to work on the original BlockBackend, but additional permissions could be required. The details are explained in a comment in the code, but in summary, just request whatever permissions the current qemu-io command needs.
