By the way, how do you compile / run this test? The original commit
message say one should compile it with "make tests/vhost-user-bridge"
but that does not work for me:
$ make tests/vhost-user-bridge
cc tests/vhost-user-bridge.c -o tests/vhost-user-bridge
tests/vhost-user-bridge.c:32:24: fatal error: qemu/osdep.h: No such file
or directory
