PfSense 2.3 on Nutanix CE

[Ntandrup]

I have had a few problems with getting pfSense to run on Nutanix Community Edition (AHV).

When i started i had this problem
–---------------------
Timercounter "TSC-low" frequency 1646220606 Hz quality 800
Timercounter "Hyper-V" frequency 10000000 Hz quality 10000000
Event timer "HyperV" frequency 10000000 Hz quality 1000
kernel trap 9 with interrupts disabled

Fatal trap 9: general protection fault while in kernel mode
cpuid - 0; apic id - 00

As you can see it also shows a Hyper-V Timecounter error. This timecounter is the real problem so here is how to solve it.
the solution comes from Nutanix KB3258

In AHV the Hyper-V clock is enabled by default. so here is how to disable it.
1. power off the VM
2. Log into any Controller VM and access acli.
        nutanix@cvm$ acli
3. type vm.list and find the VM
_        <acropolis>vm.list
        VM name      VM UUID
        pfSense      xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx</acropolis>_
4. type vm.update <vm_name>extra_flags="enable_hyperv_clock=False"
_          <acropolis>vm.update pfSense extra_flags="enable_hyperv_clock=False"
          pfSense: complete</acropolis>_
5. power on the VM

Now it just work. at least for me.</vm_name>
