Mostly: iotests has been using the new interface for the 6.2 release testing cycle and we didn't find many bugs, so I'm assuming we can largely switch these, too.

The problem is that the backing errors originally emitted by a blocking socket may no longer be exactly those raised by the async core, so it's not 1:1. In this case, the new QMP library always raises qemu.[a]qmp.ConnectError, and that houses a backing exception with the "real reason". that "real reason" may be the built-in ConnectionError, which just indicates some kind of connection problem, including ECONNREFUSED. So the scope of this exception has expanded a little. > > Nothing seems wrong to me, so weak: > Reviewed-by: Vladimir Sementsov-Ogievskiy <vsement...@virtuozzo.com> > > -- > Best regards, > Vladimir > >
