Michal Privoznik	88957116c9	qemu: Use memory-backend-* for regular guest memory ... So far, Libvirt configures memory-backend-* for memory hotplug, possibly NUMA nodes and in a few other cases. This patch switches to constructing the memory-backend-* command line for all cases. To keep ability to migrate guests a little hack is used: the ID of the object is set to the one that QEMU uses internally anyways. These IDs are stable (first started to appear somewhere around v0.13.0-rc0~96) and can't change. In fact, this patch does exactly what QEMU does internally. The reason for moving the logic into Libvirt is that QEMU wants to deprecate the old style of specifying memory. So far, only x84_64 test cases are changed, because tests for other architectures use older capabilities, which still lack the QEMU_CAPS_MACHINE_MEMORY_BACKEND capability and they don't report the RAM ID.

Laine Stump	2d3cf60328	qemu: hook up pcie-root-port hotplug='off' option ... If a pcie-root-port or pcie-downstream-port has hotplug='off' in its <target> subelement, and if the qemu binary supports the hotplug=false option, then it will be added to the commandline for the pcie controller. This controller will then not allow any hotplug/unplug of devices while the guest is running (and the hotplug capability won't be advertised to the guest OS, so the guest OS also won't present unplugging of PCI devices as an option). <controller type='pci' model='pcie-root-port'> <target hotplug='off'/> </controller> For any PCI controllers other than pcie-downstream-port and pcie-root-port, of for qemu binaries that don't support the hotplug commandline option, an error will be logged during validation.
