vHost has a parameter called base_name. Temporarily you could specify --bas=
e-name as
the unix domain socket path, and set it in the qemu command line as socket =
path.
recommended qemu command line for memory and vhost configuration:
-m $MEM -object memory-backend-file,id=3Dmem,size=3D${MEM}M,mem-path=3D/mnt=
/huge,share=3Don -numa node,memdev=3Dmem  -mem-prealloc
-chardev socket,id=3Dchar0,path=3D$sock_path  -netdev type=3Dvhost-user,id=
=3Dmynet1,chardev=3Dchar0,vhostforce \
-device virtio-net-pci,mac=3D52:54:00:12:34:11,netdev=3Dmynet1
