||||||
|
<p>To avoid ambiguity about the terms used here here are the definitions for
|
||||||
|
some of the specific concepts used in libvirt documentation:</p>
|
||||||
|
<ul><li>a <strong>node</strong> is a single physical machine</li>
|
||||||
|
<li>an <strong>hypervisor</strong> is a layer of software allowing to
|
||||||
|
virtualize a node in a set of virtual machines with possibly different
|
||||||
|
configurations than the node itself</li>
|
||||||
|
<li>a <strong>domain</strong> is an instance of an operating system running
|
||||||
|
on a virtualized machine provided by the hypervisor</li>
|
||||||
|
</ul><p style="text-align: center"><img alt="Hypervisor and domains running on a node" src="node.gif" /></p>
|
||||||
|
|
||||||
|
<p>Now we can define the goal of libvirt: to provide the lowest possible
|
||||||
|
generic and stable layer to manage domains on a node.</p>
|
||||||
|
|
||||||
|
<p>This implies the following:</p>
|
||||||
|
<ul><li>the API should not be targetted to a single virtualization environment
|
||||||
|
though Xen is the current default, which also means that some very
|
||||||
|
specific capabilities which are not generic enough may not be provided as
|
||||||
|
libvirt APIs</li>
|
||||||
|
<li>the API should allow to do efficiently and cleanly all the operations
|
||||||
|
needed to manage domains on a node</li>
|
||||||
|
<li>the API will not try to provide hight level multi-nodes management
|
||||||
|
features like load balancing, though they could be implemented on top of
|
||||||
|
libvirt</li>
|
||||||
|
<li>stability of the API is a big concern, libvirt should isolate
|
||||||
|
applications from the frequent changes expected at the lower level of the
|
||||||
|
virtualization framework</li>
|
||||||
|
</ul><p>So libvirt should be a building block for higher level management tools
|
||||||
|
and for applications focusing on virtualization of a single node (the only
|
||||||
|
exception being domain migration between node capabilities which may need to
|
||||||
|
be added at the libvirt level). Where possible libvirt should be extendable
|
||||||
|
to be able to provide the same API for remote nodes, however this is not the
|
||||||
|
case at the moment, the code currently handle only local node accesses
|
||||||
|
(extension for remote access support is being worked on, see <a href="bugs.html">the mailing list</a> discussions about it).</p>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
<p>Currently libvirt supports 2 kind of virtualization, and its
|
||||||
|
internal structure is based on a driver model which simplifies adding new
|
||||||
|
engines:</p>
|
||||||
|
|
||||||
|
<ul><li><a href="#Xen">Xen hypervisor</a></li>
|
||||||
|
<li><a href="#QEmu">QEmu and KVM based virtualization</a></li>
|
||||||
|
<li><a href="#drivers">the driver architecture</a></li>
|
||||||
|
</ul><h3><a name="Xen" id="Xen">Libvirt Xen support</a></h3>
|
||||||
|
|
||||||
|
<p>When running in a Xen environment, programs using libvirt have to execute
|
||||||
|
in "Domain 0", which is the primary Linux OS loaded on the machine. That OS
|
||||||
|
kernel provides most if not all of the actual drivers used by the set of
|
||||||
|
domains. It also runs the Xen Store, a database of informations shared by the
|
||||||
|
hypervisor, the kernels, the drivers and the xen daemon. Xend. The xen daemon
|
||||||
|
supervise the control and execution of the sets of domains. The hypervisor,
|
||||||
|
drivers, kernels and daemons communicate though a shared system bus
|
||||||
|
implemented in the hypervisor. The figure below tries to provide a view of
|
||||||
|
this environment:</p>
|
||||||
|
<img src="architecture.gif" alt="The Xen architecture" /><p>The library can be initialized in 2 ways depending on the level of
|
||||||
|
priviledge of the embedding program. If it runs with root access,
|
||||||
|
virConnectOpen() can be used, it will use three different ways to connect to
|
||||||
|
the Xen infrastructure:</p>
|
||||||
|
<ul><li>a connection to the Xen Daemon though an HTTP RPC layer</li>
|
||||||
|
<li>a read/write connection to the Xen Store</li>
|
||||||
|
<li>use Xen Hypervisor calls</li>
|
||||||
|
<li>when used as non-root libvirt connect to a proxy daemon running
|
||||||
|
as root and providing read-only support</li>
|
||||||
|
</ul><p>The library will usually interact with the Xen daemon for any operation
|
||||||
|
changing the state of the system, but for performance and accuracy reasons
|
||||||
|
may talk directly to the hypervisor when gathering state informations at
|
||||||
|
least when possible (i.e. when the running program using libvirt has root
|
||||||
|
priviledge access).</p>
|
||||||
|
|
||||||
|
<p>If it runs without root access virConnectOpenReadOnly() should be used to
|
||||||
|
connect to initialize the library. It will then fork a libvirt_proxy
|
||||||
|
program running as root and providing read_only access to the API, this is
|
||||||
|
then only useful for reporting and monitoring.</p>
|
||||||
|
|
||||||
|
<h3><a name="QEmu" id="QEmu">Libvirt QEmu and KVM support</a></h3>
|
||||||
|
|
||||||
|
<p>The model for QEmu and KVM is completely similar, basically KVM is based
|
||||||
|
on QEmu for the process controlling a new domain, only small details differs
|
||||||
|
between the two. In both case the libvirt API is provided by a controlling
|
||||||
|
process forked by libvirt in the background and which launch and control the
|
||||||
|
QEmu or KVM process. That program called libvirt_qemud talks though a specific
|
||||||
|
protocol to the library, and connects to the console of the QEmu process in
|
||||||
|
order to control and report on its status. Libvirt tries to expose all the
|
||||||
|
emulations models of QEmu, the selection is done when creating the new
|
||||||
|
domain, by specifying the architecture and machine type targetted.</p>
|
||||||
|
|
||||||
|
<p>The code controlling the QEmu process is available in the
|
||||||
|
<code>qemud/</code> directory.</p>
|
||||||
|
|
||||||
|
<h3><a name="drivers" id="drivers">the driver based architecture</a></h3>
|
||||||
|
|
||||||
|
<p>As the previous section explains, libvirt can communicate using different
|
||||||
|
channels with the current hypervisor, and should also be able to use
|
||||||
|
different kind of hypervisor. To simplify the internal design, code, ease
|
||||||
|
maintainance and simplify the support of other virtualization engine the
|
||||||
|
internals have been structured as one core component, the libvirt.c module
|
||||||
|
acting as a front-end for the library API and a set of hypvisor drivers
|
||||||
|
defining a common set of routines. That way the Xen Daemon accces, the Xen
|
||||||
|
Store one, the Hypervisor hypercall are all isolated in separate C modules
|
||||||
|
implementing at least a subset of the common operations defined by the
|
||||||
|
drivers present in driver.h:</p>
|
||||||
|
<ul><li>xend_internal: implements the driver functions though the Xen
|
||||||
|
Daemon</li>
|
||||||
|
<li>xs_internal: implements the subset of the driver availble though the
|
||||||
|
Xen Store</li>
|
||||||
|
<li>xen_internal: provide the implementation of the functions possible via
|
||||||
|
direct hypervisor access</li>
|
||||||
|
<li>proxy_internal: provide read-only Xen access via a proxy, the proxy code
|
||||||
|
is in the <code>proxy/</code>directory.</li>
|
||||||
|
<li>xm_internal: provide support for Xen defined but not running
|
||||||
|
domains.</li>
|
||||||
|
<li>qemu_internal: implement the driver functions for QEmu and
|
||||||
|
KVM virtualization engines. It also uses a qemud/ specific daemon
|
||||||
|
which interracts with the QEmu process to implement libvirt API.</li>
|
||||||
|
<li>test: this is a test driver useful for regression tests of the
|
||||||
|
front-end part of libvirt.</li>
|
||||||
|
</ul><p>Note that a given driver may only implement a subset of those functions,
|
||||||
|
(for example saving a Xen domain state to disk and restoring it is only
|
||||||
|
possible though the Xen Daemon), in that case the driver entry points for
|
||||||
|
unsupported functions are initialized to NULL.</p>

|
the default value. The <code>id</code> attribute gives the domain id at
|
||||||
|
runtime (not however that this may change, for example if the domain is saved
|
||||||
|
to disk and restored). The domain has a few children whose order is not
|
||||||
|
significant:</p><ul><li>name: the domain name, preferably ASCII based</li>
|
||||||
|
<li>memory: the maximum memory allocated to the domain in kilobytes</li>
|
||||||
|
<li>vcpu: the number of virtual cpu configured for the domain</li>

<li>devices: a list of <code>disk</code>, <code>interface</code> and

<code>console</code> descriptions in no special order</li>
|
||||||
|
</ul><p>The format of the devices and their type may grow over time, but the
|
||||||
|
following should be sufficient for basic use:</p><p>A <code>disk</code> device indicates a block device, it can have two
|
||||||
|
values for the type attribute either 'file' or 'block' corresponding to the 2
|
||||||
|
options availble at the Xen layer. It has two mandatory children, and one
|
||||||
|
optional one in no specific order:</p><ul><li>source with a file attribute containing the path in Domain 0 to the
|
||||||
|
file or a dev attribute if using a block device, containing the device
|
||||||
|
name ('hda5' or '/dev/hda5')</li>
|
||||||
|
<li>target indicates in a dev attribute the device where it is mapped in
|

|
the guest</li>
|
||||||
|
<li>readonly an optional empty element indicating the device is
|
||||||
|
read-only</li>
|
||||||
|
</ul><p>An <code>interface</code> element describes a network device mapped on the
|
||||||
|
guest, it also has a type whose value is currently 'bridge', it also have a
|
||||||
|
number of children in no specific order:</p><ul><li>source: indicating the bridge name</li>
|

|
<li>mac: the optional mac address provided in the address attribute</li>

<li>ip: the optional IP address provided in the address attribute</li>
|

<li>script: the script used to bridge the interfcae in the Domain 0</li>
|
||||||
|
<li>target: and optional target indicating the device name.</li>
|
||||||
|
</ul><p>A <code>console</code> element describes a serial console connection to
|
||||||
|
the guest. It has no children, and a single attribute <code>tty</code> which
|
||||||
|
provides the path to the Pseudo TTY on which the guest console can be
|
||||||
|
accessed</p><p>Life cycle actions for the domain can also be expressed in the XML format,
|
||||||
|
they drive what should be happening if the domain crashes, is rebooted or is
|
||||||
|
poweroff. There is various actions possible when this happen:</p><ul><li>destroy: The domain is cleaned up (that's the default normal processing
|
||||||
|
in Xen)</li>
|
||||||
|
<li>restart: A new domain is started in place of the old one with the same
|
||||||
|
configuration parameters</li>
|
||||||
|
<li>preserve: The domain will remain in memory until it is destroyed
|
||||||
|
manually, it won't be running but allows for post-mortem debugging</li>
|
||||||
|
<li>rename-restart: a variant of the previous one but where the old domain
|
||||||
|
is renamed before being saved to allow a restart</li>
|
||||||
|
</ul><p>The following could be used for a Xen production system:</p><pre><domain>
|

<on_poweroff>destroy</on_poweroff>
|
||||||
|
<on_crash>rename-restart</on_crash>
|
||||||
|
...
|
||||||
|
</domain></pre><p>While the format may be extended in various ways as support for more
|
||||||
|
hypervisor types and features are added, it is expected that this core subset
|
||||||
|
will remain functional in spite of the evolution of the library.</p><h3 id="Fully"><a name="Fully1" id="Fully1">Fully virtualized guests</a>

for the drive is the first IDE disk device hda. The list of device names
|
||||||
|
supported is dependant on the Hypervisor, but for Xen it can be any IDE
|
||||||
|
device <code>hda</code>-<code>hdd</code>, or a floppy device
|
||||||
|
<code>fda</code>, <code>fdb</code>. The <code><disk></code> element
|
||||||
|
also supports a 'device' attribute to indicate what kinda of hardware to
|
||||||
|
emulate. The following values are supported:
|
||||||
|
<ul><li><code>floppy</code> - a floppy disk controller</li>
|
||||||
|
<li><code>disk</code> - a generic hard drive (the default it
|
||||||
|
omitted)</li>
|
||||||
|
<li><code>cdrom</code> - a CDROM device</li>
|
||||||
|
</ul>
|
||||||
|
For Xen 3.0.2 and earlier a CDROM device can only be emulated on the
|
||||||
|
<code>hdc</code> channel, while for 3.0.3 and later, it can be emulated
|
||||||
|
on any IDE channel.</li>
|
||||||
|
<li>the <code><devices></code> section also include at least one
|
||||||
|
entry for the graphic device used to render the os. Currently there is
|
||||||
|
just 2 types possible 'vnc' or 'sdl'. If the type is 'vnc', then an
|
||||||
|
additional <code>port</code> attribute will be present indicating the TCP
|
||||||
|
port on which the VNC server is accepting client connections.</li>
|
||||||
|
</ul><p>It is likely that the HVM description gets additional optional elements
|
||||||
|
and attributes as the support for fully virtualized domain expands,
|
||||||
|
especially for the variety of devices emulated and the graphic support
|
||||||
|
options offered.</p><h3><a name="KVM1" id="KVM1">KVM domain (added in 0.2.0)</a></h3><p>Support for the <a href="http://kvm.qumranet.com/">KVM virtualization</a>
|
||||||
|
is provided in recent Linux kernels (2.6.20 and onward). This requires
|
||||||
|
specific hardware with acceleration support and the availability of the
|
||||||
|
special version of the <a href="http://fabrice.bellard.free.fr/qemu/">QEmu</a> binary. Since this
|
||||||
|
relies on QEmu for the machine emulation like fully virtualized guests the
|
||||||

XML description is quite similar, here is a simple example:</p><pre><domain <span style="color: #FF0000; background-color: #FFFFFF">type='kvm'</span>>

</ul><p>except those points the options should be quite similar to Xen HVM
|
||||||
|
ones.</p><h3><a name="Net1" id="Net1">Networking options for QEmu and KVM (added in 0.2.0)</a></h3><p>The networking support in the QEmu and KVM case is more flexible, and
|
||||||
|
support a variety of options:</p><ol><li>Userspace SLIRP stack
|
||||||
|
<p>Provides a virtual LAN with NAT to the outside world. The virtual
|
||||||
|
network has DHCP & DNS services and will give the guest VM addresses
|
||||||
|
starting from <code>10.0.2.15</code>. The default router will be
|
||||||
|
<code>10.0.2.2</code> and the DNS server will be <code>10.0.2.3</code>.
|
||||||
|
This networking is the only option for unprivileged users who need their
|
||||||
|
VMs to have outgoing access. Example configs are:</p>
|
||||||
|
<pre><interface type='user'/></pre>
|
||||||
|
<pre>
|
||||||
|
<interface type='user'>
|
||||||
|
<mac address="11:22:33:44:55:66:/>
|
||||||
|
</interface>
|
||||||
|
</pre>
|
||||||
|
</li>
|
||||||
|
<li>Virtual network
|
||||||
|
<p>Provides a virtual network using a bridge device in the host.
|
||||||
|
Depending on the virtual network configuration, the network may be
|
||||||
|
totally isolated,NAT'ing to aan explicit network device, or NAT'ing to
|
||||||
|
the default route. DHCP and DNS are provided on the virtual network in
|
||||||
|
all cases and the IP range can be determined by examining the virtual
|
||||||
|
network config with '<code>virsh net-dumpxml <network
|
||||||
|
name></code>'. There is one virtual network called'default' setup out
|
||||||
|
of the box which does NAT'ing to the default route and has an IP range of
|
||||||
|
<code>192.168.22.0/255.255.255.0</code>. Each guest will have an
|
||||||
|
associated tun device created with a name of vnetN, which can also be
|
||||||
|
overriden with the <target> element. Example configs are:</p>
|
||||||
|
<pre><interface type='network'>
|
||||||
|
<source network='default'/>
|
||||||
|
</interface>
|
||||||
|
|
||||||
|
<interface type='network'>
|
||||||
|
<source network='default'/>
|
||||||
|
<target dev='vnet7'/>
|
||||||
|
<mac address="11:22:33:44:55:66:/>
|
||||||
|
</interface>
|
||||||
|
</pre>
|
||||||
|
</li>
|
||||||
|
<li>Bridge to to LAN
|
||||||
|
<p>Provides a bridge from the VM directly onto the LAN. This assumes
|
||||||
|
there is a bridge device on the host which has one or more of the hosts
|
||||||
|
physical NICs enslaved. The guest VM will have an associated tun device
|
||||||
|
created with a name of vnetN, which can also be overriden with the
|
||||||
|
<target> element. The tun device will be enslaved to the bridge.
|
||||||
|
The IP range / network configuration is whatever is used on the LAN. This
|
||||||
|
provides the guest VM full incoming & outgoing net access just like a
|
||||||
|
physical machine. Examples include:</p>
|
||||||
|

</li>
|
||||||
|
<li>Generic connection to LAN
|
||||||
|
<p>Provides a means for the administrator to execute an arbitrary script
|
||||||
|
to connect the guest's network to the LAN. The guest will have a tun
|
||||||
|
device created with a name of vnetN, which can also be overriden with the
|
||||||
|
<target> element. After creating the tun device a shell script will
|
||||||
|
be run which is expected to do whatever host network integration is
|
||||||
|
required. By default this script is called /etc/qemu-ifup but can be
|
||||||
|
overriden.</p>

||||||

|
</interface></pre>
|
||||||
|
</li>
|
||||||
|
<li>Multicast tunnel
|
||||||
|
<p>A multicast group is setup to represent a virtual network. Any VMs
|
||||||
|
whose network devices are in the same multicast group can talk to each
|
||||||
|
other even across hosts. This mode is also available to unprivileged
|
||||||
|
users. There is no default DNS or DHCP support and no outgoing network
|
||||||
|
access. To provide outgoing network access, one of the VMs should have a
|
||||||
|
2nd NIC which is connected to one of the first 4 network types and do the
|
||||||
|
appropriate routing. The multicast protocol is compatible with that used
|
||||||
|
by user mode linux guests too. The source address used must be from the
|
||||||
|
multicast address block.</p>
|
||||||
|
<pre><interface type='mcast'>
|
||||||
|
<source address='230.0.0.1' port='5558'/>
|
||||||
|
</interface></pre>
|
||||||
|
</li>
|
||||||
|
<li>TCP tunnel
|
||||||
|
<p>A TCP client/server architecture provides a virtual network. One VM
|
||||||
|
provides the server end of the netowrk, all other VMS are configured as
|
||||||
|
clients. All network traffic is routed between the VMs via the server.
|
||||||
|
This mode is also available to unprivileged users. There is no default
|
||||||
|
DNS or DHCP support and no outgoing network access. To provide outgoing
|
||||||
|
network access, one of the VMs should have a 2nd NIC which is connected
|
||||||
|
to one of the first 4 network types and do the appropriate routing.</p>
|
||||||
|
<p>Example server config:</p>
|
||||||
|
<pre><interface type='server'>
|
||||||
|
<source address='192.168.0.1' port='5558'/>
|
||||||
|
</interface></pre>
|
||||||
|
<p>Example client config:</p>
|
||||||
|
<pre><interface type='client'>
|
||||||
|
<source address='192.168.0.1' port='5558'/>
|
||||||
|
</interface></pre>
|
||||||
|
</li>
|
||||||
|
</ol><p>To be noted, options 2, 3, 4 are also supported by Xen VMs, so it is
|
||||||
|
possible to use these configs to have networking with both Xen &
|
||||||
|
QEMU/KVMs connected to each other.</p><h3>Q<a name="QEmu1" id="QEmu1">Emu domain (added in 0.2.0)</a></h3><p>Libvirt support for KVM and QEmu is the same code base with only minor
