Wait to receive QMP greeting before sending any monitor commands
Technically speaking we should wait until we receive the QMP greeting message before attempting to send any QMP monitor commands. Mostly we've got away with this, but there is a race in some QEMU which cause it to SEGV if you sent it data too soon after startup. Waiting for the QMP greeting avoids the race Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
