Commit 6534b3c4 tried to raise an error when there is no numa nodes by setting access='shared' in the domain config, but added a helper called from qemuDomainDeviceDefValidate instead of a helper called from qemuDomainDefValidate for XML: <memoryBacking> <hugepages/> <access mode='shared'/> </memoryBacking> Since there are no memory devices in the test XML, there would be no validation failure, but the test added was still failing. Investigating that it turns out that unnecessary XML elements were causing the failure (no need for <video>, <graphics>, <pm>, usb controller model "piix3-uhci", disk attribute for "discard='unmap'", <serial>, <console>, <channel> and a memballoon model). Removing all those before moving the method caused the test to succeed. So this patch moves the validation to the right place and removes all the unnecessary XML pieces that were causing a false validation failure. https://bugzilla.redhat.com/show_bug.cgi?id=1448149#c14 Signed-off-by: Luyao Huang <lhuang@redhat.com> Reviewed-by: John Ferlan <jferlan@redhat.com>
Libvirt API for virtualization
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.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.

The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General

Installation
Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
While to build & install as an unprivileged user
$ ./configure --prefix=$HOME/usr
$ make
$ make install
The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the configure
script and a summary printed
which lists any missing (optional) dependencies.
