I was already writing here that it doesn’t work actually
What I did to set it off definitely, was to add it to u grub line
GRUB_CMDLINE_XEN_DEFAULT="console=none dom0_mem=min:1024M dom0_mem=max:1536M ucode=scan smt=off gnttab_max_frames=2048
Obviously, you would want to set it on instead and try it.
