Michal Privoznik 220c0031fe qemuDomainAttachDeviceFlags: Parse device xml as inactive
In all other drivers we are doing so. Moreover, we don't want to parse
runtime information in attach (even if the attach is meant as live)
because we are generating the runtime info ourselves. We can't trust
users they supply sane values anyway.

==1140== 9 bytes in 1 blocks are definitely lost in loss record 72 of 1,151
==1140==    at 0x4A06C2B: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)

==1140==    by 0x5241F81: virNetServerProgramDispatchCall (virnetserverprogram.c:437)

When doing live attach, we are passing the inactive definition anyway
since we are passing the result of virDomainDeviceDefCopy() which does
inactive copy by default.

Moreover, we are doing the same mistake in qemuhotplugtest.

Just a side note - it makes perfect sense to parse the runtime info
like alias in qemuDomainDetachDevice and qemuDomainUpdateDeviceFlags()
as in some cases the only difference to distinguish two devices can be
just their alias.

         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.

Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
