Introduce Virtualization and Kernel Infrastructure to Newbies - Xiao MiaoMiao & Ben Shushu
Virtualization is the infrastructure for the Cloud and Linux Kernel is largely used in the enterprises, they are so important, however, they become more and more complex that are not easy for the newbies to reach the gate to getting into these fields. Linux kernel is deployed in many areas, like mobile phone, embedded system, cloud server, IoT and so on. Linux kernel is developed rapidly by community, and its code is more than 20 million lines. It is very difficult for system administrators and beginners to study it. We are the experienced developers working On Qemu/KVM/Kernel in the open source community for more than 5 years, we will share our experience to help newbies to quickly get the whole picture of virtualization/kernel and bring them to the open source community.

And
also
I'm
going
to
introduce
this
topic
together
with
Shomi
I'm.
You
know
it
may
need
some
basic
knowledge
about
Linux
and
on
our
another
speech
of
us,
we
have
introduced
Kate
them
and
also
they
haven't
listened
to
us
on
k2m
and
they
asked
us
I,
don't
understand,
Kate
X,
I'm,
working
on
cabinets
and
working
on
doukas,
so
I
don't
understand
what
what
they
talk
about.
A
A
I
think
we
should
first
consider
several
questions
why
we
need
an
operation
systems
when
we
are
sending
messages
on
our
phones.
We
are
listening
to
music
at
the
same
time,
maybe
looking
at
information
about
the
stock
markets.
If
we
don't
have
any
of
the
operation
systems
of
a
OS,
then
we
know
that
there
are
different
kind
of
processes.
You
need
to
switch
between
different
process
because
they
is
not
going
to
run
a
back-end
and
without
this
motif.
A
A
Of
this
OS
I
think
for
the
newbies
of
this
field.
You
need
to
consider
the
following
questions.
Maybe
you
have
learned
about
OS
in
your
universities?
Maybe
you
will
recite
some
of
the
concepts
about
our
definition
of
some
terms,
but
have
you
ever
think
about
what
kind
of
content
or
what
kind
of
objects
that
they
OSS,
managing
or
administrating
well
get
back
to
of
our
Help
Center
go
when
the
computer
was
just
owned,
and
at
that
time
the
audience
is
developing
together
with
hardware.
And
what
is
this?
A
It
would
be
quite
helpful
if
you
think
from
this
perspective.
Next,
what's
the
relationship
between
Linux
and
Linux
system
and
the
Linux
kernel,
it
may
have
something
which
is
two
concepts
and
also
you
can
also
consider
what
kind
of
design
concepts
that
the
Linux
kernel
can
adopt.
We
know
that
there
were
different
kind
of
kernels
and,
for
example,
Windows
kernel,
apples,
kernel
and
also
Google
also
has
a
mic.
We
can
know
of
good
of
Google's,
and
also
other
companies
will
have
their
own
chaos
as
well.
A
A
A
Actually,
there
is
a
decade,
for
example,
on
our
form.
We
are
running
different
type
of
light
of
redhead
and
also
the
different
applications
running
on
Bennigsen.
Even
the
fundamental
framework
of
it
is
running
on
the
Linux
in
recent
years.
Originally
it's
a
little
bit
cool
in
this
industry,
but
because
of
that
trade
war
between
the
two
countries-
and
this
topic
has
been
popular
again
because
we
don't
have
a
self
developed
OS
in
China.
If
we
design
a
new
focus,
what
should
we
do?
What
is
the
most
difficult
things
we
should
overcome.
A
B
B
B
B
B
Linux
is
like
a
a
graduated
students
amateur
product
and
he
prefers
macro
design
with
simple
designs
and
superior
performance,
but
other
theories.
They
must
be
put
into
industrial
practice
and
that's
how
a
compromise
was
achieved
and,
of
course,
a
Linux
kernel
have
fused,
with
the
advantages
of
our
both
micro
and
macro.
A
A
A
A
B
It
can
automatically
load,
hardware,
drive
drivers
and
for
some
of
the
gate,
drivers
they
can
be
dynamically
loaded
and
above
it
is
our
user
space.
In
in
the
user
space
you
can
see,
there
is
a
very
important
layer,
quarter
system,
schedule,
scheduling,
layer,
so
all
the
apps
and
programs
they
will
use
utilize
the
scheduler
layer
to
visitor
the
kernel
resources.
A
A
B
A
B
Using
Java,
but
for
some
traditional
stuff,
including
eggs,
window
and
cutie,
Bank
and
TT
Bank,
some
graphic
interfaces
through
cutie
and
gtk
database
and
then
through
Lipsy
and
then
to
the
user
space
and
to
the
system
scheduler
between
user
space
and
the
kernel
space
and,
of
course,
virtual
VM
is
also
very
quite
popular
for
VM.
It
can
access
to
say
language
layer,
but
also
Linux
kernel
like
a
link,
space,
etc.
B
A
A
B
As
an
overview
of
Linux
architecture,
an
illustration
of
a
scheduler,
it
supports
different
types
of
sessions
like
session
management,
etc,
are
not
going
to
details
for
a
second
time,
and
internal
memory.
Management
is
also
a
big
component.
Yesterday
we
talked
about
case
am
new
Numa
and
parents.
They
are
all
related
to
internal
memory,
because
internal
memory
management
is
a
very
complicated
in
different
sessions.
So
this
is
and
also
it
includes
the
interruption
management
and
for
Linux
kind
of
why
it's
so
popular.
A
B
A
B
B
A
B
A
B
A
A
A
A
A
A
B
A
B
A
A
B
A
A
B
It
starts
with
the
creation
of
at
the
end.
We
can
compare
this
as
a
preparing
boxes
and
with
the
Box
you
can
inject
as
memories.
We
can
register
the
memories,
so
it's
comparable
to
injecting
the
memory
to
to
the
machine
and
after
the
registration
you
can
create
a
corresponding
BIOS
and
initiate
the
boosting
environment,
and
then
you
can
run
a
CPU
just
like
inserting
the
CPU
to
to
the
server.
And
after
that
you
can
run
the
VM
and
run.
A
A
B
A
A
A
A
B
Maya
mentioned
it
provides
a
up
interfaces
through
a
particular
file
commanding
file.
You
only
need
to
open
the
file
and
do
outcome,
control
and
I'll
control.
The
name
is
creator,
kvn,
great
VM
and
after
the
command
it
will
feed
back
the
file
description
and
this
description
kind
of
stand
it
as
opinion,
and
if
you
were
to
run
the
VM
you
you
must
operate
it
from
the
fire
and
about
the
termination,
the
BNF
de
you
can
close
it
and
then
the
Bayon
module
resources
will
be
suspended.
A
A
A
B
A
B
B
A
B
B
A
B
A
Memory
is
very
complicated,
so
I
just
demonstrate
the
visits
route
and
also
how
the
cubm
to
process
it
when
its
ensure
initialize
the
memory
is
not
allocated
to
any
anywhere.
So
there
is
no
resources
to
it.
When
they
the
memory
SS
anything,
then
the
CPU
will
switch
from
the
memory
to
the
host
because
of.
A
B
A
A
Do
not
match
the
physical
location
of
this
memory
to
register
at
the
KVM
and
then
they
will
take
it
as
a
mo
ISS
that
is
MMI
OSS.
It
means
it's
from
the
equipped
equipments.
Then
it's
going
to
start
equipment
visit
equipment
access,
then,
based
on
this
understanding,
they're
going
to
try
to
match
this
location
to
the
to
the
interface
of
the
increment.
Instead,
man
X
is
the
V
CPU.
B
A
The
CPU
its
use
is
the
threats
use
on
and
as
a
host.
So
when
the
KB
I
am
creating
the
VC
at
the
the
CPU,
then
it's
going
to
create
this
threat
and
on
this
threat,
then
it's
going
to
provide
some
interface
telling
KBM
mojo
awesome
run
the
teaser,
give
you
the
TC
qu
and
also
to
run
to
work
loader
provided
by
the
PBM.
B
A
A
For
creating
the
V
CPU
is
called
KBM,
8
v
CPU
and
later
it's
going
to
back,
get
back
to
it
and
close
it.
So
you
need
to
close
and
destroy
the
V
CPU
for
the
destroys
operations
running
this
way.
Cpu
is
a
very
complicated
process,
but
overall
it
has
user
space
and
also
has
the
k
vm
module
to
go
through
the
whole
process.
A
B
A
A
If
the
recipe
you
have
get
access
to
some
of
the
sensitive
resources
for
all
equipments,
they
will
get
into
a
new
mode
that
is
back
to
the
kV
and
module.
So
first
of
all,
Kathy
and
mortar
is
going
to
fix
it
themselves
to
satisfy
this
access
themselves.
If
they
found
that
KVM
--d
do
not
have
sufficient
resources
who
process,
it
then
needs
some
improvement
from
user
space.
They
then
they
are
going
to
schedule
more
resources
to
down
there
cascade
some
of
the
resources
there.
B
B
A
B
A
A
B
B
A
B
A
A
A
Yes,
it's
going
to
have
a
control
called
the
MCS
in
the
V
MCS.
You
are
able
to
defined
it,
capturing
behaviors,
for
example,
what
kind
of
sessions
or
what
sessions
on
what
kind
of
things
that
you
want
to
capture,
so
this
is
implemented
or
performed
by
the
hardware.
Another
question
is
that,
and
we
have
talked
about
the
sequence
virtualization,
and
maybe
it
has
better
performance
than
other
virtualization
and
also
able
to
be
very
aware
by
the
OS
and
but
it
also
needs
some
type
of
support.
A
It
means
all
of
those
windows
or
the
Linux
need
to
support
this
type
West
for
first
question:
no
matter,
is
it
the
first
type
or
the
second
type?
The
OSS
is
not
that
we,
so
the
visibility
of
it
is
not
a
high.
You
can
only
see
their
interface.
The
second
is
that
you
find
now
the
versions
need
to
support
both
of
those
types
before
the
OS
are
established,
and
it's
going
to
build
up
a
CPA
ID
and
then
it's
got.
A
Let's
go
it's
a
sensitive
inter
interface
like
them.
It's
going
to
connect
it
with
it
as
well
and
switch
to
it
and
as
for
this
virtualization,
usually
it's
based
on
the
same
hardware
structure
and
then
to
plug
it
into
our
equipment.
For
some,
however,
sometimes
I
want
to
run
or
mimic
or
run
to
arm
the
equipment.
Is
it
possible
with
the
current.
