Hello Rajagopal,
I'm not an expert but just a user of ACRN; we've had a similar issue on one of our boards. To enable DMAR table in ACPI, ensure in BIOS settings that IPU is disabled, and VT-d instructions are enabled. If you still have the same error, you'll have to ask your
BIOS provider to add the DMAR table.
Regards,
Dubravko

Yes, DMAR table might not exist if vt-d is disabled in BIOS. BR, Victor

Hello Victor, >>

On our NUC, we have VT-d enabled in VisualBIOS but, there is NO option for IPU. How do we get DMAR tables in this case ? Thanks, Rajagopal

hi Rajagopal, Please try below: disable vt-d in bios, do cold power boot, re-enable vt-d in bios,
do cold power boot again. If DMAR still can not present, you need to contact bios vendor.
Also, please check the result of "virt-host-validate" in native, if DMAR doesn't present, then you also have problem to run KVM/Xen... BR, Victor

Hello Victor,

This has turned out to be the case. Looking at ways to contact VisualBios vendor.
>>Also, please check the result of "virt-host-validate" in native
All checks PASS except the below one
QEMU: Checking for device assignment IOMMU support: WARN (No ACPI DMAR table found, IOMMU either disabled in BIOS or not supported by this hardware platform)
