examples: Running a Linux guest VM and Running multiple Linux guest VMs My obj is :Running a Linux guest not VM my select platform NXP/Freescale Layerscape how to compile

icedieler commented 3 years ago

Hi, I am understanding that you want to run a Linux guest with L4Re on the NXP Layerscape platform. Could you elaborate what your understanding of "Linux guest" is? Because I do not understand how this is different from running Linux in a VM. What is your problem with compiling? Have you followed our tutorial already? Thanks and regards, Matthias.

l4Re hypevisor /service

qemu on the linux

I mean that the L4re up the Hardware,linux geust on l4rE service

what is linux vm based on?

Hi, it is still hard to get a clear picture. Maybe you can describe what your goal is, what you have tried to achieve it and what your current problem is.

qemu on the linux

For that you have to choose the 'arm-virt' platform instead of Layerscape. Please work through our tutorial.

I mean that the L4re up the Hardware,linux geust on l4rE service

That is covered by our tutorial. Please follow it through.

What do you mean?

Hi, Thanks for your reply.

L4re up the hardware,linux guest on l4re service.

I follow the Running a Linux guest VM,but i have a question.

print: BOOTFS: [8118e000-8123c9c0] [C:107000] uvmm BOOTFS: [8123d000-81259e00] [C:109000] l4re BOOTFS: [8125a000-812d51b0] [C:10b000] ned BOOTFS: [812d6000-812d65ea] [C:10d000] virt-arm_virt-64.dtb BOOTFS: [812d8000-812d8dc0] [C:111000] vmm.lua BOOTFS: [812d9000-812d926b] [C:113000] uvmm.ned BOOTFS: [812da000-8386f200] [C:115000] Image.gz BOOTFS: [83870000-83bf0000] [C:117000] ramdisk-arm64.rd MOE: cmdline: moe rom/uvmm.ned MOE: Starting: rom/ned rom/uvmm.ned MOE: loading 'rom/ned' Ned says: Hi World!

I used virt-arm_virt-64.dts . where vbus is set?

Hi,

to understand the general concepts for Hardware pass-through I suggest you follow our Tutorial on Hardware pass-through.

Regards, Matthias.

Hi, Thank you for your reply, I have followed the instructions to solve the above problem . There is a question? The device is 4-core, and the VM is single-core after it is up. Can it be 2-core? 3-core?

I have changed dts.

Best regards,

Hi, I have a question that how to generate ramdisk-armv8-64.cpio.gz ?

Hi,

You can find plenty of tutorials on how to create a ramdisk on the internet. However, the easiest is to extract an existing one, amend it and then to repackage it.

Good luck, Matthias.

Best regards,

Yes. You can have as many virtual CPUs per VM as there are physical ones. First you have to add more CPUs to the device tree (dts). Then you have to extend the scheduler CPU mask in the Lua script. Also make sure you have a SMP build of your guest kernel.

Cheers, Matthias.
