When I try to create a root config for my Ubuntu 18.04 Intel x86 machine, I get 
the following error:

hintron@bazooka:~/code/jailhouse$ sudo jailhouse config create bazooka.c
Traceback (most recent call last):
  File "/usr/local/sbin/jailhouse-config-create", line 1185, in <module>
    dmar_regions)
  File "/usr/local/sbin/jailhouse-config-create", line 762, in parse_dmar
    f = input_open('/sys/firmware/acpi/tables/DMAR', 'rb')
  File "/usr/local/sbin/jailhouse-config-create", line 160, in input_open
    raise e
IOError: [Errno 2] No such file or directory: '//sys/firmware/acpi/tables/DMAR'

Any ideas as to what am I doing wrong? Why would /sys/firmware/acpi/tables/DMAR 
be missing?

Thanks,
Michael
