Qemu aarch64 emulation question

[David Faller]

Dear all,

 

I have a little question about aarch64 virtualization on x86_host.

At home I build up a virtual machine running aarch64 debian.
My system setup is an AMD Ryzen 5900x.
On this System aarch64 emulation runs really smooth and fine without high cpu usage.

So after I finished my project and moved this VM to our cluster in our company, the the vm is running big slowly and has a high cpu usage.
The servers there uses 2  CPU E5-2683 v4.

 

So my big question here is, is there a supported list of cpus where I could determinate if an virtual aarch64 vm will run smoothly ?

 

Or a list of cpu feature flags when we would like to emulate aarch64?

 

best Regards and many thanks,
