PfSense 2.3 on Nutanix CE

  • 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>
