Marcelo,
The behavior on reset is to return the TSC_AJUST msr value to 0x0. I am
currently initializing this emulated msr in kvm_arch_vcpu_init().
- Behaviour on reset: what is the behaviour on RESET?
I am testing the rebase now. I would like to get any needed changes for this
initialization

Reset is handled by QEMU. kvm_arch_vcpu_init is only called during vcpu
Marcelo,
My latest QEMU patch ([PATCH V5] target-i386: Enabling IA32_TSC_ADJUST for QEMU
KVM guest VMs) seems to be OK with regards to reset. The tsc_adjust variable is
being zeroed by the memset() in x86_cpu_reset(). Later code seems to write
these values through kvm_put_msr() by way of

CPUID.7.0.EBX[1]=1 indicates IA32_TSC_ADJUST MSR 0x3b is supported
Basic design is to emulate the MSR by allowing reads and writes to a guest
vcpu specific location to store the value of the emulated MSR while adding
the value to the vmcs tsc_offset. In this way the IA32_TSC_ADJUST value will

Thanks Marcelo,
I'll address these items.
- Please rebase against queue branch on kvm.git.
I am not sure how to do this. The repository I have been working against is:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
I assume that I need to change this in some way but I am
