<h1>VMware ESX hypervisor driver</h1>

<p>
The libvirt VMware ESX driver can manage VMware ESX/ESXi 3.5/4.0 and
VMware GSX 2.0, also called VMware Server 2.0, and possibly later
versions.

None. Any out-of-the-box installation of ESX/GSX should work. No
preparations are required on the server side, no libvirtd must be
installed on the ESX server. The driver uses version 2.5 of the remote,

Therefore, change the prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway. Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option to false in case the MAC address doesn't fall into any predefined range. * docs/drvesx.html.in: update website accordingly * src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29 * src/esx/esx_vmx.c: fix MAC address range handling and allow arbitrary MAC addresses * tests/vmx2xml*, tests/xml2vmx*: add some basic MAC address range tests

<h2><a name="uri">Connections to the VMware ESX driver</a></h2>
<p>
Some example remote connection URIs for the driver are:
</p>
<pre>
esx://example.com (ESX over HTTPS)
gsx://example.com (GSX over HTTPS)
esx://example.com/?transport=http (ESX over HTTP)
esx://example.com/?no_verify=1 (ESX over HTTPS, but doesn't verify the server's SSL certificate)

esx: Improve documentation about remote URIs
2010-03-13 05:09:11 +08:00
<p>
<strong>Note</strong>: In contrast to other drivers, the ESX driver is
a client-side-only driver. It connects to the ESX server using HTTP(S).
Therefore, the <a href="remote.html">remote transport mechanism</a>
provided by the remote driver and libvirtd will not work, and you
cannot use URIs like <code>esx+ssh://example.com</code>.

<h3><a name="uriformat">URI Format</a></h3>
<p>
URIs have this general form ('[...]' marks an optional part).
</p>
<pre>
type://[username@]hostname[:port]/[?extraparameters]
</pre>
<p>
The <code>type://</code> is either <code>esx://</code> or
<code>gsx://</code> and the driver selects the default port depending
on it. For ESX the default HTTPS port is 443, for GSX it is 8333. If
the port parameter is given, it overrides the default port.
</p>
<h4>Extra parameters</h4>
<p>
Extra parameters can be added to a URI as part of the query string
(the part following '?'). The driver understands the extra parameters
shown below.

<h3><a name="auth">Authentication</a></h3>
<p>
In order to perform any useful operation the driver needs to log into
the ESX server. Therefore, only <code>virConnectOpenAuth</code> can be
used to connect to an ESX server, <code>virConnectOpen</code> and
<code>virConnectOpenReadOnly</code> don't work.
To log into an ESX server or vCenter the driver will request
credentials using the callback passed to the
<code>virConnectOpenAuth</code> function. The driver passes the
hostname as challenge parameter to the callback. This enables the
callback to distinguish between requests for ESX server and vCenter.
</p>
<p>
<strong>Note</strong>: During the ongoing driver development, testing
is done using an unrestricted <code>root</code> account. Problems may
occur if you use a restricted account. Detailed testing with restricted
accounts has not been done yet.

<h2><a name="questions">Questions blocking tasks</a></h2>
<p>
Some methods of the VI API start tasks, for example
<code>PowerOnVM_Task()</code>. Such tasks may be blocked by questions
if the ESX server detects an issue with the domain that requires user
interaction. The ESX driver cannot prompt the user to answer a
question, libvirt doesn't have an API for something like this.
</p>
<p>
The VI API provides the <code>AnswerVM()</code> method to
programmatically answer a questions. So the driver has two options
how to handle such a situation: either answer the questions with the
default answer or report the question as an error and cancel the
blocked task if possible. The
<a href="#uriformat"><code>auto_answer</code></a> query parameter
controls the answering behavior.

<p>
Storage is managed in datastores. VMware uses a special path format to
reference files in a datastore. Basically, the datastore name is put
into squared braces in front of the path.
</p>
<pre>
[datastore] directory/filename
</pre>
<p>
To define a new domain the driver converts the domain XML into a
VMware VMX file and uploads it to a datastore known to the ESX server.
Because multiple datastores may be known to an ESX server the driver
needs to decide to which datastores the VMX file should be uploaded.
The driver deduces this information from the path of the source of the
first file-based harddisk listed in the domain XML.

<h3><a name="macaddresses">MAC addresses</h3>

VMware has registered two MAC address prefixes for domains:

<p>
The VMX files generated by the ESX driver always contain a MAC address,
because libvirt generates a random one if an interface element in the
domain XML file lacks a MAC address.
<span class="since">Since 0.7.6</span> the ESX driver sets the prefix
for generated MAC addresses to <code>00:0c:29</code>. Before 0.7.6
the <code>00:50:56</code> prefix was used. Sometimes this resulted in
the generation of out-of-range MAC address that were rejected by the
ESX server.
</p>
<p>
Also <span class="since">since 0.7.6</span> every MAC address outside
this ranges can be used. For such MAC addresses the ESX server-side
check is disabled in the VMX file to stop the ESX server from rejecting
out-of-predefined-range MAC addresses.

The ESX driver currently supports a native config format known as
<code>vmware-vmx</code> to handle VMware VMX configs.

<h3><a name="xmlimport">Converting from VMware VMX config to domain XML config</a></h3>

The <code>virsh domxml-from-native</code> provides a way to convert an

<h2><a name="scheduler">Scheduler configuration</a></h2>
<p>
The driver exposes the ESX CPU scheduler. The parameters listed below
are available to control the scheduler.
</p>
<dl>
<dt><code>reservation</code></dt>
<dd>
The amount of CPU resource in MHz that is guaranteed to be
available to the domain. Valid values are 0 and greater.
</dd>
<dt><code>limit</code></dt>
<dd>
The CPU utilization of the domain will be
limited to this value in MHz, even if more CPU resources are
available. If the limit is set to -1, the CPU utilization of the
domain is unlimited. If the limit is not set to -1, it must be
greater than or equal to the reservation.
</dd>
<dt><code>shares</code></dt>
<dd>
Shares are used to determine relative CPU
allocation between domains. In general, a domain with more shares
gets proportionally more of the CPU resource. Valid values are 0
and greater. The special values -1, -2 and -3 represent the
predefined shares level <code>low</code>, <code>normal</code> and
<code>high</code>.
</dd>
</dl>
<h2><a name="tools">VMware tools</a></h2>
<p>
Some actions require installed VMware tools. If the VMware tools are
not installed in the guest and one of the actions below is to be
performed the ESX server raises an error and the driver reports it.
