A few basic examples

Example #1 Libvirt Example

`<?php
$uri="qemu+tcp:///system";
$credentials=Array(VIR_CRED_AUTHNAME=>"fred",VIR_CRED_PASSPHRASE=>"fred");
echo ("Connecting to libvirt (URI:$uri)\n");
$conn=libvirt_connect($uri,false,$credentials);
if ($conn==false)
{
echo ("Libvirt last error: ".libvirt_get_last_error()."\n");
exit;
}
else
{
$hostname=libvirt_get_hostname($conn);
echo ("hostname:$hostname\n");
echo ("Domain count: Active ".libvirt_get_active_domain_count($conn).",Inactive ".libvirt_get_inactive_domain_count($conn).", Total ".libvirt_get_domain_count($conn)."\n");
$domains=libvirt_list_domains($conn);
foreach ($domains as $dom)
{
echo ("Name:\t".libvirt_domain_get_name($dom)."\n");
echo("UUID:\t".libvirt_domain_get_uuid_string($dom)."\n");
$dominfo=libvirt_domain_get_info($dom);
print_r($dominfo);
}
}
?>`

The above example will output something similar to:
