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.
3. type vm.list and find the VM
VM name VM UUID
4. type vm.update <vm_name>extra_flags="enable_hyperv_clock=False"
_ <acropolis>vm.update pfSense extra_flags="enable_hyperv_clock=False"
5. power on the VM
Now it just work. at least for me.</vm_name>
