Method getVirtualization not present about larinfo

[pschilly]

Has this been solved?

I got the same issue.. is it related to virtualization support of the device??
because I use Windows 10 and AMD chipset where chipset supports it but ACER bios have not given an update regarding it...

[Snehal-Gajjar]

i had added this code in vendor\linfo\linfo\src\Linfo\OS\Windows.php

public function getVirtualization(){

    // Time?
    if (!empty($this->settings['timer'])) {
        $t = new Timer('Determining virtualization type');
    }

    // OpenVZ host?
    if (is_file('/proc/vz/version')) {
        return array('type' => 'host', 'method' => 'OpenVZ');
    }

    // OpenVZ guest?
    elseif (is_file('/proc/vz/veinfo')) {
        return array('type' => 'guest', 'method' => 'OpenVZ');
    }

    // Veertu guest?
    if (Common::getContents('/sys/devices/virtual/dmi/id/bios_vendor') == 'Veertu') {
        return array('type' => 'guest', 'method' => 'Veertu');
    }

// LXC guest?
    if (strpos(Common::getContents('/proc/mounts'), 'lxcfs /proc/') !== false) {
        return array('type' => 'guest', 'method' => 'LXC');
    }

    // Docker guest?
    if (is_file('/.dockerenv') || is_file('/.dockerinit') || strpos(Common::getContents('/proc/1/cgroup'), 'docker') !== false) {
        return array('type' => 'guest', 'method' => 'Docker');
    }

    // Try getting kernel modules
    $modules = [];
     if (preg_match_all('/^(\S+)/m', Common::getContents('/proc/modules', ''), $matches, PREG_SET_ORDER)) {
         foreach ($matches as $match) {
             $modules[] = $match[1];
         }
     }

    // Sometimes /proc/modules is missing what is in this dir on VMs
    foreach (@glob('/sys/bus/pci/drivers/*') as $name) {
            $modules[] = basename($name);
    }

    // VMware guest. Tested on debian under vmware fusion for mac...
    if (Common::anyInArray(array('vmw_balloon', 'vmwgfx', 'vmw_vmci'), $modules)) {
        return array('type' => 'guest', 'method' => 'VMWare');
    }

    // VMware Host! tested on rhel6 running vmware..workstation?
    if (Common::anyInArray(array('vmnet', 'vmci', 'vmmon'), $modules)) {
        return array('type' => 'host', 'method' => 'VMWare');
    }

    // Looks like it might be xen...
    if (Common::anyInArray(array('xenfs', 'xen_gntdev', 'xen_evtchn', 'xen_blkfront', 'xen_netfront'), $modules) || is_dir('/proc/xen')) {

        // Guest or host?
        if (Common::anyInArray(array('xen-netback', 'xen_blkback'), $modules) || strpos(Common::getContents('/proc/xen/capabilities', ''), 'control_d') !== false) {
            return array('type' => 'host', 'method' => 'Xen');
        } else {
            return array('type' => 'guest', 'method' => 'Xen');
        }
    }

    // VirtualBox Host! Tested on lucid running vbox..
    if (in_array('vboxdrv', $modules)) {
        return array('type' => 'host', 'method' => 'VirtualBox');
    }

    // VirtualBox Guest! Tested on wheezy under mac vbox
    if (in_array('vboxguest', $modules)) {
        return array('type' => 'guest', 'method' => 'VirtualBox');
    }

    // Hyper-V guest. Tested with Trusty under Client Hyper-V in Windows 10 Pro. Needs to be checked before KVM/QEMU!
    if (Common::anyInArray(array('hid_hyperv', 'hv_vmbus', 'hv_utils'), $modules)) {
        return array('type' => 'guest', 'method' => 'Hyper-V');
    }

    // Looks like it might be KVM HOST!
    if (Common::anyInArray(array('kvm_intel', 'kvm_amd'), $modules)) {
        return array('type' => 'host', 'method' => 'KVM');
    }

    // Looks like it might be a KVM or QEMU guest! This is a bit lame since Xen can also use virtio but its less likely (?)
    if (Common::anyInArray(array('virtio', 'virtio_balloon', 'virtio_pci', 'virtio-pci', 'virtio_blk', 'virtio_net'), $modules)) {
        return array('type' => 'guest', 'method' => 'Qemu/KVM');
    }

    // idk
    return false;
 }

and I got solved virtualization error but I got swap memory error so I solved it by editing this function as ...

public function getRam()
{

    // Time?
    if (!empty($this->settings['timer'])) {
        $t = new Timer('Memory');
    }

    $total_memory = 0;
    $free_memory = 0;

    foreach ($this->wmi->ExecQuery('SELECT TotalPhysicalMemory FROM Win32_ComputerSystem') as $cs) {
        $total_memory = $cs->TotalPhysicalMemory;
        break;
    }

    foreach ($this->wmi->ExecQuery('SELECT FreePhysicalMemory FROM Win32_OperatingSystem') as $os) {
        $free_memory = $os->FreePhysicalMemory;
        break;
    }

    return array(
        'type' => 'Physical',
        'total' => $total_memory,
        'free' => $free_memory * 1024,
        'swapTotal' => 0,
        'swapFree' => 0,
    );
}

it would be great if you can create a PR for this functionality, since I don't have Windows machine.

[Snehal-Gajjar]

I need to discuss few things on this where I can contact you?

[matriphe]

we can discuss it here

[Snehal-Gajjar]

Ok, so I used your code to fix the error as a temporary patch... I don't know is it good or not but it's working.
N I think virtulization method must not to be mandatory in case of operating system varies over different platforms n devices.. n another point I got about swap memory is not exist over application level access in windows... So no use of it... It will require kernel level access.....
Another few things I want to discuss for business... If you would like to add me in LinkedIn.

[matriphe]

yes, it might need to refactor and change some methods. it’s a good idea to not make virtualization mandatory. regarding swap memory, in Windows, there’s no such that thing. you can contact me through e-mail in my Github profile.

Please check the latest release 3.0. I hope it helps. Closing it for now. If you have any issue, you can reopen this.
