Petelinux installation in Virtual Machine

Linux systems are installed in disk partitions, not directories. You can setup a multi boot system using a linux boot manager.

The system already has Linux operating system. The question is how necessary is to install Petalinux in Virtual Machine ?

If I install Virtual Machine and then Petalinux then only a part of the CPU cores and RAM will be assigned to run Virtual Machine this will slow down performance.

Yes, if you need maximal performance, you want a multi-boot installation.

HI, I am sure if I fully understand the meaning of multi-boot installation. Can you please explain ? My main question is which approach is better performance wise ? Either to install Petalinux directly on Ubuntu LTS 18.04 or first install Oracle Virtual Machine and then install Petalinux ? Petalinux is upported by Xilinx for ZYNQ 7000.

I was under the assumption that you want to keep the standard Linux installation and use Petalinux specifically for FPGA development. I presume performance is critical, because FPGA compilation time of complex designs is always too long. Thus I suggested a native Linux installation instead of a virtual machine. It would be setup as multi boot with the standard Linux started by default. You'll find sufficient instructions how to do.

You can however maximize the performance of a virtual machine by assigning most of the available RAM and CPU cores. It may be that the difference to a native Linux installation that owns 100% of the computer resources isn't so big, you can try.

There's a lot of discussions about VM performance, also about pro and con of Vivado on VM. Don't want to retell it.

Regarding VM performance in general, they seem to confirm what I presumed above. The VM overhead is small, but you need to assign reserve sufficient resources.

Hi, is it always necessary to install Petalinux in Virtual Machine ? How about to install Petalinux directly on the standard Linux machine ?
