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'm looking to configure a VM lab where I can install separate OS's for development testing and learning but I'm not sure what is the best setup for this. I'm running Windows 10 and have a 1TB external hard drive i'm planning to use as storage for the VMs. I just need a low-key personal lab but need some direction to get this set up.

My VMs that usually works until last week., but MS update this week managed to break them with the attached error.
This error is the same for all VMs. I am using Oracle Virtual Box  5.1.14

Is there a way to make the VMS run again? if needed to upgrade do I need to run guest additions again?
When I want to create a new virtual machine I get the following error:  The portgroup for Network adapter 1, VM Network, could not be found. It has been assigned to VM Network.
I am trying to understand What Synthetic Full Backup backs up as data.
I thought it will create a full backup from storage and inject the incremental backup it has created the same day to the Full backup.

However looking at the Veeamone reporter, I see under Transferred (GB) column 48.13 GB,  it is less than the incremental one day before.

Any Veeam Expert to explain the report as shown in the screenshot below:

Thank you
Hi, I am trying to determine if I have Hyper-V manager server role configured correctly for my virtual environment.  In particular, virtual switch manager.  Why is it using an actual IP address from my network?  And is this necessary?  If not, how can I go about allowing it to reach my DHCP server on the network for the VM's that reside on the Hyper-V host server, yet not use an IP address from my very limited available IP's on my server network?

Hyper-V Host Servers:  Microsoft Windows Server 2012 R2 - Standard & DataCenter editions

Let me know if you require further details/information to answer these questions.

Thanks in advance.
I am having problems with a new Windows Server 2016 VM.  This server is a print/internal web server.  I have webroot installed on this computer and I also noticed Windows Defender is also active as well.  I have noticed several things that are odd.  For instance, I have an hosted app on this machine that will launch but immediately closes after entering the username and password.  However, on the same machine I installed Firefox and it works fine.  The software provider for this app indicates a 405 error is occurring with IE.  I have the app defined as a trusted site too.  So for now I am using Firefox to logon to the app for now.

We also use Quorum OnQ to backup our hosts.  Since this server has 1.5 million files it took a little while for the initial backup which is normal.  However, performing following backups takes 5 to 6 hours because it has to scan each file to see if changes were made to back them up or not.  So, I enabled QFiltering for this server since this feature will build a database of all the files so that it does not need to scan all files.  Once I enabled QFilter, Windows will not allow the QFilter service to start (Event ID 7000, Service Control Manager with error:  Windows cannot verify the digital signature of this file...  Also, the Qfilter service uses SquirtCopy.

So in order to get a backup of this critical server, I disabled Qfilter and the backup ran last night.  It took about 6 hours to complete.  Early this morning around 5:40am I remotely …
Hi Everyone,
I had a client who is using Windows 7 and Windows XP Mode have their Windows XP VM stop working. I am thinking the key to solving it is the Integrated Features options which is grayed out. Does anyone know how I can make these options live so I can uncheck the selected devices?

I am being tasked with moving our production web server to a "Cloud" virtual machine.   Is there a way of taking a backup of this machine and using this to load the image to the virtual?
I'm facing an issue with my Hyper-v host 1 . last couple of days when the backup job run to backup hyper-v host including virtual machines . I get below error and virtual machines lose network connectivity and loses the failover cluster communication .

"Failed to allocate VMQ for NIC B038F6F3-B1DB-48CF-9566-A98A0E7340F0--D5DAA699-7131-42C1-B895-3658D6F16959 (Friendly Name: Network Adapter) on switch 91306166-6B98-498C-B029-D552838FCD61 (Friendly Name: External). Reason - Maximum number of VMQs supported on the Protocol NIC is exceeded. Status = Insufficient system resources exist to complete the API. "

usually the virtual machines can be reached on network in 15 minutes . but its been 8 hours a mailbox server virtual machine is not accessible through network and i have tried accessing through hyper-v manager but its unresponsive .even i tried shutting down from hyper-v manager but throws me error. Is there any way to access the unresponsive mailbox virtual machine other than turning it off from hyper-v manager at the moment make the mailbox server up.
I'm desperately waiting for a help .
Thanks in advance.

I have a 2012r2 Windows, hyper-V VM running on a dell r320 server that I am going to move it to a dell r720 server.  Can I simply export the VM from the r320 and import it on the r720, change the NIC and fire it up?
We have a 2012 R2 Host Server that had been backing up 100% Using Altaro Software. Now we are getting failed backups. We have found that the "Microsoft Hyper-V VSS Writer" keeps failing. During our investigations we have found that we appear to have a corrupt file (Catsrvut.dll) being part of the COM process we have tried to fix the corruption. The error message is below. If we just run "SFC /SCANNOW" the results say everything is fine but it clearly is not if you runf SCANFILE. Running this command also comes back with a clean report "DISM.exe /Online /Cleanup-image /Restorehealth"

It seems that this file is not easy to fix so we are asking for some assistance to resolve this corruption. Thanks in advance guys.

"C:\Windows\system32>sfc /scanfile=c:\windows\system32\catsrvut.dll

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not

Hi Everyone,
I have a client with a Windows XP VM (Microsoft Windows XP Compatibility Utility) running on a Windows 7 Machine. I need to move it to another Windows 7 machine.
I have followed the steps outlined here https://www.hanselman.com/blog/TransferringMovingAVHDFromWindowsVirtualPCWindowsXPModeToAnotherComputer.aspx

Specifically I merged the parent and differential changes into a single file on a flash drive and named it the same as the original parent file. I then took the combined file and placed it on the new computer here: C:\Program Files\Windows XP Mode\ replacing the Windows XP Mode base.vhd file created when I installed the Windows XP Mode VM machine software.

I then started the Windows XP by double clicking the Windows XP icon here: C:\Users\(user name)\Virtual Machines, got an error and immediately the Windows XP icon went missing leaving nothing in the folder.

What did I miss?

We originally setup small lab environment for Terminal Services on Server 2012R2 in a Hyper V.  1 Dc, 1 TS. and it was working.

Then I exported the pair of VM and gave it to another tech to work on but when he was trying to setup the TS, he got an error saying "Hardware assisted virtualization is not present"

What would be the reason it won't work now? does the VM need to be started from scratch?

Ok, so i have done V2V migration using Veeam Quick Migration / Veeam resotre.
no matter, what i do i get the attached error.
can anyone shed any light on this, is it something to do with Vmware version or incoparible H/w
i have tried :
1. sfc /scannow
2. chkdsk
Running Hyper V host on a Win 2016 server with 2 VMs that are allowed with the licensing. I need to 'replace' one of my VMs temporarily, as part of my move from 2008 SBS to Exchange 2016 & wonder if it's possible to remove one of my VMs, add another for the hop to exchange 2013, then remove that one when finished & restore (or import) the original one back in?
I have a Linux server that is constantly maxing out CPU usage on my daily SolarWinds monitoring report. I checked the box out and it is part of our network team. They call it a "Radius/Tacacs and NAC. Networking asked me if I could just simply add my CPUs, so I checked out the configuration and it is configured with 6 virtual sockets all single core.
I doubt it is as simple as just adding CPUs. If I had set up this server I would have probably done 2 slots/2 core per slot, but that is only because that is how I have seen other virtual Linux boxes configured in the past. Can someone give me some suggestions and how I can prevent CPU from maxing out on this device? I know this is kind of vague but any trouble shooting suggestions would be welcome. Also does adding CPUs affect licensing?
Hi All,

I'm in the process of migrating an old file server to a new file server.  They both sit on the same SAN volume and are both thin provisioned.

I though as the data moved across it would release the space.  But this doesn't seem to be the case.

Is there a way to release unused thin provisioned space?

Many thanks
Hi everyone,

I have virtualized a Windows 2003 server into an Hyper-V environment with Disk2VHD. In the physical server I am able to do this:
I am able to see the content of netlogon.

When I do that in the virtual system (exact 100% the same Windows / setting / etc. offcourse) I get:
\\servername\netlogon is not accessible. You might not have the right permissions for this network location. Contact system administrator.

I do not get this permissions error since I cloned the physical to virtual, so everything should be exactly the same.

Automating Your MSP Business
Automating Your MSP Business

The road to profitability.
Delivering superior services is key to ensuring customer satisfaction and the consequent long-term relationships that enable MSPs to lock in predictable, recurring revenue. What's the best way to deliver superior service? One word: automation.

Background Information:

- We have two separate but identical sites (Production and Disaster Recovery)
- Both sites will have their own infrastructure of 3x servers, 2x iSCSI switches, and 1x SAN
- Data from production site will be replicated to DR site quite regularly (may be real-time)
- Sites utilize VMware ESXi/vSphere 6.5 and will have Acceleration Kits

We are in the process of an infrastructure upgrade, and am in the planning phase of implementation.  Once we have all of the above fully implemented, how can I configure a proper fail over and fail back configuration?  I am pretty sure I may be able to configure High Availability on a single site for a failure of a single host; would it be possible to configure some type of fail over should a disaster completely bring down an entire site (if building hosting production equipment burns down)?

Is it even possible to utilize VMware High Availability to fail over to another site/SAN?  If it was a temporary failover (power at production site is lost, then comes back), would there be an automatic fail back?

Can I use this method to temporarily take down a site for maintenance while having no impact to end users?

Thank you in advance for any assistance provided.
In ESX 6.5, is there a way to prevent or at least make it more difficult for a VM to be powered on? I have some VMs that have moved to another vCenter, but am required to leave the originals behind for now. Since these are exact copies there are risks of network conflicts if someone accidentally powers them on.

All my searches come back with how to disable power off in Windows, but not the VM itself.

I  need to migrate a VM to a new ESXi host. The VM hosts  software which has a license key tied to the MAC address . The new license key will take  24 hours  re-generate - the software cannot be offline that long..

The advice from the Vendor is to replicate the VM to the new host, power-down the existing VM, power-on new VM to get the new 'RegCode' to submit for license generation. Then reverse.

Once the new license code has been generated - power-up the new replicate, enter the new license code..

Is there a way to power-up the replicated VM to get the  'RegCode' without having to power-down the live VM to avoid IP conflicts? The new host is connected to the same networks  and several VM's are make use of the NICS.

This is the idea:


*I buy a HP Microserver Gen10 x3421 with 16GB for about 600 Euro (what is the price of a Synology DS 918+ with 12 GB ram), it will replace my DS414 Synology (4 harddisks)

*Microserver has no ILO, so I would attach it to TV in living room (Microserver would be really silent I heard,

So I can use TV not only for configuring HP Microserver but also to play movies, f.e. which are offered on webpages (was already looking to do that)

*configure Micoserver with RAID 5 (maybe attach SD card instead of cd rom but there is no option to attach it(?))

*install Windows 2016 server, but with VMWare Workstation, this way I can play with both hypervisors (disable VMWare workstation if I would want to play with Hyper-V)

*a (Windows 2016) server has 3 sessions so I could easily connect remotely without impacting somebody who is watching tv

*install XPENology on VMWare Workstation (there is no XPEnology 6.1 for hyper-v) and create a big volume on RAID5 just for my data, guess that would be ntfs

*vmware workstation can be started when windows start and xpenology can also automatically start
*I recover a full backup from my synology to this XPENology and I should be good to go
*3 main users at home/remote: forget any config on local machine(s), they just connect to this server and all config is there :-)
(1 console session for tv, 2 rdp sessions)
*any update from XPEnology, I can test in a new vm before updating my "main …
So, i have my 2 virtual ESXi servers deployed to VMware and then install vSphere and after some earlier problems get everything up and running. I had 4 vms running in the 2 node cluster in total.
I noted my 2 ESXi nodes were only allocated 8GB, so i downed everything, upgrade RAM to 12GB and turned ESXi servers back on.
Now my problem. vSphere shoed a continual disconnected state even after trying to reconnect. I reset management network and agents of ESXi(s). I then removed the hosts and added them back, but got an error both times. The VMware workstation and vSphere installs are on the same physical host. From the host, and so the vSphere server i can ping both ESXi hosts no problem. But cannot add them to vSphere. I deleted the cluster and data center, rebooted, recreated data center and cluster - you guessed it- same fault. I simply cannot add the hosts to vSphere and need some help.

The error is
Call "Datacenter.QueryConnectionInfo" for object "New Datacenter" on vCenter Server "hyperv" failed. and i get the error that i have uploaded. Thank you.
Good morning,

I am currently trying to perform vmotion of one of my vm but when selecting the destination host, it tells me the following message:

Currently connected network interface 'Network adapter 1' uses network 'dSW-Front-Prod', which is not accessible.

It prevents me from doing the vmotion, any suggestion regarding the message.

Stay tuned to your comments.
