 on my core ultra 125h i got this starting an nvmm guest:
 
 panic: kernel diagnostic assertion "(xcr0 & ~__BITS(XSAVE_MAX_COMPONENT, 0=
 )) =3D=3D 0" failed: file "/usr/src3/sys/dev/nvmm/x86/nvmm_x86.c", line 47=
 6
 
 it does not matter if i restrict it to run on only the p-cores,
 or only on the e-cores (this CPU has 4 p-cores, 8 e-cores, and
 2 le-cores.)
