The acrnctl can help user to create, delete, launch and stop UOSs,
To see what it can do, just run:
# acrnctl
or
# acrnctl help
you may see:
support:
list
start
stop
del
add
Use acrnctl [cmd] help for details
There are examples:
(1) add a VM
Each time you can just add one VM. Suppose you have an UOS
launch script, such as launch_UOS.sh
you can run:
# acrnctl add launch_UOS.sh -U 1
vm1-14:59:30 added
Note that, launch script shoud be able to launch ONE UOS. If
it fail, it is better to print some error logs, to tell user
the reason, so that he knows how to solve it.
The vmname is important, the acrnctl searchs VMs by their
names. so duplicated VM names are not allowed. Beside, if the
launch script changes VM name at launch time, acrnctl will
not recgonize it.
(2) delete VMs
# acrnctl del vm1-14:59:30
(3) show VMs
# acrnctl list
vm1-14:59:30 untracked
vm-yocto stop
vm-android stop
(4) start VM
you can start a vm with 'stop' status, each time can start
one VM.
# acrnctl start vm-yocto
(5) stop VM
you can stop VMs, if their status is not 'stop'
# acrnctl stop vm-yocto vm1-14:59:30 vm-android

A monitor component will be added to acrn-dm, which crteats socket,
bind and listening at /run/acrn/vmname. Acrnctl & acrnd could conn
-ect to the socket for communication, using defined message, in
include/monitor_msg.h
For each defined message, a message handler callback could be
registered via monitor_add_msg_handler(). On received of a defined
message, a certain call back will be called. Each callback can only
see the message sender's socket-fd.
When acrn-dm want report something, not triggered by incoming message
it can send broadcast message, use monitor_broadcast().

According to C99:
The empty list in a function declarator that is not part of a definition of
that function specifies that no information about the number or types of the
parameters is supplied.
This means gcc is happy with the following code, which is undesirable.
void foo(); /* declaration with an empty parameter list */
void bar() {
foo(); /* OK */
foo(1); /* OK */
foo(1, 2); /* OK */
}
This patch fixes declarations of functions with empty parameter lists by adding
an unnamed parameter of type void, which is the standard way to specify that a
function has no parameters. The following coccinelle script is used.
