This patch drops the notify used by mevent_add/del and
call epoll_ctl to add/delete target fd. Only keeps
global_head to track mevent added and makes the code
logic in mevent_dispatch() a littel bit simpler.
Another thing is related with epoll_ctl. If the target
fd is regular fd which doesn't support epoll, epoll_ctl
will return -1. When DM is start by systemd, the STDIO
is not mapped to terminal, epoll_ctl on STDIO could

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

acrnlog is an SOS userland tool to capture ACRN hypervisor log
to /tmp/acrnog/. Two kinds of logs would be saved:
- log of current running;
- log of last running if crashed and logs remaining.
[Usage] acrnlog [-s] [size] [-n] [number]
[Options]
-h: print this message
-s: size limitation for each log file, in MB.
0 means no limitation.
-n: how many files you would like to keep on disk

Script usage:
[Usage] acrnalyze.py [options] [value] ...
[options]
-h: print this message
-i, --ifile=[string]: input file
-o, --ofile=[string]: output file
--vm_exit: to generate vm_exit report
Note: bash and python2 are required.
Example:
Assumed trace data have been copied to /home/xxxx/trace_data/20171115-101605
# acrnalyze.py -i /home/xxxx/trace_data/20171115-101605/0 -o /home/xxxx/trac
e_data/20171115-101605/cpu0 --vm_exit
- "--vm_exit" specify the analysis to do, currently, only vm_exit analysis
is supported.
- A preprocess would be taken out to make the trace data start and end with
an VM_ENTER, and a copy of original data file is saved with suffix ".orig";
- Analysis report would be given on the std output and in a csv file with
name specified via "-o outpu_file";

acrntrace: is an debug tool running on SOS to capture trace data.
Usage:
1) Start tracing
Capture buffered trace data:
# acrntrace
or clear buffer before tracing start:
# acrntrace -c
A folder will be created to save the trace data files are under
/tmp/acrntrace/, named with time string.
Eg: /tmp/acrntrace/20171115-101605
2) Stop tracing

There are two things here:
1. Enable basic vsbl boot functionality.
2. add long option to DM to specific vsbl file. So DM could
choice to boot guest with vsbl.
It's hard to find a suitable short option. So only long option
is supported for vsbl file name option.
If long option "--vsbl='vsbl_file_name'" is given in DM
commandline, the "vsbl_file_name" will be loaded by DM
first and running. vsbl will be response to lead guest to
next boot stage.

Some virtio PCI devices can change the device configuration state, as
reflected in the device-specific configuration region of the device. In
this case:
* If MSI-X capability is disabled:
1. Set the second lower bit of the ISR Status field for the device
2. Send the appropriate PCI interrupt for the device.
* If MSI-X capability is enabled:
1. If config_msix_vector is not NO_VECTOR, request the appropriate
MSI-X interrupt message for the device, config_msix_vector sets
the MSI-X Table entry number.
A single interrupt MAY indicate both that one or more virtqueue has been
used and that the configuration space has changed.

Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.
