qemu-aarch64 vm over x86 host question

[Emanuel Alkobi]

Hi,

 

I am running the next configuration:

 

Host:

OS:Fedora 34

Qemu vesion: 5.2.0-8.fc34

libvirt version: 7.0.0

architecture:x86_64

kernel version: 5.11.12-300.fc34.x86_64

 

VM:

OS: Ubuntu 20.04 LTS

architecture:aarch64

kernel version : 5.4.0-26-generic

cpu cores:4

cpu model :cortex-a57

Ram: 4Gb

 

 

 

The performance of this configuration is very slow (In compared to a VM with x86 architecture).

I would be happy to know if there are any settings that can be made to improve the performance of this configuration.

 

 

Thanks, Emanuel
