I've adjusted the file "sysfs_parser.py" and commented out line 754.
This means that the "has_extended_caps" tag is not set to "True".
Now I get the following messages:
Feature Availability

Number of CPUs > 1 ok
Long mode ok
Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory:
'//sys/firmware/acpi/tables/DMAR'
The directory "/sys/firmware/acpi/tables/DMAR" does not actually exist on
my system!
There are only the following directories:

Remarks:
- my system has an "Intel BayTrail SoC" wih 2 cores
- I've added "intel_iommu=off" to the kernel command line
- "dmesg | grep DMAR" brings no result
- option "Intel Virtualization Technology" is enabled in the BIOS
- "cat /proc/cpuinfo | grep vmx" or "grep --color vmx /proc/cpuinfo" brings
that "vmx" is in the "flags"
- "lscpu" brings "Virtualization: VT-x"
What should I do?
