Dear all,
I am trying to checkout Jailhouse in a virtualbox/debian OS
running linux kernel 4.19, x86, it installed successfully i.e. make and
make install were successful.
However when I try running $ jailhouse hardware check I get this error
message:
root@debian:/home/prashant# ./jailhouse/tools/jailhouse hardware check
Feature Availability
------------------------------ ------------------
Number of CPUs > 1 ok
Long mode ok
Traceback (most recent call last):
File "./jailhouse/tools/jailhouse-hardware-check", line 147, in <module>
iommu, _ = sysfs_parser.parse_dmar(pci_devices, ioapics, dmar_regions)
File "/home/prashant/jailhouse/tools/../pyjailhouse/sysfs_parser.py",
line 338, in parse_dmar
f = input_open('/sys/firmware/acpi/tables/DMAR', 'rb')
File "/home/prashant/jailhouse/tools/../pyjailhouse/sysfs_parser.py",
line 90, in input_open
raise e
IOError: [Errno 2] No such file or directory:
'//sys/firmware/acpi/tables/DMAR'
could anyone pin out the problem thanks.
