[Qemu-devel] [PATCH 08/17] target-i386: kvm: Enable all supported KVM features for -cpu host |
Date: |

From: Eduardo Habkost <address@hidden>
When using -cpu host, we don't need to use the kvm_default_features
variable, as the user is explicitly asking QEMU to enable all feature
supported by the host.
This changes the kvm_cpu_fill_host() code to use GET_SUPPORTED_CPUID to
initialize the kvm_features field, so we get all host KVM features
enabled.
This will also allow us to properly check/enforce KVM features inside
kvm_check_features_against_host() later. For example, we will be able to
make this:
$ qemu-system-x86_64 -cpu ...,+kvm_pv_eoi,enforce
refuse to start if kvm_pv_eoi is not supported by the host (after we fix
kvm_check_features_against_host() to check KVM flags as well).
