Thanks, Yuraeitha! It seems xen.cfg is stored in the EFI partition, and I can modify it within dom0 or through Fedora Live without decryption. However I don’t know how to modify it.
I think I should add some parameters in [global] section of xen.cfg, but I fail to find any tips from Xen’s official documents.
