vhost user virtio gpu cannot work

[????]

hi all,

I'm trying to use vhost user gpu, but the guest(ubuntu 22.04) is very slow, and nearly no response, 

First, i run './vhost-user-gpu -s vgpu.sock -v virgl'

then, i start qemu with

'x86_64-softmmu/qemu-system-x86_64 -enable-kvm -machine pc,memory-backend=mem,accel=kvm -smp 4 -cpu host -drive file=/image/ubuntu-22.qcow,if=virtio -m 4G -device vhost-user-vga,chardev=chr -chardev socket,id=chr,path=contrib/vhost-user-gpu/vgpu.sock -display gtk,gl=on -object memory-backend-memfd,id=mem,size=4G,share=on'

and my qemu version is 6.0.1, and virglrenderer is 0.10.1.

so, where goes wrong?
