This adds the following feature words to the list of flags to be checked by kvm_check_features_against_host(): - cpuid_7_0_ebx_features - ext4_features - kvm_features - svm_features This will ensure the "enforce" flag works as it should: it won't allow QEMU to be started unless every flag that was requested by the user or defined in the CPU model is supported by the host. This patch may cause existing configurations where "enforce" wasn't preventing QEMU from being started to abort QEMU. But that's exactly the point of this patch: if a flag was not supported by the host and QEMU wasn't aborting, it was a bug in the "enforce" code.

Instead of carrying the CPUID leaf/register and feature name array on the model_features_t struct, move that information into feature_word_info so it can be reused by other functions. The goal is to eventually kill model_features_t entirely, but to do that we have to either convert x86_def_t.features to an array or use offsetof() inside FeatureWordInfo (to replace the pointers inside model_features_t). So by now just move most of the model_features_t fields to FeatureWordInfo except for the two pointers to local arguments.

This introduces a FeatureWord enum, FeatureWordInfo struct (with generation information about a feature word), and a FeatureWordArray typedef, and changes add_flagname_to_bitmaps() code and cpu_x86_parse_featurestr() to use the new typedefs instead of separate variables for each feature word. This will help us keep the code at kvm_check_features_against_host(), cpu_x86_parse_featurestr() and add_flagname_to_bitmaps() sane while adding new feature name arrays.

KVM_CAP_PV_MMU capability reporting was removed from the kernel since v2.6.33 (see commit a68a6a7282373), and was completely removed from the kernel since v3.3 (see commit fb92045843). It doesn't make sense to keep it enabled by default, as it would cause unnecessary hassle when using the "enforce" flag. This disables kvm_mmu on all machine-types. With this fix, the possible scenarios when migrating from QEMU <= 1.3 to QEMU 1.4 are: ------------+----------+---------------------------------------------------- src kernel | dst kern.| Result ------------+----------+---------------------------------------------------- >= 2.6.33 | any | kvm_mmu was already disabled and will stay disabled <= 2.6.32 | >= 3.3 | correct live migration is impossible <= 2.6.32 | <= 3.2 | kvm_mmu will be disabled on next guest reboot * ------------+----------+---------------------------------------------------- * If they are running kernel <= 2.6.32 and want kvm_mmu to be kept enabled on guest reboot, they can explicitly add +kvm_mmu to the QEMU command-line. Using 2.6.33 and higher, it is not possible to enable kvm_mmu explicitly anymore.

When the raw-posix aio=thread code was moved from posix-aio-compat.c to block/raw-posix.c, there was an unintended change to the ioctl code. The code used to return the ioctl command, which posix_aio_read() would later morph into a zero. This hack is not necessary anymore, and in fact breaks scsi-generic (which expects a zero return code). Remove it.
