This changes the -cpu check/enforce code to work as it should: it will check every single CPUID bit to make sure it is supported by the host. The changes are a bit intrusive, but: - The longer we take to make "enforce" strict as it should (and make libvirt finally use it), more users will have VMs with migration-unsafe unpredictable guest ABIs. For this reason, I would like to get this into QEMU 1.4. - The changes in this series should affect only users that are already using the "enforce" flag, and I believe whoever is using the "enforce" flag really want the strict behavior introduced by this series. This series is based on Andreas' qom-cpu branch, and depends on the series: Subject: [PATCH 0/2] Disable kvm_mmu_op by default on pc-1.4 Message-Id: <1357311145-16410-1-git-send-email-ehabkost@xxxxxxxxxx> Git tree for reference: git://github.com/ehabkost/qemu-hacks.git cpu-enforce-all.v1 https://github.com/ehabkost/qemu-hacks/tree/cpu-enforce-all.v1 Eduardo Habkost (9): target-i386: kvm: -cpu host: Use GET_SUPPORTED_CPUID for SVM features target-i386: kvm: Enable all supported KVM features for -cpu host target-i386: check/enforce: Fix CPUID leaf numbers on error messages target-i386: check/enforce: Do not ignore "hypervisor" flag target-i386: check/enforce: Check all CPUID.80000001H.EDX bits target-i386: check/enforce: Check SVM flag support as well target-i386: check/enforce: Eliminate check_feat field target-i386: Call kvm_check_features_against_host() only if CONFIG_KVM is set target-i386: check/enforce: Check all feature words target-i386/cpu.c | 73 +++++++++++++++++++++++++++++++++++++++---------------- target-i386/cpu.h | 3 +++ 2 files changed, 55 insertions(+), 21 deletions(-) -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
