Microsoft Virtual Server Help & Support

Simple question: I have been testing Hyper-V Server 2019 (the free barebone) and I cannot create more then 128 vm and I search and found no information that mentionne there is a limitation for that. They all say that as long has I have RAM I am fine and I have loads of them.
If this is the limitation, I will need to go back to Proxmox....

Thanks for the info

VM Configuration files in External USB HD

Hi,

I have HyperV Server 2016. Virtual hard disks and configuration files reside in the following folders:

E:\HyperV\Configuration\Virtual Machines
E:\HyperV\Virtual Hard Disks

Recently I restored a virtual machine from an external USB hard drive (managed by Windows Server Backup) in Windows Server Backup. As seen in the screenshots, I restored the VM to an alternate location which is F drive (another external USB hard drive) . My intention was to restore VHDX files for the VM and I thought I could do that by using Windows Server Backup. But the problem was:
(1) Instead of selecting "Files and folders" in Select Recovery Type screen, I chose "Hyper-V.
(2) In "Select Items to Recover" option screen, I ticked "VPN" VM and "Host components".

After restore job was finished, I realized that the VPN VM was running from the F drive (external USB hard drive).
So I shut down the VPN VM and got into "Settings" for VM and changed the virtual hard drive location from "F:\Restore\VPN\E_\HyperV" to "E:\HyperV\Virtual Hard Disks".
Then I realized that Smart Paging File Location has also changed to F:\Restore\VPN\E_\HyperV\Configuration\Virtual Machines. In that folder, I saw 91A13DBB-A705-4337-8929-6F46E2023512.vmcx, 91A13DBB-A705-4337-8929-6F46E2023512.VMRS along with 91A13DBB-A705-4337-8929-6F46E2023512 folder. At the same time, those files have been removed from their original …

Running Windows Server 2008 R2 as a Hyper-V host for a couple of VM Servers. For a new Backup scenario I need a program that will not work on 2008 R2. Can an 'in-place,' upgrade to Server 2016 be done? Will I need updated licenses to keep the two VM Servers I am currently using?

I just setup a 2019 standard server and created the first VM guest. When I go to connect to that guest in hyper-v manager, the display window is larger than the screen. Both the host and guest instance are set for 1024x768. I do not have the option to grab any of the borders of the window to drag and make the window smaller. This should be straight forward.

Hello,

I was told, when we first purchased a virtual environment and had our servers moved to virtual using VMware 6.7, that the VMs and HOSTS could be patched/updated without any outages for the users.

From what I am reading, the HOSTS can be patched without any outages if I move all the VMs (while they are running???) on 1 HOST to another. Then I can patch the HOST that does not have any VMs attached???

Also, the 'patching/updating' the VM is actually the VMware Client Tools that can be updated while the VM is functioning???

Is this correct?
Is there any way that I can patch ...say.... a Windows 2016 virtual Operating System without any outage if the Microsoft OS patch requires a reboot?

we have single windows 2012r2 server with 2 hyperv servers running on it.

our raid is getting rather full, and wanted to relocate one of the servers onto a new 1.2tb drive we have just added to the server. we can then expand the hyperv volume size on the remaining server, to gives us some more room.

we intend to add another raid so we can expand our storage, but for the moment, we are hoping the extra drive will ease our constraint.

my question is what is the best way of relocating a vm? i have never done this before, and as it is a live production server, wanted to make sure i did it the right way.

any detailed instructions on this progress would be very much appreciated.

many thanks

I have two 2012 R2 Servers joined to a domain and running HyperV. Both Servers are connected to a SAN via iSCSI and so there are about 8 mapped drives on each server using iSCSI initiators. The previous admin had replication going from Server A to Server B. The VM's have their storage in multiple mapped drives. We upgraded the Backup SAN with bigger drives. The previous Admin setup Replication between the two and then quit.

We failed the HyperV Replication over to the Backup Server and SAN. Everything came up fine, however when we upgraded the Primary SAN and went to set the Replication back up I can't figure out how he did it. When you set the Replication it has a field that says "Specify the default location to store the Replica Files:" under the Authorization and storage section. All of the iSCSI connections have different drive letters.

If I start a replication of VM1 and use it's storage drive letter of H, it comes over fine. But when I try to replicate VM2 with drive letter G, it goes to H as well and the VM's fill up one drive instead of going to their own drive letters and shares.

How can I set this up so they all replicate to their own storage on the iSCSI of the backup Host?

Dear Experts,
Creating a disk partition via disk management utility on virtual machine that runs on hyper visor is same as the the physical machine???? Last time I created the partition of VM that run on hyper v. I found the the new partition created on my physical machine automatically. It was little confusing. Can you throw some light on this issue??

VM is windows server 2016.

Many thanks for your valuable advice in advance

How do I remove the snapshots on a hyper-v. Can not edit the disk because- Edit is not available because checkpoints exist for this virtual machine.

Hard drive full with a VHD that is not the size of the hard drive!
I have a 446gb hdd with one file on it - a 142gb VHD.
But the drive reports only 61gb of free space!

Where has my disk space gone? I have searched for ADS, and the recycle bin is empty.

Hi,

I accidently created a snapshot on the VM "FT1" and there are two problems:
(1) Every so many seconds, when I open this VM in Hyper-V manager, it goes to "pause" state showing the screen in shaded color. When I start it, it goes back to shaded/pause state.
(2) Now I am getting "Out of Disk" message on my Hyper-V server.

I did not intend to create a snapshot at all. I was expecting a snapshot manager screen as I chose "snapshot". But I think it is trying to create a snapshot and the server ran out of space. It seems that the logical thing to do is to cancel "snapshot creation process" because there is no hard drive space for the snapshot to be created in the first place, delete the temporary file "FT1_2481848F-1B1E-4667-A1A2-985A4E532138.avhdx"(18.9GB), and restart the "FT1" VM.

What should I do?

** I forgot to mention that I was trying to shut down the VM, but that is even stuck.

My primary AD server (and DNS) is a physical machine (Server 2008R2), while my secondary AD server (and secondary DNS) is a hyper-v virtual machine.
My primary server I back up each day, but the secondary vm is backed up as a hyper-v image from 3 months ago.
I lost the virtual secondary server (theft of the host server), and would like to restore (import) the old hyper-v image on the new host server.

If I import the old hyper-v image of the secondary server onto the new host hyper-v server, will it run okay? Or will the new host hardware be a problem for the virtual AD server? I have already imported another non Active Directory vm image to the new host hardware, so I know the hardware is compatible, just I am unsure about AD.
Also, I assume the secondary server, once connected will automatically synchronise with the primary server?

We recently upgraded our SCCM clients (Configuration Manager) to 5.00.8634.1814.

We did this after upgrading the site to 1802.

After the upgrade all of the icons in Software Center are wacked out. Prior to the upgrade, something was taking different sized icons and make them automatically appear the same.

In the new version, this functionality works in the List View option - all icons appear the same size regardless of their size. In Tile View, which everyone uses, this is not the case. The icons are not being adjusted for the view.

Has anyone else noted this issue? Is there a setting somewhere I can click to resize?

I hope so. So far it's that or I have to resize them all manually.

SIP and Primary SMTP domains do not match. Skype for Business 2015 client displays EWS not deployed.
Hello, I have an Exchange 2007 and Skype for Business 2015 Server on-premise solution deployed.
Originally, functioning fine with SAN certs using <company>.org domain for required certs on mail server and SfB 2015 Standard Edition solution (Standard, Edge and WAP servers).
Primary SMTP domain was <longcompanyname>.com (domain NOT included in the SAN certs) and everything functioned fine including Conversation History and Calendar synch between Outlook (2007-2013) and Skype for Business 2015 client.
Fast forward a few years and....
New domain purchased and Primary SMTP for each user changed to <shortcompanyname>.com
NOW, Conversation History and Calendar do NOT synch with Outlook anymore.
Research appeared to state I can have this circumstance without issue after running 'Set-CsClientPolicy -DisableEmailComparisonCheck $true'
Ran the powershell command on the SfB Standard Edition server, rebooted test client and SfB solution. STill Outlook Integration Error and EWS not deployed in SfB client Configuration info.
Advice?

A client of mine wants the Direct Access role to be installed within a Server 2016 Hyper-V virtual machine.

I have already found instructions for setting up Direct Access but these guides don't include any instructions on how to set up the Hyper-V networking to support installing Direct Access within a Server 2016 Hyper-V virtual machine.

Please provide me with the instructions for installing Direct Access including setting up the Hyper-V virtual machine networking that is necessary for installing Direct Access within a Hyper-V virtual machine.

Direct Access will be installed on a server that has 4 physical RJ network ports.

We currently have SBS2011 and We want to move to Server 2016 as our DC with Exchange 2016.
We don't need any advice for setting-up Server 2016 as a DC or Exchange 2016 - however

Should we-

Setup and configure Server 2016 as a DC on physical hardware - install the Hyper-V element and setup a VM to run Exchange 2016 (within the DC environment)?
OR
Do we setup the host OS (Server 2016) on Physical hardware and install the Hyper-V element - THEN setup 2 VM's - one as the DC and the other as Exchange.

Which is the best configuration please.
Thank you
Paul

I have a Hyper-V base server that has a total of 24 processors.

Is it possible to assign more than 24 total virtual processors among the Hyper-V virtual machines?

In other words, can the virtual machines share virtual processors?

Hyper-V Storage Recommendation for small enterprise required.

I have a customer that is a 25 seat accounting practice. Currently they have a server that is 4 years old, dual Xeon CPUs, 72GB of RAM. Storage is a RAID 6 array of 8 15K 300GB SAS hard disks. There are 2 years remaining on the warranty. The server is a Windows 2012 Hyper-V host. There are 3VMs, a DC, a file server and a RemoteApp server. The server provides more than adequate compute resources but is running out of storage space. One of the file server volumes has already been moved to a Synology NAS connected via iSCSI. Even with that, storage on the server is becoming severely constrained. Storage requirements are only going to grow as the client is moving towards "paperless" operation.

I don't know much about storing VMs outside of the box that they are hosted on, but it seems attractive to move the virtual disks to some sort of network based storage. Easily scalable storage, and when the time comes the ability to replace the Hyper-V host hardware and simply migrate the VMs without disturbing the VHDs. For a smaller organization like this it seems (from my limited research) that a true SAN is not going to be financially viable. Is it feasible to use NAS boxes to store VMs or am I going to be better off just recommending replacing the entire server?

DR is handled by a 4TB Datto Siris, so building a multi node cluster really isn't necessary either IMHO. I know there are some small scale …

Networking in Virtual Machine Manager

Hi, I am looking to use Virtual Machine Manager in my domain.

I am setting up logical switches etc, and currently I have it set up as follows.

3x Logical Switches - Client, Storage and Management.

The management Logical switch has 2 uplinks, one for cluster comms and the other for host management. The storage has 1 uplink for storage and the Client has no uplink, as I map clients to it.

Now, each of my servers have 6 network connections, 2x 10GB and 4x 1GB. Currently I create the storage virtual switch with the 2 x 10GB adapters. I use port 1+3 from the 1GB for Management and port 2+4 for the client.

This setup works well. I have created a cluster in VMM and it all seems to work without issue.

However..... I have been thinking that I am wasting bandwidth on my 4x 1GB ports, as host management / client communications use hardly any badwidth but I have 4GB assigned to them.

I tried adding the Client uplink to my Management Switch, but then this also creates the connection on the local host which takes up an address in the address pool etc.

Is it possible for me to share the connection across all 4 1GB connections and have the setup how I want?

Thanks in advance for any help.

Hello,
We have a Hyper-V cluster consisting of 3 hosts sharing 5 VMs. The disks are part of an iSCSI storage. One of our servers "server1" has its drive D on:
C:\ClusterStorage\Volume1\HyperV\server1\Virtual Hard Disks\server1\DATA_5F06292E-D0FD-4D21-AD25-DFF18040CFD7.avhdx
We traced Volume1 to Cluster Disk 2 which has 6.8TB with 1.5TB free.

Is expanding server1 drive D volume the same as if this HyperV host was a stand alone?

Should I follow these steps here or are there any special consideration for a Hyper-V cluster?

https://redmondmag.com/articles/2016/01/04/expand-vm-storage-capacity.aspx

Also, I noticed some VMs have a lot of checkpoints, which are only visible from Hyper-V manager. Can I safely remove those? I am assuming they are tight up to our backup software Altaro which is not used anymore.

Many thanks for your help.

I have a dc and i have used VMware converter standalone to get my secondary dc and mail server online in vmware workstation. I am able to ping mail server and secondary dc.

Problem: When I create a vm for my primary DC i get the following error when it is booted in vmware workstation 0xc00002e2

What can i do to fix this.

I have tried using other tools like disk2vhd as well and ls it works fine in hyperv without any errors. If i install hyperv on the same machine i get errors when vm's load up in vmware

I have also used shadow protect to backup but it was unable to boot on vmware and gave the same error 0xc00002e2

I have also tried the following

According to Microsoft's documentation, here: https://docs.microsoft.com/en-us/system-center/orchestrator/get-network-adapter?view=sc-orch-2016 I should have a filter called "VM ID", however I am missing this and several others (see screenshot)...
