Re: [libvirt] [PATCH] Support configuration of huge pages in guests

* configure.in: Add check for mntent.h * qemud/libvirtd_qemu.aug, qemud/test_libvirtd_qemu.aug, src/qemu.conf Add 'hugetlbfs_mount' config parameter * src/qemu_conf.c, src/qemu_conf.h: Check for -mem-path flag in QEMU, and pass it when hugepages are requested. Load hugetlbfs_mount config parameter, search for mount if not given. * src/qemu_driver.c: Free hugetlbfs_mount/path parameter in driver shutdown. Create directory for QEMU hugepage usage, chowning if required. * docs/formatdomain.html.in: Document memoryBacking/hugepages elements * docs/schemas/domain.rng: Add memoryBacking/hugepages elements to schema * src/util.c, src/util.h, src/libvirt_private.syms: Add virFileFindMountPoint helper API * tests/qemuhelptest.c: Add -mem-path constants * tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c: Add tests for hugepage handling * tests/qemuxml2argvdata/qemuxml2argv-hugepages.xml, tests/qemuxml2argvdata/qemuxml2argv-hugepages.args: Data files for hugepage tests --- configure.in | 2 +- docs/formatdomain.html | 8 +++- docs/formatdomain.html.in | 8 +++ docs/schemas/domain.rng | 9 ++++ qemud/libvirtd_qemu.aug | 1 + qemud/test_libvirtd_qemu.aug | 4 ++ src/domain_conf.c | 10 ++++- src/domain_conf.h | 1 + src/libvirt_private.syms | 1 + src/qemu.conf | 13 +++++ src/qemu_conf.c | 49 ++++++++++++++++++++ src/qemu_conf.h | 3 + src/qemu_driver.c | 34 ++++++++++++++ src/util.c | 37 ++++++++++++++- src/util.h | 4 ++ tests/qemuhelptest.c | 6 ++- tests/qemuxml2argvdata/qemuxml2argv-hugepages.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-hugepages.xml | 25 ++++++++++ tests/qemuxml2argvtest.c | 7 ++- tests/qemuxml2xmltest.c | 1 + 20 files changed, 217 insertions(+), 7 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hugepages.xml
