0x1AD support is available for all
latest desktop/mobile platform except some XEON processors. I
guess you did not enable msr module by "modprobe msr" command.
I stated the requirement in README file
Release: Ubuntu 18.04+ or ClearLinux 30210+
Tools: cpuid, rdmsr, lspci, dmidecode
kernel cmdline: "idle=nomwait intel_idle.max_cstate=0
please make sure these tools is working
before you execute board parser tool and vt-d is enabled in BIOS.
ACRN does not work well on some Xeon processor because the main
purpose of ACRN is for IoT market, but we are still trying to fix
some issues occurs on server platform.
With current code, we have below limitations but we will fix them
1. memory <= 16G
3. intel speedstep is enabled
3. ACPI CPU Pstate/Cstate table are
enabled, and no mwait support when enforce ACPI idle driver.
please let me know your progress.

Tried running board_parser.py from inside
18.04.3 on the same machine and getting the below error ...
sudo python3 misc/acrn-config/target/board_parser.py
rdmsr: open: No such file or directory
0x1ad not support in this platform!
I understand that a certain MSR is NOT present in my CPU.
Is that the end of road for ACRN on this machine ?
Where can I find information on why ACRN places such h/w
constraints compared to other Type-1 hypervisors (Xen etc)?
Again, looking forward to your reply.
Your machine is fine.
Please replace your /usr/bin/cpuid to a higher version.

Need CPUID version >= 20170122
FYI, PFA o/p of cat
Is there a way I can run ACRN
on this or need to give up on this machine ?
Any help/direction would be
I think it should be OK.
Please refer "Board and VM configuration
workflow" section in
to setup configuration for your board.
Any problems, please let me know.

I have a Core-i7(6500U) based laptop
which supports h/w virtualization.
Wondering if ACRN can run on that or
has any technical restrictions in running
on platforms other than the ones in the
supported h/w list ?
Any would help to get started on ACRN
would be appreciated.
