By specifying <vendor> element in CPU requirements a guest can be restricted to run only on CPUs by a given vendor. Host CPU vendor is also specified in capabilities XML. The vendor is checked when migrating a guest but it's not forced, i.e., guests configured without <vendor> element can be freely migrated.

All features in the baseline CPU definition were always created with policy='require' even though an arch driver returned them with different policy settings.

Adds ability to provide a preferred CPU model for CPUID data decoding. Such model would be considered as the best possible model (if it's supported by hypervisor) regardless on number of features which have to be added or removed for describing required CPU.

Useful mainly for migration. cpuUpdate changes guest CPU requirements in the following way: - match == "strict" || match == "exact" - optional features which are supported by host CPU are changed into required features - optional features which are not supported by host CPU are disabled - all other features remain untouched - match == "minimum" - match is changed into "exact" - optional features and all features not mentioned in guest CPU specification which are supported by host CPU become required features - other optional features are disabled - all other features remain untouched This ensures that no feature will suddenly disappear from the guest after migration.

Baseline CPU is the best CPU which can be used for a guest on any of the hosts.

All other libvirt functions use array first and then number of elements in that array. Let's make cpuDecode follow this rule. Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

The virConnectPtr is no longer required for error reporting since that is recorded in a thread local. Remove use of virConnectPtr from all APIs in cpu_conf.{h,c} and update all callers to match

Each driver supporting CPU selection must fill in host CPU capabilities. When filling them, drivers for hypervisors running on the same node as libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers, such as VMware, need to implement their own way of getting such data. Raw data can be decoded into virCPUDefPtr using cpuDecode() function. When implementing virConnectCompareCPU(), a hypervisor driver can just call cpuCompareXML() function with host CPU capabilities. For each guest for which a driver supports selecting CPU models, it must set the appropriate feature in guest's capabilities: virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0) Actions needed when a domain is being created depend on whether the hypervisor understands raw CPU data (currently CPUID for i686, x86_64 architectures) or symbolic names has to be used. Typical use by hypervisors which prefer CPUID (such as VMware and Xen): - convert guest CPU configuration from domain's XML into a set of raw data structures each representing one of the feature policies: cpuEncode(conn, architecture, guest_cpu_config, &forced_data, &required_data, &optional_data, &disabled_data, &forbidden_data) - create a mask or whatever the hypervisor expects to see and pass it to the hypervisor Typical use by hypervisors with symbolic model names (such as QEMU): - get raw CPU data for a computed guest CPU: cpuGuestData(conn, host_cpu, guest_cpu_config, &data) - decode raw data into virCPUDefPtr with a possible restriction on allowed model names: cpuDecode(conn, guest, data, n_allowed_models, allowed_models) - pass guest->model and guest->features to the hypervisor * src/cpu/cpu.c src/cpu/cpu.h src/cpu/cpu_generic.c src/cpu/cpu_generic.h src/cpu/cpu_map.c src/cpu/cpu_map.h src/cpu/cpu_x86.c src/cpu/cpu_x86.h src/cpu/cpu_x86_data.h * configure.in: check for CPUID instruction * src/Makefile.am: glue the new files in * src/libvirt_private.syms: add new private symbols * po/POTFILES.in: add new cpu files containing translatable strings
