Error Starting Domain when I launch Hackintosh VM

I am new to Hackintosh, and I got all the files necessary, create a Virtual Machine in Virt-manager,made all the changes to the XML files necessary to point to the VARS and CODE files, and when I try to launch the virtual machine I get:

Error starting domain: operation failed: unable to find any master var store for loader: /home/Hackintosh-KVM/OVMF_CODE.fd.

Does anyone know what this error is?
