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

XML schema for CPU flags Firstly, CPU topology and model with optional features have to be advertised in host capabilities: <host> <cpu> <arch>ARCHITECTURE</arch> <features> <!-- old-style features are here --> </features> <model>NAME</model> <topology sockets="S" cores="C" threads="T"/> <feature name="NAME"/> </cpu> ... </host> Secondly, drivers which support detailed CPU specification have to advertise it in guest capabilities: <guest> ... <features> <cpuselection/> </features> </guest> And finally, CPU may be configured in domain XML configuration: <domain> ... <cpu match="MATCH"> <model>NAME</model> <topology sockets="S" cores="C" threads="T"/> <feature policy="POLICY" name="NAME"/> </cpu> </domain> Where MATCH can be one of: - 'minimum' specified CPU is the minimum requested CPU - 'exact' disable all additional features provided by host CPU - 'strict' fail if host CPU doesn't exactly match POLICY can be one of: - 'force' turn on the feature, even if host doesn't have it - 'require' fail if host doesn't have the feature - 'optional' match host - 'disable' turn off the feature, even if host has it - 'forbid' fail if host has the feature 'force' and 'disable' policies turn on/off the feature regardless of its availability on host. 'force' is unlikely to be used but its there for completeness since Xen and VMWare allow it. 'require' and 'forbid' policies prevent a guest from being started on a host which doesn't/does have the feature. 'forbid' is for cases where you disable the feature but a guest may still try to access it anyway and you don't want it to succeed. 'optional' policy sets the feature according to its availability on host. When a guest is booted on a host that has the feature and then migrated to another host, the policy changes to 'require' as we can't take the feature away from a running guest. Default policy for features provided by host CPU but not specified in domain configuration is set using match attribute of cpu tag. If 'minimum' match is requested, additional features will be treated as if they were specified with 'optional' policy. 'exact' match implies 'disable' policy and 'strict' match stands for 'forbid' policy. * docs/schemas/capability.rng docs/schemas/domain.rng: extend the RelaxNG schemas to add CPU flags support

GNUTLS uses gcrypt for its crypto functions. gcrypt requires that the app/library initializes threading before using it. We don't want to force apps using libvirt to know about gcrypt, so we make virInitialize init threading on their behalf. This location also ensures libvirtd has initialized it correctly. This initialization is required even if libvirt itself were only using one thread, since another non-libvirt library (eg GTK-VNC) could also be using gcrypt from another thread * src/libvirt.c: Register thread functions for gcrypt * configure.in: Add -lgcrypt to linker flags

The virFileResolveLink utility function relied on the POSIX guarantee that stat.st_size of a symlink is the length of the value. However, on some types of file systems, it is invalid, so do not rely on it. Use gnulib's areadlink module instead. * bootstrap (modules): Add areadlink. * src/util/util.c: Include "areadlink.h". Let areadlink perform the readlink and malloc. * configure.in (AC_CHECK_FUNCS): Remove readlink. No need, since it's presence is guaranteed by gnulib.

Commit 66137344 changed the Python detection mechanism in configure to use AM_PATH_PYTHON. This results in a changed install location for the Python bindings, at least on Fedora 12 64bit systems. Before this commit libvirt.py and libvirtmod.so were installed to /usr/lib64/python2.6/site-packages After this commit they are installed to /usr/lib/python2.6/site-packages Mixed Python packages (containing *.py and *.so files) should be installed to the pyexecdir directory detected by AM_PATH_PYTHON. This restores the install location from before the AM_PATH_PYTHON commit. * configure.in: remove unnecessary pythondir export * python/Makefile.am: switch from pythondir to pyexecdir

This patch fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=509306 The bug reporter says that vol-delete does not support the --pool option, but that's not the case in the current head.
