[libvirt] [PATCH v12 00/11] Write separate module for hostdev passthrough

These patches implements a separate module for hostdev passthrough so that it could be shared by different drivers and can maintain a global state of a host device. patch 1/11: pci/usb/scsi used_by should include driver and domain info to check conflict among different drivers. patch 2/11~5/11: extract qemu specific code outside, to prepare for hostdev common library patch 6/11: move hostdev functions from qemu_hostdev.c to common library and maintain insistent device state. patch 7/11: add a unit test for hostdev common library. patch 8/11: switch qemu driver to use the common library instead of its own hostdev passthrough APIs. patch 9/11: switch lxc driver to use the common library instead of its own hostdev passthrough APIs. patch 10/11: add a hostdev pci backend type for xen usage. patch 11/11: add pci passthrough to libxl driver. --- Changes to v11: * rebase to latest shareable scsi hostdev changes * split v11 1/6 (add hostdev common library): add some small patches to extract qemu specific codes outside first before adding hostdev common library patch, for easier review. Chunyan Liu (11): change used_by: specify both driver and domain qemu_hostdev: move cfg->relaxedACS as a flag qemu_hostdev: move COLD_BOOT as a flag qemu_hostdev: parse BACKEND_DEFAULT outside qemu_hostdev: add/remove share device outside add hostdev passthrough common library add unit test for hostdev common library change qemu driver to use hostdev common library change lxc driver to use hostdev common library add hostdev pci backend type for xen add pci passthrough for libxl driver .gitignore | 1 + docs/schemas/domaincommon.rng | 1 + po/POTFILES.in | 3 +- src/Makefile.am | 3 +- src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 21 + src/libxl/libxl_conf.c | 63 + src/libxl/libxl_conf.h | 4 + src/libxl/libxl_domain.c | 9 + src/libxl/libxl_driver.c | 448 +++++- src/lxc/lxc_conf.h | 4 - src/lxc/lxc_driver.c | 47 +- src/lxc/lxc_hostdev.c | 413 ----- src/lxc/lxc_hostdev.h | 43 - src/lxc/lxc_process.c | 24 +- src/qemu/qemu_command.c | 4 +- src/qemu/qemu_conf.h | 11 +- src/qemu/qemu_domain.c | 22 + src/qemu/qemu_driver.c | 83 +- src/qemu/qemu_hostdev.c | 89 +- src/qemu/qemu_hostdev.h | 5 +- src/qemu/qemu_hotplug.c | 144 +- src/qemu/qemu_process.c | 61 +- src/util/virhostdev.c | 1787 ++++++++++++++++++++ src/util/virhostdev.h | 134 ++ src/util/virpci.c | 30 +- src/util/virpci.h | 9 +- src/util/virscsi.c | 30 +- src/util/virscsi.h | 7 +- src/util/virusb.c | 29 +- src/util/virusb.h | 8 +- tests/Makefile.am | 5 + .../qemuxml2argv-hostdev-pci-address.xml | 1 + .../qemuxml2argvdata/qemuxml2argv-net-hostdev.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-pci-rom.xml | 2 + tests/virhostdevtest.c | 473 ++++++ tests/virscsitest.c | 6 +- 38 files changed, 3292 insertions(+), 737 deletions(-) delete mode 100644 src/lxc/lxc_hostdev.c delete mode 100644 src/lxc/lxc_hostdev.h create mode 100644 src/util/virhostdev.c create mode 100644 src/util/virhostdev.h create mode 100644 tests/virhostdevtest.c
