Re: [libvirt] [PATCH v7 0/9] Add setting CPU features (CPUID) with libxenlight driver.

Add support for CPUID setting based on <cpu> element. Since libxl format support only adjusting specific bits over host CPU, only mode='host-passthrough' is supported - other values are rejected (including default 'custom'). This will break some configurations working before (bare <cpu> element with for example NUMA configuration), but libxl driver never supported full 'custom' mode - it was silently ignored, which might lead to some unexpected effects. Since mode='host-passthrough' is now necessary to specify CPU options, do not enable nested HVM feature by mere presence of this element, require also enabling it in libxl.conf. Nested HVM is still in "preview" state, so better be explicit here. v2 of this patch series: https://www.redhat.com/archives/libvir-list/2017-July/msg00050.html v3 of this patch series: https://www.redhat.com/archives/libvir-list/2017-December/msg00314.html v4 of this patch series: https://www.redhat.com/archives/libvir-list/2018-February/msg00504.html v5 of this patch series: https://www.redhat.com/archives/libvir-list/2018-March/msg00796.html v6 of this patch series: https://www.redhat.com/archives/libvir-list/2018-March/msg01310.html Marek Marczykowski-Górecki (9): libxl: fix libxlDriverConfigDispose for partially constructed object libxl: pass driver config to libxlMakeDomBuildInfo libxl: warn about ignored CPU mode=custom libxl: do not enable nested HVM unless global nested_hvm option enabled xenconfig: do not override def->cpu if already set elsewhere libxl: add support for CPUID features policy tests: check CPU features handling in libxl driver xenconfig: add CPUID handling to domXML <-> xl.cfg conversion tests: add test case for CPUID in xenconfig driver src/libxl/libvirtd_libxl.aug | 2 +- src/libxl/libxl.conf | 8 +- src/libxl/libxl_conf.c | 66 +++- src/libxl/libxl_conf.h | 6 +- src/libxl/libxl_domain.c | 2 +- src/libxl/test_libvirtd_libxl.aug.in | 1 +- src/xenconfig/xen_xl.c | 236 ++++++++++++++-- src/xenconfig/xen_xl.h | 2 +- tests/libxlxml2domconfigdata/fullvirt-cpuid.json | 60 ++++- tests/libxlxml2domconfigdata/fullvirt-cpuid.xml | 34 ++- tests/libxlxml2domconfigtest.c | 27 +- tests/virmocklibxl.c | 31 ++- tests/xlconfigdata/test-fullvirt-cpuid.cfg | 25 ++- tests/xlconfigdata/test-fullvirt-cpuid.xml | 36 ++- tests/xlconfigtest.c | 1 +- 15 files changed, 492 insertions(+), 45 deletions(-) create mode 100644 tests/libxlxml2domconfigdata/fullvirt-cpuid.json create mode 100644 tests/libxlxml2domconfigdata/fullvirt-cpuid.xml create mode 100644 tests/xlconfigdata/test-fullvirt-cpuid.cfg create mode 100644 tests/xlconfigdata/test-fullvirt-cpuid.xml base-commit: dffe584aa4194b0667924632e9e1ae12c5520956
