This was part of [PATCH v6 00/16] Allow changing of Hypervisor CPUIDs. Since it is no longer in use by any of the patches in v7, I have split it off. Don Slutz (1): target-i386: Add missing kvm bits. target-i386/cpu.c | 12 ++++++++---- 1 files changed, 8 insertions(+), 4 deletions(-)

Thanks.

Currently "-cpu host,-kvmclock,-kvm_nopiodelay,-kvm_mmu" does not turn off all bits in CPUID 0x40000001 EAX. The missing ones are KVM_FEATURE_STEAL_TIME and KVM_FEATURE_CLOCKSOURCE_STABLE_BIT. This adds the names kvm_steal_time and kvm_clock_stable for these bits.
