[libvirt] [PATCH 0/6] Support for per-guest-node binding
by Martin Kletzander 26 Jun '14

26 Jun '14

Currently we are only able to bind the whole domain to some host nodes using the /domain/numatune/memory element. Numerous requests were made to support host<->guest numa node bindings, so this series tries to pinch an idea on how to do that using /domain/numatune/memnode elements. That is incompatible with automatic numa placement (numad) since that makes no sense. Also this disables any live changes to numa parameters (the /domain/numatune/memory settings) since we cannot change the settings given to qemu.

[libvirt] broken api.xml file
by Eric Blake 25 Jun '14

25 Jun '14

Nehal discovered by accident that our libvirt-api.xml file is broken, which in turn leads to broken python bindings. Right now, if you look at docs/libvirt-api.xml, you'll find: <enum name='VIR_IP_ADDR_TYPE_IPV4' file='libvirt' value='1' type='virIPAddrType'/> but if you look at the libvirt.h.in file, you see: typedef enum { VIR_IP_ADDR_TYPE_IPV4, VIR_IP_ADDR_TYPE_IPV6, which, by C rules, means that the enum is value 0, not 1. We need to fix whatever in libvirt is generating the api.xml file, because that in turn is leading to incorrect code in the python bindings. We could, of course, work around the bug by adding explicit 'VIR_IP_ADDR_TYPE_IPV4 = 0,' in our libvirt.h.in file, but I'd rather fix the root cause. It's not my area of expertise, so I'd appreciate a hand in finding the problem spot, although I'm still trying to take a look. We'll probably need to backport the patch to stable branches, and any distro that has picked up broken definitions will want to respin python bindings. In a quick audit, I found three impacted enums: virDomainCoreDumpFormat (such as VIR_DOMAIN_CORE_DUMP_FORMAT_RAW) virDomainEventGraphicsAddressType (such as VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4) virIPAddrType (such as VIR_IP_ADDR_TYPE_IPV4) -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

When CPU virConnectCompareCPU returns VIR_CPU_COMPARE_INCOMPATIBLE, the caller has no clue why the CPU is considered incompatible with host CPU.

This is basically a v2 of one of my previous attempts, but that was a different set. So practically it's still a v1. Michal Privoznik (5): virhostdev: Move IOMMU and VFIO funcs from qemu conf: Introduce viremulator_capabilities Introduce virConnectGetEmulatorCapabilities virsh: Expose virConnectGetEmulatorCapabilities qemu: Implement virConnectGetEmulatorCapabilities docs/formatemulatorcaps.html.in | 115 +++++++++++++ docs/schemas/Makefile.am | 1 + docs/schemas/emulatorcapability.rng | 75 +++++++++ docs/sitemap.html.in | 4 + include/libvirt/libvirt.h.in | 6 + libvirt.spec.in | 1 + mingw-libvirt.spec.in | 2 + src/Makefile.am | 3 +- src/conf/viremulator_capabilities.c | 139 +++++++++++++++ src/conf/viremulator_capabilities.h | 47 ++++++ src/driver.h | 7 + src/libvirt.c | 52 ++++++ src/libvirt_private.syms | 9 + src/libvirt_public.syms | 2 + src/qemu/qemu_capabilities.c | 78 +++++---- src/qemu/qemu_capabilities.h | 3 + src/qemu/qemu_capabilitiespriv.h | 55 ++++++ src/qemu/qemu_driver.c | 96 ++++++++++- src/qemu/qemu_hostdev.c | 76 +-------- src/qemu/qemu_hostdev.h | 2 - src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 19 ++- src/remote_protocol-structs | 10 ++ src/util/virhostdev.c | 73 ++++++++ src/util/virhostdev.h | 4 + tests/Makefile.am | 28 ++- .../viremulatorcaps-basic.xml | 5 + .../viremulatorcaps-qemu-kvm-vfio.xml | 17 ++ tests/viremulatorcapabilitiesschematest | 11 ++ tests/viremulatorcapabilitiestest.c | 187 +++++++++++++++++++++ tests/virhostdevmock.c | 40 +++++ tools/virsh-host.c | 74 ++++++++ tools/virsh.pod | 13 ++ 33 files changed, 1143 insertions(+), 112 deletions(-) create mode 100644 docs/formatemulatorcaps.html.in create mode 100644 docs/schemas/emulatorcapability.rng create mode 100644 src/conf/viremulator_capabilities.c create mode 100644 src/conf/viremulator_capabilities.h create mode 100644 src/qemu/qemu_capabilitiespriv.h create mode 100644 tests/viremulatorcapabilitiesdata/viremulatorcaps-basic.xml create mode 100644 tests/viremulatorcapabilitiesdata/viremulatorcaps-qemu-kvm-vfio.xml create mode 100755 tests/viremulatorcapabilitiesschematest create mode 100644 tests/viremulatorcapabilitiestest.c create mode 100644 tests/virhostdevmock.c -- 1.8.5.5
