Processor Intel(R) Xeon(R) CPU E5-2630 0 | bhyve

I need to check if my processor support bhyve.

Code: 
root@jail-host:~ # grep -i cpu /var/run/dmesg.boot
CPU: Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz (2294.53-MHz K8-class CPU)
cpu0: <ACPI CPU> on acpi0

Code: 
root@jail-host:~ # grep Features /var/run/dmesg.boot
  Features=0x1783fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE,SSE2,HTT>
  Features2=0x1e98220b<SSE3,PCLMULQDQ,MON,SSSE3,CX16,SSE4.1,SSE4.2,POPCNT,AESNI,XSAVE,OSXSAVE,AVX>
  AMD Features=0x28100800<SYSCALL,NX,RDTSCP,LM>
  AMD Features2=0x1<LAHF>
  Structured Extended Features3=0x10000400<MD_CLEAR,L1DFL>

on the virtual machine I get:
Code: 
root@jail-host:~ # vm init
/usr/local/sbin/vm: ERROR: unable to load vmm.ko!

oot@jail-host:~ # kldstat
Id Refs Address                Size Name
 1   23 0xffffffff80200000  227ad00 kernel
 2    1 0xffffffff8247b000   3bad38 zfs.ko
 3    2 0xffffffff82836000     a448 opensolaris.ko
 4    1 0xffffffff82b19000     2698 intpm.ko
 5    1 0xffffffff82b1c000      b40 smbus.ko
 6    1 0xffffffff82b1d000      acf mac_ntpd.ko
 7    1 0xffffffff82b1e000   537420 vmm.ko

but I'm almost sure it's impossible to check it on VM.

How can I do it ?

Yes,
Inter(R) VT-d is enabled.

Bhyve doesn't support specific processors, it requires certain features. If the CPU has those then it's supported.

what's the output of dmesg | grep -i vt-x? do you see EPT there?

My host machine is on debian:
I read this thread:

How to detect if VT-X has been turned on in the BIOS?

I know I can check is VT-X is supported by a processor by egrep '(vmx|svm)' /proc/cpuinfo. But even if it's supported, it can be turned off in the BIOS. How can I detect if it's turned on or off?

Code: 
admin@host:~$ sudo modprobe msr
admin@host:~$ sudo rdmsr 0x3A
5

Code: 
admin@host:~$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

It's looks ok I think.
