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?
Your hardware might be lacking VT-d support, or it is just disabled in the BIOS. Check the latter, and then maybe also check your CPU against ark.intel.com (cat /proc/cpuinfo lists the exact model).
