[CentOS-devel] Building ARM64 RPMs on AMD64?

Hi,

We are thinking about adding ARM64 based devices to our systems.

As we are using CentOS almost everywhere and have quite a number of
inhouse RPM packages in our company repository, we'd like to enhance it
and add ARM64 alias aarch64 to it.

What I'm still wondering is how to run the build environment for the new
arch?

How does the CentOS project do it, run ARM64 hardware or using emulation?
Or to ask differently, is it an option to run the build system emulated
with QEMU?

Thanks for any insights?
