[libvirt] Problem with libvirt daemon

[Wouter - Iamotor]

Hello,

My bad, I thought it said that it was running but it that the daemon wasn't doing anything.

Because when I try to run this php script:
<?php
$uri="qemu+tcp:///system";
$credentials=Array(VIR_CRED_AUTHNAME=>"team7",VIR_CRED_PASSPHRASE=>"password");
echo ("Connecting to libvirt (URI:$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 script can also be found on this link:
http://phplibvirt.cybersales.cz/bightml.html

Then I get this error:
Connecting to libvirt (URI:qemu+tcp:///system) Libvirt last error: unable to connect to server at 'localhost:16509': Connection refused

The user team7 is added to the group libvirtd and kvm.

Which configuration is necessary so that the script could run on the server?

Thanks for your help so far.

With kind regards,
Wouter.

Err, that shows precisely the opposite of what you say. It shows that you have libvirtd running *5* times, no doubt due to you deleting the pidfiles.
