Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Hi all and happy Sysadmin Day!

I have a hyper-v 2012 R2 host. I'm backing up one of the VMs and noticed that Veeam is only backing up the C: VHD disk, it's not backing up the other VHD disk which is H:
what could I look at to determine why it's not backing up the 2nd VHD disk on this VM?

We have a production site and a DR site.

We have Veeam installed on the production site. Among others, Veeam replicates the backups and the virtual machines to the DR site.

As part of the replication jobs, I would like to know if we can replicate the Veeam backup server to the DR site and if there is any best practices that must be followed for such scenario.

In VMware, is there a way to emulate disk drives that reside in a canister that connects to the back of an ESXi Server?

We have some VMs on a 6.0 vSphere system that accesses a real canister of disk attached to an ESXi Server.  I think RDM is used. We do not have the canister and cannot obtain one or attach it to our ESXi Server

Is there a way to emulate the disk drive connection in VMware?

Possibly by using datastores, shared drives, or even a USB device (RDM) ?

thanks

Hi,

 I have a Hyper-V virtual machine "TS3" running Windows Server 2008 with 278GB space allocated, but only using 100GB of space.

So I wanted to shrink the VHDX size. When I ran "Shrink" option in Disk Mgmt.msc, I got an error "Access denied".

I tried different suggestions on Google, but to no avail. So I ran Disk2VHD in TS3 and it created 72GB VHDX file.
Then I created a new VM "TS3 - VHDX" using existing 72GB VHDX file. But when I fired up the new VM, it still shows that hard drive size is 278GB in "My Computer".

Furthermore, when I tried to shrink it using DiskMgmt.msc, I still get "Access denied"error.
I don't mind seeing 278GB in "My Computer" of the VM as long as real size of VHDX is till 72GB.

My objective is to reduce the VHDX file and free up overall hard drive space on HyperV server.
But I am curious why the VM would not display current HD size based on VHDX file size?

Trying to install Volume Activation Management Tool on a 2012 R2 Virtual server.  I installed the VAMT from the Windows 10 ADK.   This VM did not have SQL installed.  When I opened VAMT and it prompts to install Microsoft SQL server express and I chose to do that.  It installed SQL Express 2017.  When VAMT tries to connect to the VAMT database, it opens the database connection settitng dialog.  I have tried to enter the current VM name as the server and VAMT as the database name and if fails with this error:
"A network-related or instance-specific error occurred while establishing a connection to SQL Server.  The server was not found or was not accessible.  Verify that the instance name is correct and that SQL Server is configures to allow remote connections.  (Provider: Named Pipes Provider, error: 40. Could not open a connection to SQL Server).
I have no idea on what to do with SQL, I have never installed on a Virtual server so maybe that is the problem.  In the past on other servers, after choosing to install SQL, I have been able to create and connect to just by using the servername and 'VAMT' in the database connection.
If you can point me in the right direction, it would be greatly appreciated.

I am using VMPlayer 15 to run a Windows 7 guest operating system on a Windows 10 PC.  I have been having problems with the guest OS lately that I can't explain.  The guest OS runs very slowly, there have been network connection issues, there have been problems using multiple monitors and most annoyingly, the mouse seems to randomly switch back to the host.  My "gut" is telling me that the guest is to big for the host.  When I say too big, I mean that the guest is configured so that it is more powerful than the host can handle.  I am not even sure if that is possible using VMPlayer.

What is the minimum requirement for a server CPU  in terms of cores and Hertz.
I speak about a windows 2016 server which it will work only as file server without any virtualization

I think a 10 cores cpu at 2GHz it will be ok. Isn't it?
If not what are the minimum requirement?

In another case for a server with 2 VM what are the minimum requirement for the CPU?

In Vsphere 6.7 where on earth are the Advanced CPU HT Sharing:  Options!!!!  I have looked in both the HTML and Web client and cant find these options!

Here is a screenshot from Vsphere 5.0 console showing clearly where these options are located:
Edit VM
Can anyone help point me in the right direction?

I need these same options because I do not want to share any CPU with any other vm so I need to find this same option in Vsphere 6.7 and choose "None"

Thanks

This is a SuSE 11 with SP3 virtual machine. In /var/log/message, i found a line as follows,

     "2019-07-19T17:03:17.852797+08:00 zlnx01 org.a11y.atspi.Registry[24075]: XIO: fatal IO error 11 (Resource temporarily unavailable) on X server "localhost:10.0"")

What is this error about? Does this refer to the "X windows" of sshd. btw, only sshd is running (remote desktop). This error only happens once. Does this sort of soft error?

Thanks in advance.

I am trying to retrieve user input from a form in my PHP web app so that i can assign these values to variables with the $_POST[' '] command. Then, i want to make changes to a database with the values retrieved. But my problem is that the $_POST[' '] command is returning empty values for every field i put information in..
To put into context, i am using Oracle VM VirtualBox with a Linux VM, and within this i use the Eclipse Workspace to code my program. Here is the php file with the code that is not working:

<?php 
require "init.php";

if(empty($_SERVER['CONTENT_TYPE'])) {
    $SERVER['CONTENT_TYPE'] = "application/x-www-form-urlencoded";
}

if (!isset($_SESSION['NOM_UTILISATEUR'])) {
    echo "<script>alert('Vous n'êtes pas actuellement connecté ! Redirection vers la page de connexion ...');
    window.location='index.php'</script>";
    session_destroy();
}

$_POST['SELECT_ENCAN'] = "";
$_POST['DESCRIPTION'] = "";
$_POST['TITRE'] = "";
$_POST['DONATEUR_MAJ'] = "";
$_POST['VALEUR'] = "";
$_POST['PRIX_INITIAL'] = "";
$_POST['INCR_MIN'] = "";
$_POST['ACH_IMM'] = "";
$_POST['PHOTO'] = "";

$select_encan = "";
$titre = "";
$description = "";
$donateur_maj = "";
$valeur = "";
$prix_ini = "";
$incr_min = "";
$ach_imm = "";
$chemin_photo = "";

$page_ajout = $_SESSION['Ajouter'];
$page_maj = $_SESSION['MAJ'];

if ($page_ajout == true) {
    if (isset($_POST['OK_MAJ'])) {
      
        $titre = $_POST['TITRE'];
        $description = $_POST['DESCRIPTION'];
        

Open in new window

Core 2016 Hyper-V with VM DC, network adaptor showing no IP address. The hyper V management console will no longer connect from my workstation. It is the only DC in our network which is just a few computers. I can see the machine is running on the host but the IP address is showing as {}

Is there a way I can set the IP address of the adaptor on the host? All searches on Google say it should be done from the Management console.

I have a full Windows Image Backup of a server running 2008 Standard. I need to create a virtual machine (hyper-v) from this backup. I have done this before, but I can't remember what I did. I know boot up with an ISO and go into system restore, but once I get there I cannot access the USB media that contains the backup. Any suggestions!?

The server im trying to restore was a standalone server.

We want to deploy a simple VDI infrastructure based on Windows Server 2019 RDS.

We have a two node S2D cluster and we would like to know if we can use this cluster as the RDS virtualization host.

I want to setup a Hyper-V virtual server on a Server 2012 or 2016.  My understanding is that they both allow for 2 VM licenses.  Do these licenses include the server license to install on the VM.  Do you use the same product key as the server.  Having a difficult time finding the information on the Hyper-V licensing.  Seems like there are many different opinions on what is included and how it all works.
Any help would be appreciated.

This is about the new virtualization using VMware with simplivity hyperconverge. My parent company is heading toward this direction, probably with HPE hardware solution. We are looking for 6-8 hosts implementation. Where can find more and further information about the technology?

Thanks in advance.

Windows server data volume sizes - thoughts?
Hey there - we have an older windows server with about a 900GB partition for data that is about 90% full.  Actually setting up a new VM, and creating the volumes.
Anything I should take into consideration about watching the sizes of the vmdk not concerned here really about size limitations of the vmdk, but from a Windows Server data volume size perspective.  Is there a point if I were to go to 1 or 2 GB that it could take excessively long to defrag, or any concerns about integrity?  I would think not. but just wondering.

Thanks guys!

Hi

I built a new Windows 2019 VM by cloning the Server template and when I went to configure the IP address, I was not able to see the network adapter .
I went to device manager and on the Ethernet controller, it has an exclamation mark.
Please see the snapshot, do I need to install any drivers, and do I need to choose a different adapter.

Please help any tutorial will be great.

Thanks

I am moving some roles from a physical server to a virtual server and was wondering what the order of operations should be. I have a physical server that is a domain controller (no fsmo roles), network policy server and a certificate server. I will have the same roles on the virtual server. Both servers are running Windows 2016.

Hi

We use VMware Vsphere 6.0 and I have a Windows 2016 template server which is in a powered off state. At the moment I want to copy this server and build for the purpose of new role and would like to keep the master copy Windows 2016 template server.
If I copy the 2016 template server, will the copied sever have a separate MAC address?

Please post me the steps and best way to achieve this.

Thanks

Regarding VMware Advisory ID |VMSA-2019-0008
https://www.vmware.com/in/security/advisories/VMSA-2019-0008.html

Did checked the KB article -have few queries in mind to confirm with experts so that Fix can be applied if required
For Sequential and Concurrent Attack- Fix to be applied....

[1] Do We need to First Upgrade VC/VCSA  to Fixed Version -which is yet showing as Pending OR if we simply can make changes @Esxi -Advanced Setting - for Value  known as
VMkernel.Boot.hyperthreadingMitigation
?

[2] What all are precautions /prerequisites  if We need to verify for running applications /certificates/SSL in use @VM on different host under VC?

[3] There are Few Host  showing warning with
esx.problem.hyperthreading.unmitigate
-So Can We simply update the Value to fix the issue or nay more prerequisites  required ?

[4] There are Host in VCHost showing Options to enable/ disable fix where we are not able to locate the value to be updated ? while there are host where we can locate n update the value ?
Is It limited to specific version/Patch @VC /Esxi ? Host Not showing Options to enable/ disable fix
Please help if we can plan for fix if it is required  ?
