After realizing the inconsistency on VT-x emulation in VMware and switching to
VBox, I get the following error in hardware check command:
mjonian@mjonian-VirtualBox:~/Projects/jailhouse/tools$ sudo jailhouse hardware
check
Feature Availability
------------------------------ ------------------
Number of CPUs > 1 ok
Long mode ok
Traceback (most recent call last):
File "./jailhouse-hardware-check", line 147, in <module>
iommu, _ = sysfs_parser.parse_dmar(pci_devices, ioapics, dmar_regions)
File "/home/mjonian/Projects/jailhouse/tools/../pyjailhouse/sysfs_parser.py",
line 338, in parse_dmar
f = input_open('/sys/firmware/acpi/tables/DMAR', 'rb')
File "/home/mjonian/Projects/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'
I've checked that VT-x is enabled in bios and I've run the VM with the
intel_iommu=off kernel parameter. To get you out of doubt, I've installed
Ubuntu v20.04 with kernel 5.4.77 natively in a machine and checked all the
previous. The same result when trying to check the hardware... Any ideas?
