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.

I am faced with an activation problem.  Microsoft support is not available today (sunday), so I'm asking you guys for help.
A VM running Windows 10 Pro was previously operated on Hyper-V.  I used the vSphere Converter Standalone to migrate it to VMware.  Now it is asking for activation.
There is no "just activate it"-button to press - I only have the option to go to Microsoft Store or to change the product key.

This is my issue:
I cannot klick on "change product key".  Or rather:  I can click on it, but nothing happens.

How can I change the product key?

VMs are slow to load and operate, eg: 10 minutes to login & get automatic services running. Launching Server Manager or EventViewer takes 2-3 minutes, and app installs take 30+ min. While launching, no apparent bottlenecks in CPU/Memory/Disk/Network as shown below. This is true for any VM on this host. Please forgive the extensive post; I wanted to provide complete info.

I’ve applied every VMware performance tweak I’ve found (below) and all typical Performance Monitor counters seem normal while launching, however still the VM crawls. I understand that this isn’t high-end lab hardware, but while launching, the disk is often 99% active with read/write only 0-5MB/s, when I’d expect it should be very busy reading. I’ve tested raw file-transfer as fast at 130MB/s, so why is disk transfer near-zero when launching? Doesn’t seem to be a nesting issue; I see similar behavior when launching the parent ESXi VM in Workstation.

Environment: Nested VMware lab
Hardware: HP Pavilion AMD FX Six-Core proc @ 3.3GHZ, 32GB RAM, 3TB HDD 7200RPM Seagate ST3000DM001
Parent OS: Windows 10 Pro 64bit
Host: VMware Workstation Pro 14 host running ESXi 6.5
VM:   Win2016 1607 DC on 4 vCPU, 8GB RAM, 60GB storage

Performance Monitoring / Diags while launching VMs:
VMware tools: installed
VT: enabled
Host CPU:  5-20% with only momentary peaks to 90%
Host Memory: 14GB avail (4GB avail on VM)
Host Disk:
- Disk Activity: Between 10-99%
- Read: Mostly 0-5MB/s; seldom, brief …
If I don't click "Power on VM after restoring when I fall back the replicas to the production environment, how can I  start the VM in the production later  ? Should I shut down the replicas  and start the VM manually ?

Will the job under Replicas job will still shown as "Active" in this case ? How should  i handle this job ?

VMs in environment showing a very high vMotion precopystun time. Recommendation for healthy environment should be below 500ms or less but precopystun time over 900ms in environment. What can be implemented to reduce this time, can anyone confirm?

When create backup / replication job on File and Exchange sever, should I click "Enable applicaiton-aware processing"  on Veeam Backup & Replication 9.0 ?


I'm trying to find a clean step by step guide on how to migrate VMware VM's to Azure. I've been looking at a few sites but they each seem to differ a little. From what I gather I need to:

1. Use the Virtual Machine converter to convert the vmdk to a hyper V disk
2. Use hyper V manager to boot the machine and install the drivers
3. Upload a management certificate to my azure subscription

I have not done any of the above steps yet as i wanted to verify or see if their is an easier way.
Need to build a brand new from scratch 2 host failover cluster with Server 2016. Only a DC and F&P server are needed. There is no domain in existence currently. Therefore what would be the best order of steps to do this?
The VMs are on shared storage.

e.g. this did not work.
Build host 1 with Hyper-V
Add a VM as a DC and create new domain.
Add host 1 into the new domain.
Build host 2 with Hyper V
Add host 2 into the domain.
Add the Fail over clustering to each host and configure the cluster (including building the F&P VM) using the domain.

I have done the above as a test with the DC being added as a highly available server into the cluster.
Host 1 'owns' it. As soon as host one is forcefully switched off, the domain shuts down with the DC on host 1 and the cluster disappears from the Failover Cluster Management console of host 2.

Should i have 2 independent DCs (one per host) instead so that when one dies the other keeps the cluster alive?

Is there a best practice?
I have a NetApp FAS 2520 running OnTAP 7 Mode and use it for my Hyper-V environment (storage for clustered Hyper-V hosts). I currently have a LUN mapped as a Cluster Shared Volume from the NetApp via iSCSI for my VHD and VM files. I have numerous separate LUNs mapped as volumes for my network shares (user files), SQL DBs and logs, SCCM repositories, etc. as I was guided by NetApp that this is the best way to set this up, likely because the initial thought was to use their backup and replication solution which we’re not using now.

I have recently switched my backup software to VEEAM. In using VEEAM, any of these VMs I’m backing up that have a LUN mapped to them for storage (file server, SQL server, etc.) need to use an add-on Windows Agent because of the non-virtual disk storage used.

So I’m wondering if there’s any negative impact in creating virtual disks in place of those mapped LUNs, moving the data to those, and then mapping those virtual disks as volumes so my VMs have all virtual storage and no longer need the VEEAM Windows Agent installed. Any thoughts on pros or cons of setting it up this way?

I added a large 3TB VM to the Veeam backup job and ran it over the weekend. It started out processing fairly quickly but gradually got slower.  I looked at the esxi console and there was the question about the redo log file being corrupt.  CAlled Veeam support who suggested that to stop the job and manually consolidate the disks, but I cant do that - the option is grayed out.  

I havent clicked on the OK button to the above question as I fear the VM will boot.

Any advice?
Dear Experts, we are using Veeam B&R 8.0 to backup VMs to a NAS. But the storage's size was consumed very fast. Please see the attached pictures for the settings of restore points and VM retention in Veeam.

In the rest picture, you can see we have some .vib (incremental) and .vbk (full) backup files. Questions are:

1. If we setup the restore points to 15, why did not Veeam delete backup files before October 1st automatically? Is there any setting which we can config to achieve that?

2. Can we delete some backup files manually?

Many thanks in advance!

Server OS: Server 2008 R2 Enterprise
Running Software: Microsoft SQL 2005 & Adobe Cold Fusion 9

I have a server that is having "memory issues".  What's happening is when I look in Task Manager, I see that the memory usage is running at 95%.  Since it's a virtual machine (VMWare), I increased the RAM by 4GB (so now it's at 24GB total).  After booting up, I notice that it's running at 97% again.  When I look at the Processes tab, I see that JRun.exe (Cold Fusion) is taking up 4.3GB and sqlserv.exe (SQL) is taking up 2.4GB.  The other processes, when added up, don't come anywhere near 24GB.  So what is using up all of the memory and why isn't displayed in Task Manager?
I checked my pagefile and noticed that the C: drive is set to "System Managed" and the page file on root of the C drive is a 24GB in size.  Does that have anything to do with it?

I powered off guest OS (Windows 2008 R2) before acquiring snapshot.
After reboot, I installed some upgrades and all went ok.
Now I would like to remove snapshot.
Should I first power off again that VM, or can I proceed with VM running?
Thank you
ESXi: 6.0
Dear Experts

I plan first to clone the VM from Hyper-v to ESXi 6.0 (via VMware converter - cold migration) to new HW and then I need to increase the VM's C-drive disk space. Best methods to do that?
I am setting up a new Hyper V host with Windows 2016 (GUI mode).
The VM will be a very heavy network user (CAD system for 10 engineers)
I have 5 NICs available on the system.
How to I set up the NIC teaming to get the best performance ? On the Host ? on the VM ? on both ?
My client has their DNS configured to the local virtual machine.  I was curious if DNS is configured on the Virtual machine or in the vsphere client?  If the server crashes nothing works, was wanting to add a secondary dns address just something generic like googles, just didn't know if I needed to configure that in vsphere, or on the virtual machine Windows server?
Failed to start the virtual machine.
Module DiskEarly power on failed.
Cannot open the disk '/vmfs/volumes/59b85604-3e73e872-6bac-5cf3fc4c10a8/kali-linux/Kali-Linux-2017.2-vm-amd64.vmdk' or one of the snapshot disks it depends on.
The system cannot find the file specified
VMware ESX cannot find the virtual disk "/vmfs/volumes/59b85604-3e73e872-6bac-5cf3fc4c10a8/kali-linux/Kali-Linux-2017.2-vm-amd64.vmdk". Verify the path is valid and try again.

I need to bitlocker my W10 but have a VHDX on it to which I boot (mounted VHDX, added it to start menu) sometimes (different W10).
How can I bitocker the W10 AND still boot my VHDX which is on this bitlockered disk WITHOUT creating a different partition?

My Veeam backup server failed.
Would like to reinstall and make it up.
Appreciate if someone can guide how to recover a failed Veam server.
Backup files are safe in NAS.

Now we r running without a backup solution.
An error was received from the ESX host while powering on VM VEEAM.
Failed to start the virtual machine.
Module Disk power on failed.
Cannot open the disk '/vmfs/volumes/56f421ed-263be15c-c931-e435c87f06f4/VEEAM/VEEAM-000001.vmdk' or one of the snapshot disks it depends on.

I deleted some LUNs to recreate a better LUN. Veeam was not installed in SAN it was on local datastore.
I didnt delete the database or VMDK still I cant start the VM.

Server name is VEEAM.
If anyone can guide me how to fix this and boot would be great.

Honored Experts

After a hard struggle I have succeeded in converting a physical Server 2008R2 to a VM on my Server 2016.

My problem is, that I can not use the mouse in the remote desktop session.
I think this has something to do with the Integration Service, but if I check properties of the vm all Integration services is enabled.
Any suggestions? :-)
Looking at changing my current backup regimes, at the moment I have two sites that have two separate backup solutions.

Site 1.  All VMware Servers which get backed up to Dell SAN Storage via VEEAM which then gets replicated off-site to another Dell SAN which sits in a Data Centre and has a site to site leased line.

Site 2.  Mix of VMware Servers and Physical Servers which all get backed up to HP via MPLS and then to HP

What I would like to do is set a new backup solution that will backup to onsite SAN then replicate to the cloud for both sites.

I know this is a wide subject but my only stipulation is that I can backup virtual and physical servers using the same software and cloud storage platform.

Hi all,

We've got 2 servers that we're putting RDS servers onto (one on each) and so we want a good performance on the RDS as we're moving everyone to it so we've ordered 4 x SSD drives (obviously 2 on each server) which i WAS going to re-install the Hyper V OS onto and then put the RDS VM's on the normal NLS drives but someone mentioned that it's better to keep the OS of the Hyper V host on the NLS drives (mechanical) and put only the VHDX's of the RDS servers on the SSD's ?
Is this the best practice ?
We have checked on below Lenovo website and found  Windows 2016 is not supported on  X3850-X5.


However as per Vmware compatibility guide, vmware ESXi 6.0 is supported on X3850-X5 and Windows 2016 is supported on ESXi 6.0. but we are not sure if Windows 2016 as a guest os (VM) will support on ESXi  6.0 hosted on  Lenovo X3850-X5 servers.
Good evening dear,

Is VDP 6.1.4 compatible with Vcenter 5.5 upgrade 3?

Stay tuned to your comments.

I'm setting a new Dell PowerEdge T430 server that came pre-loaded with VMware ESXi 6.5.  It has an internal RD1000 removable drive bay.  My plans are to use the RD1000 with (5) removable 1TB cartridges to do backups on.  Is it possible for the RD1000 to show up as a drive in a Windows 10 VM?  If so how?
