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.

One of my customer tried to do some maintenance. He checked in his datastore there were only 2 datastores except local datastore.
He just added a new LUN and deleted the newly added LUN and now there was a VM with OS installed now that VM is not booting.
I checked the VM in another VM and found zero data in it.
SAN is Huawei Oceanstore 2200

How to recover this data for him?
Now the company is stopped work due to this VM stopped.
It will be a great help if anyone can help/guide

Hi all,

We've got 2 VM's on 2 Physical Hyper V servers running RDS and so have a collection (let's say RDSCollection) that the users use and are redirected via a broker on one of them and we need to add a VDI environment running some Windows 10 VM's but i've not done VDI before and having a quick look at the guides they do mention about it being installed on the physical server and not on the VM so can anyone clarify what i roles/services i need to install on the physical and what i need on the VM's ?
Also i was planning at the end of this to be able to put 2 icons on the end users thin clients (one for RDS and one for VDI) but is this possible ?
if you replicate data between your primary SAN to a DR SAN, what assurances and checks need to be performed to verify the health/reliability of the link between the sites and the replication process? What risks are there with such a setup, and what best practices/monitoring need to be in place to minimise those risks? what evidence could be requested to verify these risks are well managed with best practices?
Backup was running fine for a couple of months until recently. Error: VSSControl: Failed to freeze quest over network, wait timeout.

Restarted server, repaired SQLVSS Writer, increased timeout as recommended by Veeam, changed service to domain administrator, VsPhere able to take snap and another backup software able to do application aware backup.

I want to make an appointment:

I have a virtual machine with two virtual disks in my production environment. Reviewing the datastore, I noticed that one of the disks is stored in a different folder, however the VM works without errors.

I want to move the virtual disk to its corresponding folder. My question is the following, to move the virtual disk to its respective folder,

Should the VM be turned off?
Or can I move the disk to its corresponding folder with the VM on?

When moving the virtual disk should do it directly from the ESXi?

Or from the Vcenter?

Would it have any affect on my VM to move the virtual disk, with the server on?

Stay tuned to your comments.

I have had a number of VM's replicated from one Server 2012 R2 Hyper-v host to another. At some point more than half went critical and I was not able to place them back into 'normal' status. I removed the replication and tried to enable the replication and when I do I get the following error message: Hyper-v is not in a state to accept replication on the replica server for virtual machine 'server name'. Following many of the support posts, I tried to remove the replicated servers from the replication server but I am not able to because it says that the server is in use. Not really sure where from or how to remove the replicated server so that we can re-replicate successfully.

Hi all,
Not sure if this is possible or not, I have 2 virtual ESXI hosts locally and I would like to create a vcenter in an AWS EC2 instance to manage the hosts from there, is this possible? which amazon service would help me to achieve this?
II need to convert a physical Server2008R2 into a VHD-file I can run on my new Server 2016 with Hyper-V.

I try to use the good old Sysinternals DISK2VHD.EXE to convert into VHD or VHDx but it keeps failing with a non descriptive error saying: ERROR SNAPSHOTTING VOLUMES

Can anyone help me OR suggest another quick tool for converting a physical server into vhd?
Hi Expert

we have around 20 of ESXI servers with around 400 VMs

we need to buy VEEAM

my question

we are going to backup to disk let us say to NFS or CIFS and we need also to backup to tapes

but what type of tape library we have to buy if we don't want to use fiber

can we backup from our ESXI server using  VEEAM to tape without any other server to work as storage node or something like this

can we avoid using fiber interface and fiber switches

kindly advice

I recently updated Veeam Backup and Replication from 9.0 update 2 to 9.5 update 2. Since completing the update my nightly backups have started having multiple backup failures on random guest OS running Windows. I run VMware ESXi 5.5 backing up to HP StoreOnce using CIFS. There were absolutely no VSS errors prior to the upgrade to Veeam 9.5. The guest systems having issues are a mix of Windows server 2008 R2 and 2012 R2 and Windows clients 7 and 8.1. There are three different backup jobs, each has guests experiencing the issue. I also have two 2003 servers that have not experienced the issue.

I have contacted Veeam support and provided event logs from a few target systems and Veeam Backup and Replication. They have told me to contact Microsoft stating it is a VSS issue and not Veeam. Microsoft will only test one guest per incident for this which does not help resolve the issue.

I am curious if anyone else running Veeam Backup and Replication has upgraded to 9.5 and experienced these issues, if so have you been able to resolve the problem?

Also important to note, for the backups that fail on first run, some succeed on first retry, those that fail on first retry succeed on second retry. I have not had any systems that have not had a successful backup after 3 attempts, this tells me Windows systems are ok otherwise I would expect the backup to fail every time.

On Windows machines that experience the error the following event log entry is found:

Hi Experts

I have 2 Hyper-V nodes and want to setup cluster but I don't have additional centralize storage to use as cluster shared volume.

In above scenario, what is the solution to setup CSV ? Any solution ?
requirement is to setup "Failover" hyper V cluster. If one node down, another node should be able to host VM automatically.

I don't want to enable replication as my customer wants automatic failover like in Cluster. Any solution please ?

Will Storage space direct in 2016 help to meet my requirements ? (I'm still trying to understand what is Storage space direct in 2016)

We have a new 7.2 Horizon VIEW environment.  My users are getting booted after 10 hours.  I notice that's the default in the global settings for forcing a user disconnect.
I changed this setting and I had a user reboot her VM and her thin client thinking that she would not get booted after 10 hours, but it didn't work.  She got booted at ten hours on the dot.  Even the session logs shows she was booted after 10 hours.  All of my users are getting disconnected after 10 hours.
Is there another setting somewhere I can change to stop the 10 hour disconnect?
Did I miss something?
Are there any requirements for Veeam to have iSCSI connectivity for Instant Restore or back of storage?
Good day experts,
I am trying to setup a lab using a Mikrotik Virtual Firewall on WMWare Player and I am having some issues configuring the network adapters and firewall rules for internet browsing. Here is the scenario

I have a dual NIC PC with a public ip configured on one interface and a private ip configured on the other
Local area con1:
Local area con2:

In VMware Virtual Network editor I created to VNets
Vnet0:Bridged to Local area connection 1 (INTERNET)
Vnet1:Bridged to Local area network connection 2 (LAN)

In Mikrotik I configured

Local area con2 is directly connected to a unmanaged LAN switch
One Workstation (PC1) is directly connected to the LAN switch with IP and gateway

PC1 can ping (mikrotik ether2)
PC1 can ping (HOST PC- Local are con2)
PC1 cant ping public addresses

HOST PC can ping
HOST PC cab ping
HOST PC can ping any Public address

Mikrotik VM can ping
Mikrotik VM can ping any Public address

How can I get Workstation (PC1) to browse the Internet?
Is my VM networking setup correct?
What Mikrotik Firewall Filter (rules) do I need to configure to allow Internet browsing for PC1

Thanks in advance.
Currently we're running ESXi 6 and the older vShield Endpoint protection and an agentless AV solution that integrates with vShield. We're at a point where we want to re-evaluate our solution.  In the past I've looked at several solutions such as Trend, Kaspersky, and Sophos. Without mentioning the one that we had selected, I'd like to get some first-hand experience with the current crop of AV solutions that will work with VMware NSX's vShield component.

We'd prefer agentless, must work with NSX and ESXi 6.0 and 6.5, be relatively easy to install and maintain - in other words has a console that doesn't take a Phd to run - and works well as an AV solution. Please only talk about things you have tested or are currently running.
So this is strange issue that started occurring about a month ago, and I have been unable to find any useful resources online. This may or may not be related, but this started happening very soon after we migrate our VM disks to a new datastore on a new storage device in vmware. I have managed to get at least one successful backup weekly, but this is after many failed attempts with the same errors.

I originally thought this was a Backup Exec issue but after spending hours on the phone with them they declared that this is a Microsoft issue since the same problem occurred using Windows Server Backup as well.

Here are the errors occurring. This typically happens during the System State Backup or during the C: drive backup.

I have a 2012 VM running on a host 2008 server sp2.   I am having issues with the 2012 vm shutting down every few minutes.  I am seeing the following error in the hyper-v admin log.   I have tried to install integrated services.   Is there and update for 2012 integrated services running on an older host (2008 server sp2).

Integrated services version according to the registry is 6.2.9200.16384.

Data Exchange failed to connect to virtual machine 'Win2012APPS4' because the version does not match the version expected by Hyper-V (Virtual machine ID D8A5FF01-E0BE-47EF-BA5D-9017FD7CE70F). To fix this problem, remove the existing version from the guest operating system and then install the version provided with the version of Hyper-V you are using.
Hi all,
I've been trying to install ESXI 6.0 over virtualbox but I'm not able to, I just got the same message over and over again, esxi image is mounted properly, RAM is 6GB, disk is 40GB, another OS images run normally.

I know is possible to install it over virtualbox because I've seen a lot of tutorials and how-to's but mine is just not working.

PD: I'm not allowed to install vmware workstation on this pc.

have you experienced anything similar?
any advice?

i have a problem at a customer site.

i windows server 2016 running as a guest VM on a ESX 6 host works fine. but after couple of days the server cannot not be logged on.

when i tried to logon using RDP the server is not available.

when i use ESX to see the screen i got

but when i do a ctrl alt delete

it keeps spinning like

after few minutes i come back at the first screen. sometimes after 3 minutes, sometimes after 5 minutes...

When i reset the server all works fine again. But after few days, i got same problem.

any idea?
We have Microsoft System Center 2012 R2 Virtual Machine Manager  installed on a Windows Server 2012 R2 server. I was wondering if I could install that Virtual Machine Manager on Windows 10?  Basically, every time I need to connect to virtual machine via the console, I first have to remote in to that  2012 Server, run the Virtual Machine Manager Console and connect that way. I wanted to see if I could just install that on my Windows 10 machine and connect directly, similar to what I do with VMware vSphere Client.
I am trying to install Exchange 2016 on a Windows 2016 VM Server but the installation fails at step 10 of 14 with the error shown below:

My domain functional level is Server 2008 R2 and I have an Exchange 2010 server. I have performed all the pre-install steps and and prepared the Schema and AD. I tried creating a new VM and starting the installation again but got the same result. I have attached the ExchangeSetup log

The following error was generated when "$error.Clear();

Is there something I can do when I receive this error (op operating system was loaded) in Hyper-V

I do not know if the system I have imaged was UEFI or not. I also do not understand the SCSI disk term, since it is a regular SATA of which I created the VHD.
Hi Experts,

On VSphere 6 Web Client, I have removed a virtual machine from inventory, deleted the datastore it was on and have detached the storage device. But the storage device still shows in the device list.

How can I permanently remove the device, so that it no longer shows in VSphere?

The datastore is no longer needed and I want to delete the volume from the SAN once all records are removed from VSphere.
I'm trying to connect to vSphere and reboot a vm.

I can ping the ESXi host and I can connect to it via Power-Cli. If I try to connect via Vsphere client, it says




The VM at this moment is isolated and cannot connect to it.

What's the quickest way to solve the issue ?
