I am using https://github.com/kholia/OSX-KVM to run both Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina and Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave in qemu, and it works. But I also have one mac that still runs El Capitan, so I wanted to be able to run El Capitan in qemu too -- it's not working though, it always hangs at the ++++++++++++++++++++++++++++++++ after booting the BaseSystem with -v.
The BaseSystem was extracted from the El Captian installer, of which one can download a recently signed version here (Older El Capitan installers might have an expired certificate):

I wasn't able to enable -v boots with OpenCore, only with Clover. So in clover -v looks like this:

As far as I have been able to figure out, if the boot stops there it's either a problem related to ignore_msrs or aptiofix.
I wanted to use aptiofix with clover but https://github.com/acidanthera/AptioFixPkg/releases says it's already part of OpenCore -- but OpenCore is not working for me either, or maybe I need to configure aptiofix...
This is how I start qemu for El Capitan:
