Subject: KVM: SVM: always set MSR_AMD64_TSC_RATIO to default value
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3e4546d5bd38a1e98d4bd2de48631abf0398a3a2;p=qemu.git

KVM: SVM: always set MSR_AMD64_TSC_RATIO to default value

Even when the feature is not supported in guest CPUID,
still set the msr to the default value which will
be the only value KVM will accept in this case
