[PATCH 0/8] qemu: Use memory-backend-* for regular guest memory

DISCLAIMER: These patches depend on a yet not merged QEMU patch: https://lists.nongnu.org/archive/html/qemu-devel/2020-05/msg07255.html This is another round of patches that are adapting Libvirt to new QEMU command line so that they can deprecate the old one. See 8/8 for explanation. Michal Prívozník (8): qemuBuildMemoryBackendProps: Move @prealloc setting to backend agnostic part qemuBuildMemoryBackendProps: Respect //memoryBacking/allocation/@mode=immediate qemuBuildMemoryBackendProps: Prealloc mem for memfd backend qemuBuildMemoryBackendProps: Fix const correctness qemu: Introduce QEMU_CAPS_MACHINE_MEMORY_BACKEND qemu: Track default-ram-id machine attribute qemucapabilitiestest: Update 5.1.0 data qemu: Use memory-backend-* for regular guest memory src/qemu/qemu_capabilities.c | 42 ++- src/qemu/qemu_capabilities.h | 6 + src/qemu/qemu_capspriv.h
