[libvirt] [PATCH 0/6 v8] Unprivleged SG_IO support

As a result of RFC [1], this implements the unprivleged SG_IO support. 1/6 and 2/6 are already acked. v7 - v8: * Change the XML tag name from "cdbfilter" to "sgio", and to leave enough room for future values, the values of "sgio" are "filtered" and "unfiltered" now. v6 - v7: * No restoring of unpriv_sgio per Daniel's thought. * Use "major:minor" as the hash key per Jirka's suggestion. Osier Yang (6): util: Prepare helpers for unpriv_sgio setting qemu: Add a hash table for the shared disks docs: Add docs and rng schema for new XML tag sgio conf: Parse and format the new XML qemu: qemu: set unpriv_sgio when starting domain and attaching disk qemu: Check if the shared disk's cdbfilter conflicts with others docs/formatdomain.html.in | 14 ++- docs/schemas/domaincommon.rng | 54 +++++--- src/conf/domain_conf.c | 55 ++++++-- src/conf/domain_conf.h | 10 ++ src/libvirt_private.syms | 4 + src/qemu/qemu_conf.c | 86 ++++++++++++ src/qemu/qemu_conf.h | 12 ++ src/qemu/qemu_driver.c | 30 ++++ src/qemu/qemu_process.c | 99 ++++++++++++++ src/qemu/qemu_process.h | 4 + src/util/util.c | 140 ++++++++++++++++++++ src/util/util.h | 13 ++ ...qemuxml2argv-disk-scsi-lun-passthrough-sgio.xml | 32 +++++ tests/qemuxml2xmltest.c | 1 + 14 files changed, 522 insertions(+), 32 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-scsi-lun-passthrough-sgio.xml [1] https://www.redhat.com/archives/libvir-list/2012-November/msg00988.html [2] https://www.redhat.com/archives/libvir-list/2012-December/msg00325.html Regards, Osier
