Re: [libvirt] [PATCH] qemu: Report errors from iohelper

Currently, we use iohelper when saving/restoring a domain. However, if there's some kind of error (like I/O) it is not propagated to libvirt. Since it is not qemu who is doing the actual write() it will not get error. The iohelper does. Therefore we should check for iohelper errors as it makes libvirt more user friendly. --- diff to v1: -incorporate the event loop to read iohelper's stderr
