<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>.

The <code>type://</code> is either <code>esx://</code> or

2010-07-18 15:27:05 +00:00
|
|
|
<code>gsx://</code> or <code>vpx://</code> <span class="since">since 0.8.3</span>.
|
|
|
|
|
The driver selects the default port depending on the <code>type://</code>.
|
|
|
|
|
For <code>esx://</code> and <code>vpx://</code> the default HTTPS port
|
|
|
|
|
is 443, for <code>gsx://</code> it is 8333.
|
|
|
|
|
If the port parameter is given, it overrides the default port.

|
A <code>vpx://</code> connection is currently restricted to a single
|
|
|
|
|
ESX server. This might be relaxed in the future. The path part of the
|
|
|
|
|
URI is used to specify the datacenter and the ESX server in it. If the
|
|
|
|
|
ESX server is part of a cluster then the cluster has to be specified too.

|
|
|
|
</p>

|
|

An example: ESX server <code>example-esx.com</code> is managed by
|
|

|
|
vCenter <code>example-vcenter.com</code> and part of cluster
|

|

Datacenters and clusters can be organized in folders, those have to be

<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.

<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.

<p>

By default the ESX driver uses HTTPS to communicate with an ESX server.
|
|
|
|
|
Proper HTTPS communication requires correctly configured SSL
|
|
|
|
|
certificates. This certificates are different from the ones libvirt
|
|
|
|
|
uses for <a href="remote.html">secure communication over TLS</a> to a
|
|
|
|
|
libvirtd one a remote server.
|
|
|
|
|
</p>
|
|
|
|
|
<p>
|
|
|
|
|
By default the driver tries to verify the server's SSL certificate
|
|
|
|
|
using the CA certificate pool installed on your client computer. With
|
|
|
|
|
an out-of-the-box installed ESX server this won't work, because a newly
|
|
|
|
|
installed ESX server uses auto-generated self-signed certificates.
|
2020-10-02 14:07:27 +00:00
|
|
|
Those are signed by a CA certificate that is typically not known to your
|
2010-10-22 13:01:21 +00:00
|
|
|
client computer and libvirt will report an error like this one:
|
|
|
|
|
</p>
|
|
|
|
|
<pre>
|
|
|
|
|
error: internal error curl_easy_perform() returned an error: Peer certificate cannot be authenticated with known CA certificates (60)

|
</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
Use the <code>no_verify=1</code> <a href="#extraparams">extra parameter</a>
|
|
|

to disable server certificate verification.
|
|
|
|
|
</li>
|
|
|
|
|
<li>
|
|
|
|
|
Generate new SSL certificates signed by a CA known to your client

|
computer and replace the original ones on your ESX server. See the

|

<h2><a id="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.

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>

</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
|
2010-07-18 15:27:05 +00:00
|
|
|
needs to decide to which datastore the VMX file should be uploaded.
|
2009-11-13 21:43:10 +00:00
|
|
|
The driver deduces this information from the path of the source of the
|
|
|
|
|
first file-based harddisk listed in the domain XML.

VMware has registered two MAC address prefixes for domains:

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>

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.

<span class="since">Since 6.6.0</span>, one can force libvirt to keep the

<code>type="static"</code> attribute to the <code><mac/></code> element.

Note that this attribute is useless if the provided MAC address is outside of

The ESX driver currently supports a native config format known as

<code>vmware-vmx</code> to handle VMware VMX configs.

A migration cannot be initiated on an ESX server directly, a VMware
|
2009-11-22 20:00:15 +00:00
|
|
|
vCenter is necessary for this. The <code>vcenter</code> query
|
|
|
|
|
parameter must be set either to the hostname or IP address of the
|
|
|
|
|
vCenter managing the ESX server or to <code>*</code>. Setting it
|
|
|
|
|
to <code>*</code> causes the driver to connect to the vCenter known to
|
|
|
|
|
the ESX server. If the ESX server is not managed by a vCenter an error
|
|
|
|
|
is reported.

ESX server <code>example-src.com</code> to ESX server

<span class="since">Since 0.8.3</span> you can directly connect to a vCenter.

using <code>vpx://</code> connections and assuming both ESX server are in

The driver exposes the ESX CPU scheduler. The parameters listed below
|
|
|
|
|
are available to control the scheduler.
|

|
|
|
|
|
<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>.
