Xvisor hangs when RVV is enabled

Here is my config:

My command:

./build/riscv64-nemu-interpreter -b /ci/test-home/xvisor

Additional infomation:

Difftest against spike doesn't report error. So this is possibly related to device, interrupt, or exception.
During booting, printing line [guest0/uart0] [ 11.422723] Freeing initrd memory: 16384K cost much more time than that with RVV disabled : 11.42 VS. 2.x
