This test case has the same tests as tests/virtio-blk-test.c except for
tests have block_resize. Since vhost-user server can only server one
client one time, two instances of qemu-storage-daemon are launched
for the hotplug test.
In order to not block scripts/tap-driver.pl, vhost-user-blk-server will
send "quit" command to qemu-storage-daemon's QMP monitor. So a function
is added to libqtest.c to establish socket connection with socket
server.

This test case fails for me:
qemu-system-x86_64: Failed to read from slave.
qemu-system-x86_64: Failed to set msg fds.
qemu-system-x86_64: vhost VQ 0 ring restore failed: -1: Success (0)

qemu-system-x86_64: Failed to read msg header. Read -1 instead of 12. Original

qemu-system-x86_64: vhost VQ 0 ring restore failed: -1: Input/output error (5)
Does "make -j4 check" pass for you?
Actually it's a success since it won't fail CI. The reason for the
occurrence of these dubious messages is after finishing the tests,
vhost-user-blk-server is stopped before qemu-system-x86_64 is destroyed.
I'll see if I can find a way to kill qemu-system-x86_64 first.
