Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

We have upgraded our virtual environment from Hyper to VMWare. Both environments consist of a SAN and 2 host. We were able to successfully migrate all of our vm's with the exception of two of our SQL servers. One of the SQL server is apart of our SharePoint environment. After I shut the SQL server down in Hyper-V and power on the SQL server in VM and lauch our SharePoint site, I get the following error:

Recover Cluster Event Entries in Failover Cluster Manager:

Is there a way to recover the Cluster Events after the Reset Recent Events option is triggered?

  • Server 1 in Cluster A
  • Server 1 is evicted and updated
  • Server 1 Re-Configured joined to domain and reintroduced to cluster

In this Scenario, there should be several events.

  • Evict Event
  • Join cluster Event

Are these logs stored anywhere other than on Server 1 and the failover-cluster Manager?
Windows Server 2016 Standard install questions.

I have a client that currently has an SBS 2011 Standard installation (10 users) that needs to be replaced.  Initially I was looking at a physical server (Dell T330 with Single CPU - 4 Cores, 32Gbs of RAM) with Windows Server 2016 Essentials.  A straight forward basic install.  O365 Exchange On-Line Plans I and II will take care of hosting their mailboxes.

However, this client now has a remote office with two or three users. They currently have one user that remotes into an existing computer to access applications (Needles database, Quickbooks, company files, local Exchange mailbox.

So, I was thinking of acquiring MS RDP CALS (5 licenses).  However, the server would be a Hyper-V server with two VMs (1 VM for AD, company file storage, and hosting the Needles and QB databases), and the second VM would serve as an RDP Server with (5) licenses.

I do like Windows Server 2016 Essentials mainly for the built-in Remote Anywhere Access and 25 free CALs, and would still like to install it as a VM.

1. So, I need to know can Windows Server 2016 Standard allow installing Windows Server 2016 Essentials as a VM with the Standard license, or will an additional Windows Server 2016 Essentials license need to be acquired.

I am thinking a Windows Server 2016 Standard license allows installing a downgraded VM as an Essentials server, but I am not entirely sure.

2. Since the server will be purchased with (1) Intel E-3-1240 v5 …
Hi experts.

I have a HPE C7000 Blade chassis with 4 BL460C Gen 8 blades in.  I have 2 HP VC FlexFabric 10Gb/24-port Modules in the Interconnect bays.  I have the Virtual connect configured like this:VC.PNG.

The blades are running Server 2016 Datacenter.  The VLANs 100 & 210 are both storage iSCSI connections.  VLAN30 is the host management lan.  The multiple networks include VLAN 10 for the VMs management, as well as VLANS for live migration and CSV.

On the host, we run a PS script:

We are going to be purchasing a new server for one of our clients.
as far as disk space I know what i need.

When it comes to administering CPU and memory I'm not too sure what i need.

We will have 3 guest Machines in hyper v.
1. DC only
2, RDP server with up to 20 clients. Running office 2016 , Adobe, and SQL client software.
3 File server.

Does anyone know how to calculate what i might need or have a requirements table to go by?
I have a hyper v server that has the error: "There are no logon servers currently available." Any suggestions on how to get into the server and resolve this issue would be appreciated.

In a Hyper-v environment I have a VM (we'll call it B, Host is A).  A cannot ping B and B cannot ping A.  3 other VMs work fine. If I remove the network adapter from B and reboot, then shutdown and add the adapter back it will work for a minute or two then quit. No Firewalls are turned on. No Anti-virus involved. Event log looks clean. I want to back up the files from B to a hard drive on A and it won't work because of this issue. B is a server with MAS accounting software on it so its not just easy to create a new VM but I can if necessary.
Why is my physical Windows Server host port scanning a virtual server, and how can I stop it doing so unnecessarily?
I have an issue with SAN Storage and Hyper-V, i run my Virtual Machine on IDE Controller and as per MIcrosoft VM SQL best Practice they informed its better to run the VM on Hyper-V SCASI controller now when i tried to move from IDE to SCASI the VM not booting and windows not start.

Hyper-V Windows 2012 (not R2)

What should i do?
Task Manager CPU 99% but list adds up to 14.3%
I've seen this type of difference in task manager before, but not such a large difference.
Investigating with ProcessExplorer has never yielded me more information.

This is a 2012 [r1] VM-Guest Server with RDS role (10 desktops + SQL), running on 2012 [r1] Hyper-V Host.   Its no secret this server is under-powered, but while I've advised of this the customer keeps coming back with "why is it slow"   Grrhhhh...   I'd like to find evidence that is more specific to backup my argument, something I can show in pretty colors that they might grasp as the truth.

How can I further my understanding of why the the list isn't adding up to 100% ?

I have  2 win server 2012 R2 server cluster and 3 VM server on this.

I am not able activate windows by using  slmgr /ipk DBGBW-NPF86-BJVTX-K3WKJ-MTB6V command.

1 Server has been activated but remaining 2 not.
Hello to all,

I have a very strange issue with m Remote Desktop Servers,

I have 4 Remote Desktop Servers and last month randomly and with frequency 2 times a week the Remote Desktop server loose network connectivity.

The strange is that users are conencted but can't open any application that are in network.

This is the first problem.

Because we use roaming profiles/folder redirection after 1,2 minutes users hang.

To resolve the problem from the HYPER-V IN Virtual Machine settings disconect the Virtual Switch and after 1 minutes add back the Virtual Switch in Network Adapter.

I have an application which use Visual Fox Pro and i suspect that this cause the problem.

But how can track down this behavior to find the cause of the error

I have a VMWare 5.5/5.1 environment and a Hyper V 2016 (Nano) environment. We're running IIS servers in both environments. The servers on VMWare perform at acceptable speed for IIS but the HyperV ones are dramatically slower (3-6x slower). For example, uploading to the IIS FTP on VMWare we'll pull 9MBytes/second (makes sense for our connection) and 1.5MBytes/second on the Hyper V one. The problem occurs on our Web apps too, a site that loads 23MBytes of data takes ~3 seconds from the guests on VMWare and 16-20 on the Hyepr V guests.

Previously we did a V2V of the IIS servers on the VMWare environment and noticed this problem, so we left them on the VMWare environment (they are Windows 2012 R2). The ones on Hyper V are 2016 and are intended to replace those servers. We had mistakenly thought that the issue was with the V2V and that a new server build would fix it.

Extra Info:
-The VMWare hosts are older servers, all servers have multiple teamed Gigabit NICs. VMQ is disabled on the Hyper V guests.
-Servers are on the latest updates since 2/10 (some even more up to date)
-SMBv2 Copies are 90+MBytes/second (limited by a firewall)
We used Sysinternals' Disk2VHD to convert an HP desktop running Windows 7 Home into a first-generation VDMX.  It was saved over the network on a new PC running Windows 10 Pro with Hyper-V (we saved the primary partition only, not the HP recovery).  Now when starting the VM, it just shows a blinking cursor and doesn't go anywhere from there.

Is there anything I should do to correct this?

We have had this issue for a while on a server 2012 r2 running hyper V.
Whenever we try to reboot the server or just restart the Hyper V service. it fails to stop.

I have been reading some articles online but have not found a definitive fix except to uninstall RRAS service or uncheck a setting in the Vswitch properties.
(Allow Management operating system to share this network adapter) this needs to be unchecked.

Or i read other articles to use a second nic which the server does have 2.

Does anyone know of any other possible fixes or if Microsoft solved this in an update?

We're considering a change from VMware to Hyper-V (Windows server 2016) when buying new host servers, however we would like to use SSD Cache.
This is supported with WMware. Does hyper-V support SSD cache?

Our VM's stored in a Dell Equallogic SAN - mix of 7.2K SATA and 10K SAS drives.
Hi There,
I'm new in Hyper-V. I explain the requirement and you give me your advise about hardware and software. (we try to keep the cost minimum).  

We need to setup a set of VM for test and development:
- It's not production and a VM can be done for a day until it restore.
- Around 4-5 Ubuntu Linux and 2-3 Windows 10.  
- If one VM or machine crashes I like to be able to restore it easily to the second hardware.  
- In my wish list I eventually I like to have some high availability. (Depends on cost.)
How can I setup this with minimum cost? if i want to get a bit more HA how would be the cost?

For hardware:
We are thinking about getting 2 used/refurbished Dell server, maybe: Dell PowerEdge R620 with 2*Xeon
any thought or suggestion about hardware?
Please let me know what you think.
Thank you in advanced
Hi All,

I just wanted to get some opinions on Veeam Replication. I have a two server site, both servers are Hyper V hosts with two VM's on each, one VM on the first Host is a DC that holds all the FSMO roles, second server has a backup DC VM

Both of these DC's are gettings backed up with Veeam to a NAS, I also have the DC with the FSMO roles replicating to the other Hyper V Host.

Is it best practice to have this FSMO holding DC replicated which i could fail over with Veeam if i loose it, or is it better to just have the backup, if I lose the FSMO DC, rather seize the FSMO roles on the backup DC and build a new DC, transfer roles back etc.

The replication job of the FSMO DC is working perfect with Application Aware enabled.

Veeam's articles kinda suggest its ok but other forums suggest that FSMO transfer or Seize would be better.

I appreciate any advice or suggestions

I have been trying to setup a Hyper-V proof of concept system for quite some time. I am using a free Microsoft eBook titled "Deploying Hyper-V with Software Defined Storage & Networking" by Mitch Tulloch. There are probably other ways to do this, maybe better ways but this is the way I chose to do it. I have attached the eBook to this question for reference.

I am having an issue with configuring network virtualization. The steps used have you adding a couple of Gateway VMs through downloadable service templates from Microsoft. You deploy then configure these gateway VMs, create a configure a VM network and then deploy a couple of VMs on the compute host group to prove connectivity. Except the connectivity is not there. Neither VM can "see" outside its subnet as if the gateway is not doing its job.

I think the issue lies in the part where I am supposed to "configure your physical switch infrastructure to be able to route traffic into and out of this VM network and the respective virtual subnets" I am really not sure what this means.

I know this is really high-level but please ask any questions for the detail that matters to you.

Have multiple VMs hosted on a W2k12R2 machine. Several VMs are able to create and delete checkpoints without issue. Two of them cannot create a checkpoint, throwing an error indicating that the limit of 50 checkpoints has been reached.

Problem is the "checkpoints" section in Hyper-V manager says "The selected virtual machine has no checkpoints"

If I navigate to the snapshots folder it is full of 50 folders and 50 XML files with complementary names, but the folders are all empty.

If I use the command "get-vmsnapshot -vmname" on the VM names in Powershell it returns no snapshots
My layout is as follows:
I have a physical server that has 5 VMs - Host is Windows 2012 R2
1-Domain controller
1-Exchange (2013)
1-SQL Server 2012
1-Data Server
1-Application Server

I also have another Physical Server that has a replica of all of these VMs. Host is Windows 2012 R2
The replication is working fine.

I am running out of disk space on both physical servers and adding disk space need to turn off the servers which I cannot afford.

I got a new server (rented one for 1 week) with enough space.. and I did set it up as extended replicas from Server2.
and the extended replication is working fine.

Now I am about to take the step of "fail over" from the 3rd server (where I have the extended replication.)
But I have never done this and I am quite unsure about the steps...
Can someone please help me on how to do this "the safest" possible way ?
I was thinking of turning off my primary server (Host) and THEN fail over from the 3rd Server. THEN turn off the second server once all is ok.
If there is anything wrong,  I can then turn back ON the primary.
Is this the right way of doing things ?
yum -y install epel-release fails with error "no package epel-release available"

I have tried adding epel manually without success. I am on a hyper-V with CENTOS v 7 installed. This is my 3rd installation and I always get stuck at this step no matter which version of CENTOS I use.  I have internet connection just fine through firefox and am able I can ping mirrors.fedoraproject.org fine so I'm reading that means my DNS can't resolve host. I tried editing my host file too but this should be easier than all this.  I am just trying to install Moodle and this step is holding me back.
We have to create a replication from server2016 (A)  with gui to server2016 without gui (core) (B). Both are not in the domain. I cant connect  to from A to B over hyper-V-manager. How can we set up a replication from A to B using powershell ?
Is there any good and easy to understand tutorial ?

Thanks for helping
I have a 2008 r2 enterprise server running terminal services and hyper-v. I recently added Windows Server Backup and it does not list Hyper-v as an item to add to my backups. I've read through several forums and I'm not satisfied with what I found so far.
I have created two node hyper-v 2016 failover cluster. The cluster has been sucessfully created and I can migrate the machine successfully between nodes. However, I am not able to see the option "Add to cluster Share Volumes " to add enable the disks as cluster share volumes. I have attached the screenshot below and you may see there is no option "Add to cluster Share Volumes " for disks.   Why this option is not appearing and now what should I need to do?
