Hi,

I am running HB in a Windows 10 Virtual Machine (KVM) provided by unRAID.

I've noticed that whenever HB is running my unRAID log is full of:-

ov 3 12:01:14 Tower kernel: kvm [8047]: vcpu0 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop
Nov 3 12:01:14 Tower kernel: kvm [8047]: vcpu0 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop

Nov 3 12:01:15 Tower kernel: kvm [8047]: vcpu0 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop

When I shutdown HB the messages end.

I realise this may not be a HB issue but any ideas what HB is doing that could cause these messages?

Thanks.

Here's a reference that says:

I've noticed similar messages starting Windows VMs, even ones that work just fine and researched this well over a year ago.
My understanding is that these errors happen because Windows is probing the CPU to see if certain instructions/registers exist so it knows what features are available.
When it probes something that is not available those unhandled wrmsr/rdmsr errors get thrown from KVM.
So in most cases these errors mean nothing.

Hi Scott,

Yes everything still works fine would just be good to get rid of these messages.

Just to reiterate, this is specifically related to HB, only when I run HB do I see these messages.

I run lots of other applications like Mezzmo, BubbleUPnP etc on this system and they all run fine with no messages - its HB that causes them.

Thanks.

I agree that HB must be doing something to cause it then. If I could find what that error message is referring to, I might be able to offer a guess. Not sure where to start.

OK no problem, just thought it was worth an ask.

I can easily live with it.
