If source is file then -object memory-backend-file,id=mem,size=1024M,mem- path=/var/lib/libvirt/qemu -numa node,memdev=mem Should be added to the qemu commandline If access is shared then the share=on parameter should be added to the memory-backend-file e.g. -object memory-backend-file,id=mem,size=1024M,mem- path=/var/lib/libvirt/qemu,share=on Also token memAccess in numa cell is used (if not present, default value from memoryBacking is used) Jaroslav Safka (2): Add support for preallocated fd memory Add support for preallocated fd memory docs/schemas/domaincommon.rng | 30 ++++ src/conf/domain_conf.c | 138 +++++++++++++----- src/conf/domain_conf.h | 33 +++++ src/qemu/qemu_command.c | 156 ++++++++++++++++----- src/qemu/qemu_command.h | 4 + .../qemuxml2argv-fd-memory-no-numa-topology.args | 33 +++++ .../qemuxml2argv-fd-memory-no-numa-topology.xml | 91 ++++++++++++ .../qemuxml2argv-fd-memory-numa-topology.args | 33 +++++ .../qemuxml2argv-fd-memory-numa-topology.xml | 94 +++++++++++++ .../qemuxml2argv-fd-memory-numa-topology2.args | 36 +++++ .../qemuxml2argv-fd-memory-numa-topology2.xml | 95 +++++++++++++ .../qemuxml2argv-fd-memory-numa-topology3.args | 39 ++++++ .../qemuxml2argv-fd-memory-numa-topology3.xml | 96 +++++++++++++ .../qemuxml2argv-memorybacking-set.xml | 32 +++++ .../qemuxml2argv-memorybacking-unset.xml | 32 +++++ tests/qemuxml2argvtest.c | 42 ++++++ .../qemuxml2xmlout-memorybacking-set.xml | 40 ++++++ .../qemuxml2xmlout-memorybacking-unset.xml | 40 ++++++ tests/qemuxml2xmltest.c | 3 + 19 files changed, 1001 insertions(+), 66 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-no-numa-topology.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-no- numa-topology.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology2.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology2.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology3.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory- numa-topology3.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv- memorybacking-set.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv- memorybacking-unset.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout- memorybacking-set.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout- memorybacking-unset.xml -- 2.7.4
