Topics have been merged and my last three posts are older then my first three posts.
Anyway, I got OpenCore to run and BaseSystem to boot like this
qvm-features hvm-mac uefi 1
qvm-block a --persistent hvm-mac dispXXXX:loop0
qvm-block a --persistent hvm-mac dispXXXX:loop1
qvm-start hvm-mac
after making the images available in dispXXXX like this
sudo losetup -f /home/user/git/OpenCore.img
sudo losetup -f /home/user/git/BaseSystem.img
Kudos and Thanks to @tzwcfq who also suggested to create a seperate template like this
which might suite the usecase better, since we have to add a lot more then opencore and the installer medium to get the HVM Hackintosh to work.
Next step is to convert as much args from OpenCore-Boot(-CD).sh
into /etc/qubes/templates/libvirt/xen/by-name/hvm-mac.xml
as possible.
