<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
privilege 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>

<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 information at
program running as root and providing read_only access to the API, this is
then only useful for reporting and monitoring.</p>

<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

<h2>Hourly development snapshots</h2>
<p>
Once an hour, an automated snapshot is made from the latest CVS server
source tree. These snapshots should be usable, but we make no guarantees
about their stability:

<h1>Handling of errors</h1>
<p>The main goals of libvirt when it comes to error handling are:</p>
- <ul>
- <li>provide as much detail as possible</li>
- <li>provide the information as soon as possible</li>
- <li>dont force the library user into one style of error handling</li>
- </ul>
+ <ul><li>provide as much detail as possible</li><li>provide the information as soon as possible</li><li>dont force the library user into one style of error handling</li></ul>
<p>As result the library provide both synchronous, callback based and
asynchronous error reporting. When an error happens in the library code the
error is logged, allowing to retrieve it later and if the user registered an
dynamic structure which can be made thread specific. Error callback can be
set specifically to a connection with</p>
<p>So error handling in the code is the following:</p>
- <ol>
- <li>if the error can be associated to a connection for example when failing
+ <ol><li>if the error can be associated to a connection for example when failing
to look up a domain
<ol><li>if there is a callback associated to the connection set with <a href="html/libvirt-virterror.html#virConnSetErrorFunc">virConnSetErrorFunc</a>,
call it with the error information</li><li>otherwise if there is a global callback set with <a href="html/libvirt-virterror.html#virSetErrorFunc">virSetErrorFunc</a>,
call it with the error information</li><li>otherwise call <a href="html/libvirt-virterror.html#virDefaultErrorFunc">virDefaultErrorFunc</a>
which is the default error function of the library issuing the error
- on stderr</li><li>save the error in the connection for later retrieval with <a href="html/libvirt-virterror.html#virConnGetLastError">virConnGetLastError</a></li></ol></li>
- <li>otherwise like when failing to create an hypervisor connection:
+ on stderr</li><li>save the error in the connection for later retrieval with <a href="html/libvirt-virterror.html#virConnGetLastError">virConnGetLastError</a></li></ol></li><li>otherwise like when failing to create an hypervisor connection:
<ol><li>if there is a global callback set with <a href="html/libvirt-virterror.html#virSetErrorFunc">virSetErrorFunc</a>,

+ on stderr</li><li>save the error in the connection for later retrieval with <a href="html/libvirt-virterror.html#virGetLastError">virGetLastError</a></li></ol></li></ol>
<p>In all cases the error information is provided as a <a href="html/libvirt-virterror.html#virErrorPtr">virErrorPtr</a> pointer to
read-only structure <a href="html/libvirt-virterror.html#virError">virError</a> containing the
following fields:</p>
- <ul>
- <li>code: an error number from the <a href="html/libvirt-virterror.html#virErrorNumber">virErrorNumber</a>
- enum</li>
- <li>domain: an enum indicating which part of libvirt raised the error see
- <a href="html/libvirt-virterror.html#virErrorDomain">virErrorDomain</a></li>
- <li>level: the error level, usually VIR_ERR_ERROR, though there is room for
- warnings like VIR_ERR_WARNING</li>
- <li>message: the full human-readable formatted string of the error</li>
- <li>conn: if available a pointer to the <a href="html/libvirt-libvirt.html#virConnectPtr">virConnectPtr</a>
- connection to the hypervisor where this happened</li>
- <li>dom: if available a pointer to the <a href="html/libvirt-libvirt.html#virDomainPtr">virDomainPtr</a> domain
- targeted in the operation</li>
- </ul>
+ <ul><li>code: an error number from the <a href="html/libvirt-virterror.html#virErrorNumber">virErrorNumber</a>
+ enum</li><li>domain: an enum indicating which part of libvirt raised the error see
+ <a href="html/libvirt-virterror.html#virErrorDomain">virErrorDomain</a></li><li>level: the error level, usually VIR_ERR_ERROR, though there is room for

+ targeted in the operation</li></ul>
<p>and then extra raw information about the error which may be initialized
to 0 or NULL if unused</p>
- <ul>
- <li>str1, str2, str3: string information, usually str1 is the error
- message format</li>
- <li>int1, int2: integer information</li>
- </ul>
+ <ul><li>str1, str2, str3: string information, usually str1 is the error
+ message format</li><li>int1, int2: integer information</li></ul>
<p>So usually, setting up specific error handling with libvirt consist of
registering an handler with with <a href="html/libvirt-virterror.html#virSetErrorFunc">virSetErrorFunc</a> or
with <a href="html/libvirt-virterror.html#virConnSetErrorFunc">virConnSetErrorFunc</a>,

<h1>Python API bindings</h1>
virConnect or virDomain(Get) prefix and the first letter gets converted to
lower case, for example the C functions:</p>
<p>
-
<code>int <a href="html/libvirt-libvirt.html#virConnectNumOfDomains">virConnectNumOfDomains</a>
+ <code>int <a href="html/libvirt-libvirt.html#virConnectNumOfDomains">virConnectNumOfDomains</a>
(virConnectPtr conn);</code>
- </p>
+ </p>
<p>
-
<code>int <a href="html/libvirt-libvirt.html#virDomainSetMaxMemory">virDomainSetMaxMemory</a>
+ <code>int <a href="html/libvirt-libvirt.html#virDomainSetMaxMemory">virDomainSetMaxMemory</a>
(virDomainPtr domain, unsigned long memory);</code>
- </p>
+ </p>
<p>become</p>
<p>
- <code>virConn::numOfDomains(self)</code>
- </p>
+ <code>virConn::numOfDomains(self)</code>
+ </p>
<p>
- <code>virDomain::setMaxMemory(self, memory)</code>
- </p>
+ <code>virDomain::setMaxMemory(self, memory)</code>
+ </p>
<p>This process is fully automated, you can get a summary of the conversion
in the file libvirtclass.txt present in the python dir or in the docs.There
is a couple of function who don't map directly to their C counterparts due to
specificities in their argument conversions:</p>

is replaced by <code>virDomain::listDomainsID(self)</code> which returns

is replaced by <code>virDomain::info()</code> which returns a list of
- <ol><li>state: one of the state values (virDomainState)</li><li>maxMemory: the maximum memory used by the domain</li><li>memory: the current amount of memory used by the domain</li><li>nbVirtCPU: the number of virtual CPU</li><li>cpuTime: the time used by the domain in nanoseconds</li></ol></li>

<p>So let's look at a simple example inspired from the <code>basic.py</code>
test found in <code>python/tests/</code> in the source tree:</p>
<pre>import <span style="color: #0071FF; background-color: #FFFFFF">libvirt</span>
print dom0.<span style="color: #FF0080; background-color: #FFFFFF">info</span>()</pre>
<p>There is not much to comment about it, it really is a straight mapping
from the C API, the only points to notice are:</p>
- <ul>
- <li>the import of the module called <code><span style="color: #0071FF; background-color: #FFFFFF">libvirt</span></code></li>
- <li>getting a connection to the hypervisor, in that case using the
- openReadOnly function allows the code to execute as a normal user.</li>
- <li>getting an object representing the Domain 0 using <span style="color: #007F00; background-color: #FFFFFF">lookupByName</span></li>
- <li>if the domain is not found a libvirtError exception will be raised</li>
- <li>extracting and printing some information about the domain using

<h1>Connection URIs</h1>
To this end, libvirt uses URIs as used on the Web and as defined in <a href="http://www.ietf.org/rfc/rfc2396.txt">RFC 2396</a>. This page
documents libvirt URIs.

<p>
The URI is passed as the <code>name</code> parameter to <a href="html/libvirt-libvirt.html#virConnectOpen"><code>virConnectOpen</code></a> or <a href="html/libvirt-libvirt.html#virConnectOpenReadOnly"><code>virConnectOpenReadOnly</code></a>. For example:
</p>
virConnectPtr conn = virConnectOpenReadOnly (<b>"test:///default"</b>);

<p>
In virsh use the <code>-c</code> or <code>--connect</code> option:
</p>
virt-install <b>--connect=test:///default</b> <i>[other options]</i>

0.2.3. For libvirt ≤ 0.2.3 use <a href="#URI_legacy_xen"><code>"xen"</code></a>.</i>
- </p>

<p>
To access a Xen hypervisor running on the local machine
use the URI <code>xen:///</code>.

- </h3>
+ <a name="URI_qemu" id="URI_qemu">qemu:///... QEMU and KVM URIs</a>
+ </h3>
<p>
To use QEMU support in libvirt you must be running the
<code>libvirtd</code> daemon (named <code>libvirt_qemud</code>
<p>
So to connect to the daemon, one of two different URIs is used:
</p>
- <ul>
- <li><code>qemu:///system</code> connects to a system mode daemon. </li>
- <li><code>qemu:///session</code> connects to a session mode daemon. </li>
- </ul>
+ <ul><li><code>qemu:///system</code> connects to a system mode daemon. </li><li><code>qemu:///session</code> connects to a session mode daemon. </li></ul>
<p>
(If you do <code>libvirtd --help</code>, the daemon will print
out the paths of the Unix domain socket(s) that it listens on in
here</a>.

<a name="URI_remote" id="URI_remote">Remote URIs</a>
- </h3>
+ <a name="URI_remote" id="URI_remote">Remote URIs</a>

<p>
Remote URIs are formed by taking ordinary local URIs and adding a
hostname and/or transport name. For example:
</p>
- <table class="top_table">
- <tr>
- <th> Local URI </th>
- <th> Remote URI </th>

Remote URIs in libvirt offer a rich syntax and many features.
We refer you to <a href="remote.html#Remote_URI_reference">the libvirt

The test driver is a dummy hypervisor for test purposes.
The URIs supported are:
</p>
- <ul>
- <li><code>test:///default</code> connects to a default set of
-host definitions built into the driver. </li>

The above steps should also build and install Python modules.
However for reasons which I don't fully understand, Python won't
look in the
directory by default so you may need to set the environment
variable PYTHONPATH:
</p>
+ <pre>
export PYTHONPATH=/usr/local/lib/python2.5/site-packages
</pre>
+ <p>
(Change the version number to your version of Python). You
can test Python support from the command line:
</p>
+ <pre>
python
>>> import libvirt
>>> conn = libvirt.open ("test:///default")
>>> dom.XMLDesc (0)
"<domain type='test' id='1'> ..."
</pre>
+ <p>
The most common failure will be with <code>import libvirt</code>
which usually indicates that either <code>PYTHONPATH</code> is
wrong or a DLL cannot be loaded.
