@ashwanth-07
From following log, vm0 assigns invalid PCPU.

sanitize_vm_config: vm0 assigns invalid PCPU (affinity: 0x000000000000000f)
VM configuration check fail!

You are using v3.0 branch, correct?
Please share your board.xml and scenario.xml.
Thanks!

please do help

fuzhongl · 2022-08-08T01:43:22Z

@ashwanth-07 The format isn't correct after paste.
Could you please upload your board.xml as file; instead of paste it.
Following is example for your scenario.xml(rename it to .txt)
github.txt
You shared scenario.xml works well with my board:

ACRN Configuration Summary:
Build directory: /home/acrn/acrn-hypervisor/build/hypervisor
This build directory is configured with the settings below.
- BOARD = whl-ipc-i5
- SCENARIO = github
- RELEASE = y

Thanks!

ashwanth-07 · 2022-08-08T05:10:52Z

@fuzhongl Thanks for responding, I have attached the files like you asked, please do help.

my_board.txt
scenario.txt

fuzhongl · 2022-08-08T06:54:58Z

@ashwanth-07 The issue is root caused: cpu_id info doesn't match in board.xml.

Vs

Please help to workaround it with following modification:
From

  <CPU_PROCESSOR_INFO>
	0, 1, 2, 3
	</CPU_PROCESSOR_INFO>

To

  <CPU_PROCESSOR_INFO>
	0, 1
	</CPU_PROCESSOR_INFO>

Will provide the final fix later.
Thanks!

ashwanth-07 · 2022-08-08T09:03:18Z

@fuzhongl thank you ! It worked, please do send the final fix later

Do you use v3.0 codebase or master codebase?
Any error log during generate board.xml on your side? Could you please re-generate the board.xml with v3.0?
Thanks!

ashwanth-07 · 2022-08-10T10:19:40Z

@fuzhongl thanks for responding , I did get this warning while generating board.xml

ashwanth-07 · 2022-08-10T10:20:01Z

and yes I am using v3.0

fuzhongl · 2022-08-11T23:48:40Z

@fuzhongl thanks for responding , I did get this warning while generating board.xml

@ashwanth-07 Could you please share the following log on native? which is used to generate the board.xml.

lscpu

Following are the example of my side:

ashwanth-07 · 2022-08-12T14:07:53Z

@fuzhongl thanks for responding, here are the logs for the commands you gave

fuzhongl · 2022-08-12T14:22:28Z

@ashwanth-07 There are only 2 CPU on your board.
You don't enable Hyper-Thread when generate the board.xml, right?
If yes, we need to check why board inspector try to bring up core 2 and 3.

Following is the log from my side:

acrn@acrn-OptiPlex-9010:~$ lscpu |grep "CPU(s)"
CPU(s):              4
On-line CPU(s) list: 0-3
acrn@acrn-OptiPlex-9010:~$ cat /proc/cpuinfo |grep processor
processor       : 0
processor       : 1
processor       : 2
processor       : 3

ashwanth-07 · 2022-08-15T03:21:35Z

@fuzhongl thanks for responding and sorry for the delay,
Yes I only have 2 cpus

ashwanth-07 · 2022-08-15T03:22:59Z

I dont think I enabled hyperthreading, these are all the commands that I ran to create board.xml

ashwanth-07 · 2022-08-15T03:29:36Z

@fuzhongl I have enabled intel virtualization in BIOS, it couldn't be a problem, could it?

fuzhongl · 2022-08-15T03:35:01Z

@fuzhongl I have enabled intel virtualization in BIOS, it couldn't be a problem, could it?

@ashwanth-07 You are right, VMx and VTd should be enabled in BIOS.

ashwanth-07 · 2022-08-22T04:15:44Z

@fuzhongl ,thanks for responding...I only have a VT-X setting in my bios. I dont have a VMx or a VTd, could you please help

fuzhongl · 2022-08-25T06:57:46Z

@ashwanth-07 Could you please help to share following info?

cat /sys/devices/system/cpu/offline
cat /sys/devices/system/cpu/possible

Thanks!

fuzhongl · 2022-09-28T05:56:33Z

Close it since the issue can't be reproduced on my side; and no feedback long time.
