[libvirt] [PATCH 0/2] Add support for preallocated fd memory

Hi the xml element to be extended with additional children is the memoryBacking element. We would like to introduce 3 new elements source,access and allocation <memoryBacking> <source type="file|anonymous" path='/path/to/qemu/'/> <access Mode="shared|private"/> <allocation mode="immediate|ondemand"/> </memoryBacking> If allocation is immediate then -mem-prealloc should be added to the qemu commanline. 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 Jaroslav Safka (2): Add support for preallocated fd memory Add support for preallocated fd memory docs/schemas/domaincommon.rng | 37 +++++ src/conf/domain_conf.c | 149 +++++++++++++++----- src/conf/domain_conf.h | 34 +++++ src/qemu/qemu_command.c | 156 ++++++++++++++++----- src/qemu/qemu_command.h | 4 + .../qemuxml2argv-fd-memory-no-numa-topology.args | 34 +++++ .../qemuxml2argv-fd-memory-no-numa-topology.xml | 96 +++++++++++++ .../qemuxml2argv-fd-memory-numa-topology.args | 34 +++++ .../qemuxml2argv-fd-memory-numa-topology.xml | 99 +++++++++++++ .../qemuxml2argv-memorybacking-set.xml | 32 +++++ .../qemuxml2argv-memorybacking-unset.xml | 32 +++++ tests/qemuxml2argvtest.c | 24 ++++ .../qemuxml2xmlout-memorybacking-set.xml | 40 ++++++ .../qemuxml2xmlout-memorybacking-unset.xml | 40 ++++++ tests/qemuxml2xmltest.c | 3 + 15 files changed, 748 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-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 -- 2.5.5 -------------------------------------------------------------- Intel Research and Development Ireland Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
