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.

Dear Experts

We have to setup  an application server which is web-based (LAMP stack) for which we are planning to procure the server with 10TB disk and with vmware hypervisor , the application  server will be running on VM, it is very much important for us to setup a disaster recovery and business continuity for example if server crashes or due to physical damage at head office (primary site)  goes down then  the  server at recovery site to ensure business continuity.
 we have 2 branch offices one connected with mpls vpn to the head office where this new server going to be setup and another office is having leased line connectivity. please suggest on the following and which is the best one recommended you can add other plans please
1. while purchasing the dell server is there software  if purchased and as well procure same identical config one more server and host it in the branch office, hence 2 servers of identical configurations and the software will mirror the volume and data - if primary site goes down the recovery site comes to live for the business continuity

2. OR should we have to look for automatic vm backup with veeam and this can be configured replicate from the primary site to the recovery site

please suggest thanks in advance.

Hi ,

A new client has accidentally increased the disk space on his Parallels VM whilst it was in active in Windows. Of course its frozen and not sure what to do next. If i recall historically does it not corrupt the vm, rendering it unbootable? I dont think he took any backups so i wondered if there were any steps to recovering the virtual machine. It's running Windows 10 on a Mac book Pro.

Since upgrading to Veeam 9.5 Ive noticed I now have snapshots on two of my 4 servers which sit on the vCentre. Im down to 350gb on the main storage datastore and dont have any more space presently available. I never noticed these snapshots before on Veeam 8 but I may of not noticed but since upgrading to 9.5 a lot of space has disappeared from my datastore.

Is there a way the snapshots can be consolidated into the main vm files or do I have to provide more space?
We are setting up a small office with few ESxi hosts in the cluster. The AD domain controllers are going to be VMs.
My understanding is that the the PCs are going to sync the time with DC (PDC emulator).
Will the DCs sync the time with Esxi hosts or do we have to set the DC to sync the time with external server?
I am trying to install a custom VM into Azure using the manufacturer's instructions. I have imported the AzurePublishSettingsFile and logged onto Azure.  When I follow the next set of instructions I get errors:

I know very little about PowerShell, I only follow the directions when they are called for. I know enough to know that an object and a string are different things but I don't know how to approach fixing it. Any help would be appreciated.

We use VMware and use vSphere appliance and I was able to login into the server successfully last week.
Now if I log in, it says with a red x mark windows.
“Could not connect vSphere Client could not connect to VCT-Server
An unknown connection error occurred. ( The request failed because of a connection failure.( Unable to connect to the remote server)”

I logged into the ESX host whre the Vcenter appliance is hosted and on the server summary it says
VMware tools : Not running
IP address is .... Blank
DNS name :.. blank
State : Powered on

Any help to resolve this would be great.

Got 2 Veeam 9.5 backup jobs stopping on and Ive tried locating the VeeamAgent.exe but there are none. I followed the KB article where you stop and start services etc but this has not worked either.

Anybody come across this?

Windwos 2012, Veeam 9.5 Update 3.

I have several 2012 R2 Hyper-V servers that replicate to another server and have done this for years. One server in particular I'm having trouble.
Noticed it yesterday that the replication health was critical and started to investigate. It showed that an avhdx file was on the hosted server and the hard drive in the settings had a long name in the drive settings. Normally when you shut down the server the avhdx  will merge with its parent. This time it did not and I had  to manually merge the file, delete the VM and recreate another one and reset up the replication. Everything went fine yesterday afternoon and replication was normal. This morning I came in and again it was back in the critical state. What can I do to fix this?
After rebooting windows server 2012, it is not coming up. I only see Windows logo, no progress , nothing. I waited for 4 hours but still nothing is happening. It shows Windows logo.
This is VM machine hosted on VMWare 6.0.  I tried following
1. Rebooting in Safe mode
3. Followed some VMWare article
4. Last known good configuration

Nothing helped.
Hi there,

We have a Linux script that creates a backup .zip file nightly. Once the .zip file is created, I run another bash script to copy it to a mount directory, which is connected to an Azure VM.  That part is working just fine, but I need to only keep three days worth of backup in the Azure mount directory.  I'm running the "find" command below, but it doesn't seem to find the right files that should be deleted.  

find /data/oracle/devpdb/dpdump/ -name "oneg_*.zip" -mtime +3

It's not returning anything, but I know I have some .zip files which start with "oneg_" that are over three days old.  If I run the command below, it find the right files, but it doesn't have the check for files that are three days or older.

find /data/oracle/devpdb/dpdump/ -name "oneg_*.zip"

What am I doing wrong?

Do VMsnapshots depend on Vcenter.

I would like to know if VM Snapshoting can continue if there is no Vcenter present.

Thank you
I've tried to install WSUS on the VM server at least 7 times.   Each time it fails, stating the server needs a reboot.   As a test I installed SNMP and it installed just fine.  

Any ideas what is causing this?
Re: Imaging computers for bare metal backups.  I don't want to miss a bet regarding best practices.
So, I'm asking for comments on my beliefs and practices.
I'm trying to be as pedantic as possible in order to generate comments.  So some assertions are really, to me, DUH!  (You don't have to say "well, SURE!"     :-)
I'm currently targeting VEEAM Windows Free Agent as the tool.
There are no virtual machines.
There are no "families" of identical target hardware.

1) If it's going to be bare metal then that implies the OS drive could be empty and one has to provide a boot mechanism.

2) One has to have a boot mechanism, an image, and the image source has to be reachable by the booted recovery environment.

3) Remote access is out of the question.

4) If the computer is headless then this can complicate matters to provide HID access for the recovery environment.

5) The VEEAM backup process can keep up with changes.  So, if the objective is to back out from an OS upgrade, some selection in the recovery will be necessary.  (Assumes that using a Restore Point from within Windows isn't feasible).

6) Using VEEAM, it's necessary to have a unique boot drive.  How to avoid the uniqueness?

7) The unique boot drives have to be available or easily burned from backups.  (Which?)

8) If the unique boot drive isn't tested (including that the image file reachable) then you don't know what you have.

Some thoughts and questions:

How to manual backup for virtual machine store in the Vsphere client show in the screenshot. Do i just backup the vmdk will do?

Please note we don't have a Veeam backup and vcenter to export to OVF files and the only solution is to do a manual backup.
Cannot add host to vCenter server. My current web version is 5.5.0 Build 2175560

Basically its the same issue as this:

I realize I am running on older version of vCenter and need to update it to 3h version. The problem is I cannot download this update from MyVMware portal as when I click on download now this site says :

"You either are not entitled or do not have permissions to download this product.
Check with your My VMware Super User, Procurement Contact or Administrator.

If you recently purchased this product through VMware Store or through a third-party, try downloading later. "

And then it redirects me to 6.5 download. Since the infrasturcture I am supporting is on 5.5, I want to practise on the last version of 5.5 which is 3h.
Where can I download this newest version from ?

We use VMware and I have a Windows 2012 servers and SQL is installed on this server and strangely the server is very slow since 1 week and not responding to control panel, administrative tools, task manager and I restarted the server when I login as domain \administrator the desktop is completely black and it is not loading any desktop icons.
The vSphere client version is 5.5.0  and I also tried on the vSphere client, I right clicked the VM and open console and the screen is black here as well.

Please suggest how to resolve this and any help will be great.
I'm trying to make good use of the VEEAM free imaging tool for bare metal backups.
I can get the image files OK but have a few questions about restore operations.

Assuming that I need to apply this to a number of computers (not too large a number) and that others may have to do the restorations, I'd like to save the files on a network share rather than, say, an external USB drive that can be made "local" when the time for restoration comes.
Clearly, one is going to want to test the restoration process and I'm willing to deal with variations in computers regarding "can this one boot from a USB or DVD?".

But, in the first test using a network drive, I couldn't get the VEEAM restore system to see any network shares.
This is in a workgroup environment with a number of file shares on the network.
I've already determined that the NIC driver seems to be present and have configured its settings after / during boot to match the workgroup subnet.
But that's as far as I can get.
Also, I'm not expecting name service so use file-sharing computer IP addresses such as:

I don't want to find a solution for a one-off computer.  I want to be able to do this over a range of different computers.

Suggestions?  I'd rather not give up on a network share as the image source.  But, if that's the conventional wisdom then I guess I'll have to more seriously consider just that.
I would like to set up 2 virtual routers/appliances on a Hyper V box(MS2016).  I'm looking for a general guide or how to, if one exists.  Why? sng's, just cause, and or stretching my legs.
For this example/test

 I have already set up a test server with MS2016 configured with Hyper-V server role.  The server has 3 physical Nics.   I am using Opnsense/Pfsence as one vm, and untangle as a second vm and one Virtual switch so far.
This is kinda  what I envision

Int/Cbl Modem<----->VM1 Pub int Dhcp from Cable modem- Priv Int static<--------> VM2 Pub Int static Int static192.168.1.1 w dhcp /24

Struggling how to put it to practice in the VM environment.
Thanks in Advance
Dear Wizards, the information of host in VMware page was missing. What should I do to enable it? Many thanks

Hello, I'm learning how to use Oracle VirtualBox.  I'm trying to figure out how to share a VM accross multiple user profiles on the same machine.  I've followed the instruction from this site, -

I've done what was mentioned, rebooted now VirtualBox won't launch I keep getting the attached error.  The mentioned  Component is not listed in Component Services, am i missing something?  If i remove the settings that were mentioned on that site it'll work.

I have local disk on one of our VMware host. I'd like to either create a window share on the disk or mount this disk on a VM or create a Windows share off it. How do I go about implementing this?
Upgrading vCenter 6.0 appliance to 6.5 i encounter an error.  I am following 

I am connected to a Server 2012 vm on the network and run the upgrade. I am on the VUM server and it fails.  If i unregister VUM, will the migration continue?


I installed a new vcenter 6.5 appliance. I am unable to get to the vsphere-client web page by IP or fqdn (https://ip or fqdn/vsphere-client). I can get to the psc web page both by IP and fqdn. I set up DNS before installing the appliance. I am able to ping the fqdn and the IP. I have restarted the appliance but still get an error. I have attached a screen shot of the error.

I appreciate any help troubleshooting this.
